Plant Propagation by Layering

Instructions for the Home Gardener

Introduction

Skip to Introduction

Stems that are still attached to their parent plant may form roots where they come in contact with a rooting medium. This method of vegetative propagation is generally successful, because water stress is minimized and carbohydrate and mineral nutrient levels are high. The development of roots on a stem while the stem is still attached to the parent plant is called layering. A layer is the rooted stem following detachment (removal) from the parent plant.

Some plants propagate naturally by layering, but sometimes plant propagators assist the process. Layering is enhanced by wounding the stem where the roots are to form. The rooting medium should always provide aeration and a constant supply of moisture.

Simple Layering

Skip to Simple Layering

Simple layering can be accomplished by bending a low growing, flexible stem to the ground. Cover part of it with soil, leaving the remaining 6 to 12 inches above the soil. Bend the tip into a vertical position and stake in place (Figure 1). The sharp bend will often induce rooting, but wounding the lower side of the bent branch may help also. Simple layering can be done on most plants with low-growing branches. Examples of plants propagated by simple layering include climbing roses, forsythia, rhododendron, honeysuckle, boxwood, azalea, and wax myrtle.

Simple layering can be done in early spring using a dormant branch, or in late summer using a mature branch. Periodically check for adequate moisture and for the formation of roots. It may take one or more seasons before the layer is ready to be removed for transplanting.

Tip Layering

Skip to Tip Layering

Tip layering is quite similar to simple layering. Dig a hole 3 to 4 inches deep. Insert the tip of a current season’s shoot and cover it with soil. The tip grows downward first, then bends sharply and grows upward. Roots form at the bend. The re-curved tip becomes a new plant (Figure 2). Remove the tip layer and plant it in late fall or early spring. Examples of plants propagated by tip layering include purple and black raspberries, and trailing blackberries.

Figure 2. Tip layering.

×

Compound (serpentine) Layering

Skip to Compound (serpentine) Layering

Compound (serpentine) layering is similar to simple layering, but several layers can result from a single stem. Bend the stem to the rooting medium as for simple layering, but alternately cover and expose sections of the stem. Each section should have at least one bud exposed and one bud covered with soil. Wound the lower side of each stem section to be covered (Figure 3). This method works well for plants producing vine-like growth such as heart-leaf philodendron, pothos, wisteria, clematis, and grapes.

Figure 3. Compound (serpentine) layering.

Mound (stool) Layering

Skip to Mound (stool) Layering

Mound (stool) layering is useful with heavy-stemmed, closely branched shrubs and rootstocks of tree fruits. Cut the plant back to 1 inch above the soil surface in the dormant season. Dormant buds will produce new shoots in the spring. Mound soil over the new shoots as they grow (Figure 4). Roots will develop at the bases of the young shoots. Remove the layers in the dormant season. Mound layering works well on apple rootstocks, spirea, quince, daphne, magnolia, and cotoneaster.

Air Layering

Skip to Air Layering

Air layering can be used to propagate large, overgrown house plants such as rubber plant, croton, or dieffenbachia that have lost most of their lower leaves. Woody ornamentals such as azalea, camellia, magnolia, oleander, and holly can also be propagated by air layering. For optimum rooting, make air layers in the spring on shoots produced during the previous season or in mid to late summer on shoots from the current season’s growth. For woody plants, stems of pencil size diameter or larger are best. Choose an area just below a node and remove leaves and twigs on the stem 3 to 4 inches above and below this point. This is normally done on a stem about 1 foot from the tip.

Air layering differs, depending on whether the plant is a monocot or a dicot. For monocots, make an upward 1- to 11⁄2-inch cut about one-third through the stem. The cut is held open with a toothpick or wooden match stick. Surround the wound with moist, unmilled sphagnum moss (about a handful) that has been soaked in water and squeezed to remove excess moisture. Wrap the moss with plastic and hold in place with twist ties or electrician’s tape. No moss should extend beyond the ends of the plastic. Fasten each end of the plastic securely, to retain moisture and to prevent water from entering. If exposed to the sun, the plastic should be covered. Aluminum foil can also be used, as it does not require twist ties or tape to hold it in place.

The process for dicots is similar, except a 1-inch ring of bark is removed from the stem. With a sharp knife, make two parallel cuts about an inch apart around the stem and through the bark and cambium layer (see Figure 5). Connect the two parallel cuts with one long cut. Remove the ring of bark, leaving the inner woody tissue exposed. Scrape the newly bared ring to remove the cambial tissue to prevent a bridge of callus tissue from forming. Application of a root-promoting substance to the exposed wound is sometimes beneficial. Wrap and cover using the same procedure as that described for monocots.

After the rooting medium is filled with roots, sever the stem below the medium and pot the layer. The new plant will usually require some pampering until the root system becomes more developed. Provide shade and adequate moisture until the plant is well established.

Natural Forms of Layering

Skip to Natural Forms of Layering

Sometimes layering occurs naturally, without the assistance of a propagator. Runners and offsets are specialized plant structures that facilitate propagation by layering.

A runner produces new shoots where it touches the growing medium (Figure 6). Plants that produce stolons or runners are propagated by severing the new plants from their parent stems. Plantlets at the tips of runners may be rooted while still attached to the parent or detached and placed in a rooting medium. Examples include strawberry and spider plant.

Plants with rosetted stems often reproduce by forming new shoots, called offshoots, at their base or in the leaf axles. Sever the new shoots from the parent plant after they have developed their own root systems. Unrooted offsets of some species may be removed and placed in a rooting medium. Some of these must be cut off, whereas others may simply be lifted from the parent stem. Examples include date palm, bromeliads, and many cacti.

Kochi-Ice’s ‘Made in土佐’ ice cream flavours stretch from rice, salt, brown sugar, Sencha, English tea to egg, with vanilla as a ‘base’. Rice grown locally in Kochi-ken is used in its rice ice cream, adding a touch of sticky texture; sea salt from Kuroshio-cho gives a punch of saltiness to the sweet flavour, with health enhancing minerals – even more so when eaten with rice ice cream; English tea ice cream is like chewing (or sipping, depending on your habit) through an iced white tea; Sencha sourced from Ikegawa has a bitter undertone; protein-packed egg flavour is a layering of milk and egg, and not too sweet; brown sugar ice cream is scattered with crystalised sugar pieces. think-silly.com

Staying warm and dry in the outdoors is no easy feat. When the wind, rain, and snow conspire against you, being comfortable while camping can be a challenge, to say the least. 

Thankfully, there is a way that you can dress to ensure that you stay cozy, regardless of what the conditions bring.

The answer? Layering.

Dressing in layers can make a huge difference in your overall camping experience. In fact, layering is a key skill that all outdoor enthusiasts should know. However, dressing for the outdoors is a skill that takes time to perfect, so it can take some trial and error to streamline your personal layering system. 

To speed up the learning process and to ensure that you have all the information you need to need to get outside, here’s our ultimate guide to layering to get you started.

What Does It Mean To Dress In Layers?

You probably hear a lot of folks in the outdoor world talking about “layering,” but what exactly does it mean to dress in layers?

Simply put, dressing in layers means that you wear multiple jackets and pants at any given time so that you can regulate your warmth and weather-resistance based on the changing conditions and your personal comfort levels.

Most layering systems follow a 3 layer approach, which includes the following:

Base Layer. Your base layer, or your underwear layer, is the bottom of the layering pyramid. It’s designed to wick moisture and sweat off your skin to keep you cool and dry as you hike.

Mid Layer. As the name suggests, mid-layers are the middle layers in this system. They’re your insulating jackets, like your fleeces and puffies, which are designed to keep you warm.

Outer Layer. Finally, the outer layer is your waterproof and windproof jacket that provides protection from the elements, most common material are Patagonia’s H2nO and gore-tex.

We’ll go over each of these different layers in more detail in a bit, but understanding the fundamentals of what each layer in the system is meant to do is essential to your camping experience.

RELATED How To Make A Camping Tent From Scratch: An Emergency Shelter, or For FunWhy Is Layering Important?

Dressing in layers while camping is of the utmost importance because it gives you the ability to quickly alter your clothing choices in response to changing weather conditions or increased activity levels.

For example, you’ll probably find that you feel much colder when you’re just sitting around your campsite than you are when you’re making your way up a steep trail. So, instead of having to completely change your outfit before you leave camp each morning, layering allows you to take off a few jackets so that you’re instantly ready for your day of hiking.

Alternatively, if it starts to rain while you’re hiking, dressing in layers makes it easier for you to quickly put on your rain jacket and rain pants without having to change everything that you’re wearing.

As you can see, in a situation with rapidly changing weather conditions like you’ll find outside, dressing in layers gives you the flexibility you need to ensure that you always stay warm and dry.

Now that we understand why layer is important, let’s dive into the nitty-gritty of how to dress in layers for camping. In this section, we’ll discuss some of the principles of layering and then give you an in-depth look at the different aspects of each part of the layering system.

Principles Of Layering

On the face of it, layering is a fairly straightforward concept. However, there are a few important principles that everyone ought to keep in mind as they pack for an outdoor adventure. Here’s what you need to know:

Outer Layers Need To Fit Over Inner Layers. One of the most important things to keep in mind while layering is that your outer jackets, such as your rain jacket, need to fit over all of your inner layers so you can wear all your layers at once if need be. That means that you’ll often need to get a larger rain jacket than you’d normally wear, just in case it’s both cold and rainy.

Avoid Very Thick Jackets As Mid Layers. Building off of the concept that your jackets all need to fit over each other, it’s generally best to avoid packing very thick fleece or puffy jackets as your mid layers. Although these jackets are nice for walking around town, they are just too thick to make them practical for use within a layering system Indeed, you’ll probably struggle to find a rain jacket that can fit over them.

Pack More Layers Than You Need. When packing for your camping trip, always plan to bring 2 to 3 more layers than you think you actually need. Conditions can change rapidly, so having extra layers on hand can really have a big impact on your camping experience.

Don’t Forget Your Lower Body! While we often focus so much on layering for the upper body (e.g., fleece jackets, puffy jackets, and rain jackets), we sometimes neglect the importance of layering for the lower body. Sure, keeping your core warm is your chief concern, but in very cold conditions, you’ll certainly need to consider what you’ll wear on your lower body to protect you from the frigid temperatures.

The Layering System

The key to dressing in layers is to think of it as a system. Like any good system, layering only works if each item of clothing you wear serves a particular purpose and if each of these layers works well with each other.

So, as we discuss each of the aspects of the layering system in more detail in this section, try to imagine what items of clothing you might already have in your gear closet that would fit well within each category. 

If you need a bit of inspiration for what gear you might need to bring on your adventures, check out our ultimate camping checklist for more guidance!

Layer 1: Base Layer

The primary purpose of a base layer is to wick away moisture from your skin. As your primary source of moisture management on the trail, base layers soak up sweat and then allow it to evaporate, keeping you cool and dry, regardless of the temperatures outside.

Types Of Base Layers

Base layers come in a wide range of different types and styles, each of which is designed for use in a specific type of environment. Some types of base layers you might encounter include:

T-shirts

Long sleeve shirts

Sun shirts

Lightweight 1/4 zip pullovers

Long underwear pants

Base Layer Key Characteristics

As you can see, there are many different types of base layers out there, but they all generally share a few key traits, such as:

Non-Cotton Materials. You will rarely, if ever, find a purpose-built base layer that’s made from cotton. That’s because cotton absorbs a lot of moisture but actually makes you colder when it’s wet – something that’s not exactly great while camping in cold environments. Therefore, most base layers are made from synthetic fabrics, merino wool, or other non-cotton materials.

Relatively Thin. Although base layers do come in a range of thicknesses, from ‘ultra lightweight’ to ‘expedition weight’, you’ll generally find that most base layers are made to be quite thin. This is because the primary purpose of a base layer is to wick moisture, not to keep you warm.

UPF Ratings. Many base layers designed for use in the summer actually boast UPF ratings, which means that they offer some protection from the sun’s rays. You’ll find these ratings mostly on T-shirts and purpose-built sun-shirts, so keep a lookout for them if you’re shopping for summer camping base layers.

Base Layer Sizing & Fit

Finally, as far as fit goes, you actually have quite a bit of leeway in deciding how tightly or loosely fitting you like your base layers. While some campers prefer more form-fitting baselayers, others find that a loose-fitting t-shirt is more comfortable, especially during the summer months.

Layer 2: Mid Layer

While base layers are designed to wick sweat away from your body, mid layers are made to keep you warm. In other words, mid layers are your insulating layers, so they’re what you use to trap in body heat to protect you from the frigid cold temperatures outside.

Types of Mid Layers

Unlike base layers, which really run the gamut in terms of the different types of clothing available to you, there are really just 3 types of mid layers: insulated jackets, insulated pants, and vests.

Insulated jackets, which include fleece, synthetic, and down-filled models, are usually your go-to layers for staying warm in the outdoors. 

Vests, on the other hand, can be a useful addition to any layering system. While they’re generally not warm enough to use on their own in the outdoors, a vest can be a light, packable option for extra insulation on particularly chilly nights.

Finally, we have insulated pants, which are really only popular while winter camping. These insulated pants can be made from fleece, down, or synthetic fill and they’re super cozy for use in frosty environments.

Mid Layer Key Characteristics

Since the primary purpose of a mid layer is to keep you warm, the type of insulation that a mid layer uses (whether that’s a jacket or a vest) is of the utmost importance. Here are some of the different insulation options you might encounter while building your layering system:

Down. Down insulation is made from the down plumes of ducks and geese. These plumes are pricey, but they offer an exceptional warmth to weight ratio, which makes them ideal for light and fast missions into the mountains. But, down doesn’t offer any insulating value when wet so it’s less ideal for use in wet locales.

Synthetic. Unlike down, which is a natural material, synthetic insulation is actually a collection of very thin nylon and polyester fibers. These fibers are then bunched together in order to mimic the insulating qualities of down. In general, synthetic insulation is more affordable, though it’s generally heavier and bulkier than down. That being said, synthetic fill can keep you warm when it’s wet.

Fleece. There are actually many kinds of fleece out there, so the best way to decide which is best for your needs is to look at the fabric weight. Most companies market their fleece jackets using the Polartec scale (i.e., 100, 200, or 300), with higher numbers indicating thicker fabrics and more warmth. The main benefits of fleece are that it’s affordable, breathable and can keep you warm when wet. However, it tends to be heavy, bulky, and not very wind-resistant.

Mid Layer Sizing & Fit

Since your mid layers are sandwiched between your base layers and outer layers, sizing and fit are very important. 

As we’ve mentioned previously, it’s important that your mid layers aren’t too bulky, or you’ll have a hard time fitting them under your outer layers. 

At the same time, if you plan on wearing multiple mid layers, you’ll need to figure out what order you want to layer them in, so you can ensure that all your jackets fit over each other without limiting your range of motion on the trail.

Layer 3: Outer Layer

Aptly named, your outer layer (a.k.a. shell layer) is, well, your outer jacket or outer layer of pants. Outer layers, like rain pants and rain jackets, are designed to protect you from the wind and the rain, so they’re your primary line of defense against the elements. 

Depending on the conditions you actually expect to face on your adventures, your outer layer might spend a lot of time in your backpack. But, it’s important to have a shell layer ready to go at all times if the weather turns sour.

Types of Outer Layers

In general, the vast majority of campers use rain jackets and rain pants for their outer layers. That’s because rain jackets and rain pants provide the best protection from the wind and the rain, so they’re ideal for use in most wet environments.

However, you may find that a soft shell jacket, a wind jacket, or a pair of softshell hiking pants might be more appropriate for the conditions you’ll face. While soft shell fabrics aren’t usually waterproof (they’re generally water-resistant), they’re much more breathable, which makes them great for light rain or general hiking purposes in nice weather.

Outer Layer Key Characteristics

Nearly all outer layers designed for use while hiking and camping will be waterproof and windproof. These jackets almost always use some sort of waterproof breathable membrane, like H2NO or Gore-Tex, which can provide ample weather-resistance while still allowing sweat to evaporate.

Other useful features you might find on an outer layer include:

Hood. Protects your head from the wind and the rain. Some helmets are designed to go over a climbing helmet and others are not.

Pockets. For on-the-fly gear storage on the trail. Many different shapes, sizes, and configurations are available.

Adjustable Cuffs. To seal out precipitation and moisture in foul conditions.

Zippered Armpit Vents. Allows for increased breathability while hiking in humid environments.

Zippered Thigh Vents. Provides added ventilation for your rain pants in hot, humid, and rainy locales.

RECCO Reflectors. Lightweight reflectors that are sewn into some winter gear to help rescuers find you after an avalanche.

Outer Layer Sizing & Fit

Outer layers have a tough job because they need to be able to fit over all of your other layers, just in case you find yourself in a cold and wet environment. 

As a result, it’s generally best to get a rain jacket that’s a bit bigger than you think you need so that it doesn’t feel constricting when you put it on over your base layers and mid layers. 

The same is true for rain pants, but keep in mind that you’ll usually only put your rain pants over your hiking pants and maybe a set of base layers, so don’t size your pants too large.

At this point, you have a solid theoretical understanding of how to layer for camping and hiking. However, putting all of this information together into a system that works for you while you’re outside can be tricky.

To help you out, this section will offer up an example of a layering system that you might use while summer or winter camping. 

Of course, what system you use will depend on your personal gear inventory and the conditions you face. But, we hope that this information serves as a helpful starting point as you plan.

How To Dress In Layers For Summer Camping

Summer camping can involve super hot conditions in the desert or breezy, rainy, and moderate conditions in the mountains. So, there’s actually no one-size-fits-all solution to layering for summer adventures.

That being said, layering for summer camping starts with identifying the conditions you’ll face and creating a clothing system that directly addresses those needs. You may find that you don’t really need base layer pants or rain pants in the desert, but that these are a must in the alpine.

With that in mind here are some example summertime layering systems to use as inspiration for your trips.

Hot & Sunny Camping

Base Layer: Merino or synthetic T-shirt with a UPF sunshirt and a pair of breathable hiking pants.

Mid Layer: Lightweight puffy jacket and fleece for staying warm on chilly nights.

Outer Layer: Wind jacket or a lightweight rain jacket for breezy days. Rain pants optional based on the climate.

Cool, Wet & Breezy Camping

Base Layer: Merino or synthetic T-shirt or long-sleeve wicking shirt with breathable softshell hiking pants. Baselayer pants optional based on the conditions.

Mid Layer: 2 to 3 midweight puffy and fleece jackets for warmth during the day and night. Consider a vest if you tend to get cold.

Outer Layer: Rain jacket and rain pants for foul weather. Wind jackets and soft shell jackets optional, but helpful.

How To Dress In Layers For Winter Camping

Layering for winter camping is challenging but incredibly important because your clothing is your primary line of defense against the cold and the snow. While the number of layers you pack and wear while winter camping will depend greatly on the temperatures you expect to face, the principles of layering are the same.

Here’s how you dress in layers for winter camping:

Base Layer: Merino or synthetic long-sleeve shirts and long underwear. Opt for base layers that are labeled as ‘mid-weight’ or ‘expedition weight’ as these provide a bit of warmth in addition to their moisture-wicking abilities.

Mid Layers: Your mid-layers choices will vary a lot depending on the temperature. Bring at least a fleece jacket and 1 to 2 puffy jackets for all-day warmth. Also, be sure to pack 2 to 3 extra jackets as well as puffy or fleece pants, just in case the temperatures are colder than you expect.

Outer Layers. Winter camping requires that you bring 2 sets of outer layers: 1 set that can keep you dry and the other for use in extreme cold. Bring rain pants and a rain jacket to keep you dry and an extra-large puffy for when the mercury drops. Additionally, don’t forget to pack plenty of hats and gloves to keep you warm and dry.

前言

对于系统查多改少的数据,可以通过缓存来提升系统的访问性能。一般情况下我们会采用 Redis ,但是如果仅仅依赖 Redis 很容易出现缓存雪崩的情况。为了防止缓存雪崩可以通过 Redis 高可用,主从+哨兵解决方案、本地 ehcache 缓存 + hystrix 限流&降级、Redis 持久化 等手段有效的防止缓存雪崩。其中同时使用本地缓存和Redis 缓存就是两级缓存。本文主要介绍的内容就是:在SpringBoot 项目下实现两级缓存,具体的介绍内容如下:

什么是缓存雪崩?什么是两级缓存?SpringBoot 实现两级缓存解决方案。SpringBoot 集成 layering-cache 实现两级缓存

什么是缓存雪崩?

对于不了解什么是缓存雪崩小伙伴,这里在简单的介绍一下。如果您了解什么是缓存雪崩可以绕过该小节。

对于系统 A,假设每天高峰期每秒 5000 个请求,本来缓存在高峰期可以扛住每秒 4000 个请求,但是缓存机器意外发生了全盘宕机。缓存挂了,此时 1 秒 5000 个请求全部落数据库,数据库必然扛不住,它会报一下警,然后就挂了。此时,如果没有采用什么特别的方案来处理这个故障,DBA 很着急,重启数据库,但是数据库立马又被新的流量给打死了。

这就是缓存雪崩。

为了防止缓存雪崩,一般会采用方式如下:

事前:Redis 高可用,主从+哨兵,Redis cluster,避免全盘崩溃。 事中:本地 Ehcache 缓存 + Hystrix 限流&降级,避免 MySQL 被打死。 事后:Redis 持久化,一旦重启,自动从磁盘上加载数据,快速恢复缓存数据。

缓存雪崩介绍引用 https://github.com/shishan100/Java-Interview-Advanced 中华石杉–互联网Java进阶面试训练营

什么是两级缓存?

一级缓存就是:本地缓存,二级缓存就是:Redis。当访问请求过来的时候,先从一级缓存获取数据,如果一级缓存不存在则从二级缓存中获取,从二级缓存获取到数据后在将其设置到一级缓存。

为什么两级缓存可以防止缓存雪崩?

当Redis 宕机后请求会获取本地缓存而不是直接走MySql 来防止缓存雪崩。还有一点是: Redis缓存操作会有一大部分的网络开销,使用本地缓存可以避免网络开销,提升系统的性能。

SpringBoot 实现两级缓存解决方案

Spring Cache

Spring Cache 是 Spring 默认提供的缓存解决方案,如果是单独使用 一级或二级缓存,比较容易实现。但是如果结合使用,需要自己处理缓存同步、二级缓存等功能。

Alibaba JetCache 框架

JetCache是一个基于Java的缓存系统封装,提供统一的API和注解来简化缓存的使用。 JetCache提供了比SpringCache更加强大的注解,可以原生的支持TTL、两级缓存、分布式自动刷新,还提供了Cache接口用于手工缓存操作。 当前有四个实现,RedisCache、TairCache(此部分未在github开源)、CaffeineCache(in memory)和一个简易的LinkedHashMapCache(in memory),要添加新的实现也是非常简单的。

缺点是:JetCache 没有提供默认 一级缓存和二级缓存同步,需要自己手动实现。

Layering Cache 框架

layering-cache是一个支持分布式环境的多级缓存框架,使用方式和spring-cache类似,主要目的是在使用注解的时候支持配置过期时间。layering-cache其实是一个两级缓存,一级缓存使用Caffeine作为本地缓存,二级缓存使用redis作为集中式缓存。并且基于redis的Pub/Sub做缓存的删除,所以它是一个适用于分布式环境下的一个缓存系统。

支持 支持缓存监控统计 支持缓存过期时间在注解上直接配置 支持二级缓存的自动刷新(当缓存命中并发现缓存将要过期时会开启一个异步线程刷新缓存) 刷新缓存分为强刷新和软刷新,强刷新直接调用缓存方法,软刷新直接改缓存的时间 缓存Key支持SpEL表达式 新增FastJsonRedisSerializer,KryoRedisSerializer序列化,重写String序列化。 支持同一个缓存名称设置不同的过期时间 输出INFO级别的监控统计日志 二级缓存是否允许缓存NULL值支持配置 二级缓存空值允许配置时间倍率

综合 Spring Cache、Alibaba JetCache、Layering Cache 个人推荐使用功能更全的 Layering Cache,接下来正式开启 SpringBoot 集成 layering-cache 实战 !

SpringBoot 集成 layering-cache 实战

application.properties 配置

spring.layering-cache.stats=true

spring.layering-cache.namespace=layering-cache

spring.layering-cache.layeringCacheServletEnabled=true

spring.layering-cache.urlPattern=/layering-cache/*

spring.layering-cache.loginUsername=admin

spring.layering-cache.loginPassword=123456

spring.layering-cache.enableUpdate=true

spring.redis.host=localhost

spring.redis.port=6379

spring.layering-cache.stats = 是否开启缓存统计 true 是 false 否spring.layering-cache.namespace = 命名空间,必须唯一般使用服务名spring.layering-cache.layeringCacheServletEnabled = 是否开启内置的监控页面spring.layering-cache.urlPattern = 内置的监控页面访问路径spring.layering-cache.loginUsername = 内置的监控登录用户账号spring.layering-cache.loginPassword = 内置的监控登录用户密码spring.layering-cache.enableUpdate = 内置的监控是否启用更新权限

引入依赖:

com.github.xiaolyuh

2.0.8

org.springframework.boot

spring-boot-starter-data-redis

org.springframework.boot

配置RedisTemplate:

@Configuration

public class RedisConfig {

@Bean

public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {

return createRedisTemplate(redisConnectionFactory);

}

public RedisTemplate createRedisTemplate(RedisConnectionFactory redisConnectionFactory) {

RedisTemplate redisTemplate = new RedisTemplate<>();

redisTemplate.setConnectionFactory(redisConnectionFactory);

// 使用Jackson2JsonRedisSerialize 替换默认序列化

Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

ObjectMapper objectMapper = new ObjectMapper();

objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);

objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

// 设置value的序列化规则和 key的序列化规则

redisTemplate.setKeySerializer(new StringRedisSerializer());

redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);

//Map

redisTemplate.setHashKeySerializer(new StringRedisSerializer());

redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);

redisTemplate.afterPropertiesSet();

return redisTemplate;

}

}

使用 layering 包中的 @Cacheable @CachePut @CatchEvict 声明一级和一级缓存配置

具体缓存操作 UserService

@Service

public class UserService {

private Logger log = LoggerFactory.getLogger(UserService.class);

/**

* 根据用户Id 获取用户信息

* key:[user:info+userId值] value: [User]

* @param userId

* @return

*/

@Cacheable(value = "user:info", depict = "用户信息缓存", key = "#userId",

firstCache = @FirstCache(expireTime = 2, timeUnit = TimeUnit.SECONDS),

secondaryCache = @SecondaryCache(expireTime = 30, preloadTime = 3, forceRefresh = true, timeUnit = TimeUnit.SECONDS))

public User getUserById(String userId) {

log.info("userId:{}未走缓存",userId);

return new User(userId,"zhuoqianmingyue"+userId, 1);

}

/**

* key:[user:info+userId值] value: [User]

* 根据用户Id 设置缓存

* @param userId

* @return

*/

@CachePut(value = "user:info", key = "#userId", depict = "用户信息缓存",

firstCache = @FirstCache(expireTime = 4, timeUnit = TimeUnit.SECONDS),

secondaryCache = @SecondaryCache(expireTime = 10, preloadTime = 3, forceRefresh = true, timeUnit = TimeUnit.SECONDS))

public User saveUser(String userId) {

log.info("userId:{}设置缓存",userId);

return new User(userId,"zhuoqianmingyue"+userId, 1);

}

/**

* key:[user:info+userId值] value: [User]

* 根据用户Id 删除缓存

* @param userId

*/

@CacheEvict(value = "user:info", key = "#userId")

public void evictUser(String userId) {

log.info("删除userId:{}缓存",userId);

}

/**

* 删除所有用户

*/

@CacheEvict(value = "user:info", allEntries = true)

public void evictAllUser() {

}

}

前台调用Service 的Controller

@RestController

@RequestMapping("/user")

public class UserController {

@Autowired

private UserService userService;

@GetMapping("/{id}")

public User getUserById(@PathVariable String id){

return userService.getUserById(id);

}

@GetMapping("/save/{id}")

public User saveUser(@PathVariable String id){

return userService.saveUser(id);

}

@GetMapping("/delete/{id}")

public void deleteUser(@PathVariable String id){

userService.evictUser(id);

}

@GetMapping("/deleteAll")

public void deleteAllUser(@PathVariable String id){

userService.evictAllUser();

}

}

matlab 实现彩色强度分层技术

05-24

彩色强度分层技术(Color Intensity Layering)是一种图像处理技术,可以将灰度图像转换为彩色图像。

实现彩色强度分层技术的一种方法是,将灰度图像作为三个颜色通道的值(红色、绿色和蓝色),然后根据每个像素的灰度值确定其颜色。

以下是用 MATLAB 实现彩色强度分层技术的代码示例:

```matlab

% 读入灰度图像

I = imread('gray_image.png');

% 将灰度图像作为三个颜色通道的值

I_color = cat(3, I, I, I);

% 确定每个像素的颜色

for i = 1:size(I, 1)

for j = 1:size(I, 2)

if I(i,j) < 64

% 灰度值小于 64,设为蓝色

I_color(i,j,1) = 0;

I_color(i,j,2) = 0;

I_color(i,j,3) = 255;

elseif I(i,j) < 128

% 灰度值大于等于 64,小于 128,设为绿色

I_color(i,j,1) = 0;

I_color(i,j,2) = 255;

I_color(i,j,3) = 0;

elseif I(i,j) < 192

% 灰度值大于等于 128,小于 192,设为黄色

I_color(i,j,1) = 255;

I_color(i,j,2) = 255;

I_color(i,j,3) = 0;

else

% 灰度值大于等于 192,设为红色

I_color(i,j,1) = 255;

I_color(i,j,2) = 0;

I_color(i,j,3) = 0;

end

end

end

% 显示彩色图像

imshow(I_color);

```

在代码中,我们首先读入灰度图像,然后将灰度图像作为三个颜色通道的值,创建一个大小与灰度图像相同的彩色图像。接着,我们使用两个嵌套的循环遍历每个像素,并根据其灰度值确定其颜色。最后,我们显示彩色图像。

可以根据需要修改代码中的灰度值和颜色,以实现不同的效果。

Layering: A Versatile Plant Propagation Technique

Layering is a highly effective method of plant propagation that allows gardeners and horticulturists to create new plants from existing ones. This technique involves encouraging the development of roots on a stem while it is still attached to the parent plant. Layering is particularly useful for plants that are difficult to root from cuttings or those that have a low success rate with other propagation methods. In this article, we will explore the various types of layering, the step-by-step process involved, and the advantages it offers to plant enthusiasts.

Types of Layering

Air Layering (Marcotting)

Air layering, also known as marcotting, is a technique commonly used to propagate woody plants with thick stems. It involves creating a small wound on a stem and then inducing the development of roots on that wounded area. This method allows the stem to remain attached to the parent plant until it establishes a strong root system. Air layering is often employed for plants like magnolias, citrus trees, and camellias.

Simple Layering

Simple layering is a straightforward method suitable for plants with flexible stems that can easily bend and touch the ground. In this technique, a portion of the stem is buried in the soil while still attached to the parent plant. Over time, roots develop at the point of contact with the soil, creating a new, independent plant. Shrubs such as forsythia and honeysuckle are commonly propagated through simple layering.

Serpentine Layering

Serpentine layering is an effective technique used for plants with long, flexible stems. It involves creating a series of shallow wounds along the stem, which are then buried at intervals, resulting in multiple root formations. This method is especially useful for vines like wisteria and grapes, as well as certain ground-cover plants.

The Layering Process

Layering is a relatively straightforward process, although the exact steps may vary slightly depending on the specific type of layering being used. The following steps outline a general approach to layering:

Step 1: Selection of Parent Plant

Choose a healthy and vigorous plant with flexible or woody stems suitable for layering. It’s important to select a plant that is known to respond well to layering for optimal success.

Step 2: Preparing the Stem

Identify a suitable stem on the parent plant that is suitable for layering. The stem should be relatively young, healthy, and free from any diseases or damage. Make a small incision or wound on the stem where roots will form. This can be done by scraping a small portion of the bark or making a shallow cut.

Step 3: Encouraging Root Formation

Apply a rooting hormone to the wounded area to stimulate the growth of roots. This will enhance the chances of successful layering by encouraging the development of new roots at the point of injury.

Step 4: Positioning the Stem

Position the wounded section of the stem in contact with a prepared rooting medium such as moist soil, sphagnum moss, or a mix of soil and peat. Bury the wounded area while ensuring that a portion of the stem remains above the soil line. This allows the buried portion to receive the necessary moisture and nutrients for root development.

Step 5: Stabilizing the Layered Stem

Secure the layered stem in place using plant stakes, wire, or other suitable materials to prevent it from dislodging or moving during the rooting process. This will ensure that the stem remains in contact with the rooting medium and allows the roots to develop undisturbed.

Step 6: Providing Adequate Care

Water the rooting medium regularly to maintain consistent moisture levels. Keep an eye on the layered stem, ensuring it remains healthy and undamaged. Avoid overwatering or allowing the soil to dry out completely, as either extreme can hinder root development.

Step 7: Separating and Transplanting

Once the layered stem has developed a strong root system, it can be separated from the parent plant and transplanted into its own pot or a suitable location in the garden. Carefully remove any supporting materials, taking care not to damage the delicate roots.

Advantages of Layering

Layering offers several advantages over other propagation methods:

Higher Success Rate

Layering has a higher success rate compared to some other methods, as the new plant retains a connection to the parent plant until it establishes its own root system. This connection provides a continuous supply of nutrients and water, increasing the chances of successful rooting.

Genetic Uniformity

Since layering produces a new plant directly from a portion of the parent plant, it ensures genetic uniformity. This is particularly useful when you want to preserve the exact traits and characteristics of a specific cultivar.

Quick Establishment

Layered plants tend to establish more quickly compared to those propagated by seeds. The new plant already has a head start with an established root system, allowing it to grow more vigorously and adapt better to its environment.

Mature Plants in a Shorter Time

By utilizing layering, gardeners can obtain mature plants in a shorter time compared to starting from seeds. This is especially valuable when propagating slow-growing or long-lived species that may take years to reach maturity from seeds.

Conclusion

Layering is a versatile and reliable plant propagation technique that allows you to create new plants from existing ones. Whether you choose air layering, simple layering, or serpentine layering, this method offers a higher success rate, genetic uniformity, quick establishment, and the ability to obtain mature plants in a shorter time. By mastering the art of layering, you can expand your plant collection, preserve desirable traits, and enjoy the satisfaction of creating new life from your favorite plants.

Fluent动网格【14】:Layering

2017-04-24 分类:Fluent动网格

阅读() 评论(0)

内容纲要

Layering是Fluent动网格技术中用于处理拉伸体网格变形的一种非常有效的方法。与光顺方法不同,Layering方法可以处理网格拓扑的变化(如网格节点的增加或删除),因此在Layering方法可以用于变形幅度非常大的场合。

Fluent中的Layering方法

在Fluent中激活Layering方法非常简单,只需在动网格设置中激活选项Layering即可。如下图所示。 

 Layering方法需要设置的参数较少,如下图所示。 

 有两种Layering方法:

Height Based:基于网格高度。

Ratio Based:基于网格高度比率。 两种方法均包含两个参数:

Split Factor:分裂因子。控制网格分裂。

Collapse Factor:坍塌因子。控制网格合并。

基本原理

Layering方法的基本原理很简单,即检测运动边界相连的网格高度,通过设定高度阈值来决定网格是被分裂还是合并。通过设定分裂因子及坍塌因子,并设置一个网格高度值作为参照,即可在边界运动过程中,控制边界相邻网格的合并或分裂。如下图所示,当下方边界运动时,Layering方法计算网格高度以决定是否进行网格的坍塌和分裂。 

 利用在刚体运动定义的Cell Height来计算网格节点间距,如下图所示。 

 设此参数值为h0,则计算方法为:

其中,α为分裂因子split factor,β为坍塌因子collapse factor。

适用性

虽然Layering方法能够保证网格拓扑改变后的质量,但其应用领域存在较大的局限性。

与运动边界相邻的网格必须是三棱柱或六面体(2D中为四边形)网格

运动壁面必须是独立的,如下图所示的情形,则必须使用interface。

在存有悬挂节点的网格区域(如笛卡尔网格)无法使用Layering方法。

一、核心概念

Layering-Cache采用分层架构,将缓存分为多个级别,包括本地缓存、分布式缓存、持久化缓存等。各级缓存之间相互协作,形成一个完整的缓存体系。通过合理的层次划分,Layering-Cache能够根据数据访问特点和系统负载状况,动态调整缓存策略,提高缓存效率和命中率。

二、实现原理

本地缓存:本地缓存位于应用程序内部,用于存储常用数据。由于本地缓存的访问速度最快,因此对于频繁访问的数据,优先存储在本地缓存中。当数据在本地缓存中不存在时,再向上层缓存发起请求。分布式缓存:当本地缓存无法满足数据量需求时,分布式缓存将起到关键作用。它采用集群方式部署,能够存储海量数据并支持高并发访问。分布式缓存通过一致性哈希等技术实现数据分片和负载均衡,确保数据均匀分布在各个节点上,提高系统的可扩展性和可用性。持久化缓存:持久化缓存位于最底层,通常采用关系型数据库或NoSQL数据库实现。当数据需要长期保存或需要支持复杂查询时,将其存储在持久化缓存中。持久化缓存的设计需要考虑数据的一致性和完整性,以及高效的读写性能。

在数据访问过程中,Layering-Cache会根据各级缓存的命中情况以及系统负载状况,动态调整缓存策略。例如,当分布式缓存的访问速度变慢时,Layering-Cache可以自动将部分热点数据迁移到本地缓存或持久化缓存中,以提高整体性能。

三、应用实例

假设我们有一个大型电商网站,面临着高并发、低延迟的挑战。为了提高用户访问速度和系统性能,我们可以采用Layering-Cache框架进行优化。具体步骤如下:

分析业务场景和数据访问特点:首先需要对电商网站的业务场景和数据访问特点进行分析,找出高频访问的商品、用户信息等数据。设计缓存层次结构:根据分析结果,设计合理的缓存层次结构。例如,可以将商品详情页、用户信息等常用数据存储在本地缓存中;将商品分类、搜索结果等数据存储在分布式缓存中;将订单信息、购物车信息等需要持久化存储的数据存储在持久化缓存中。配置缓存策略:根据实际业务需求和系统负载状况,配置合理的缓存策略。例如,可以设置缓存的过期时间、更新策略等。监控与调优:通过Layering-Cache提供的监控工具,实时监控各级缓存的命中率、响应时间等指标,并根据监控结果进行调优。例如,当分布式缓存的命中率下降时,可以增加节点数量或调整数据分布策略。

通过以上步骤,我们可以使用Layering-Cache框架对电商网站进行优化,提高系统的性能和用户体验。

四、总结

Layering-Cache作为为监控而生的多级缓存框架,通过分层架构和动态调整策略,提高了缓存效率和系统性能。在实际应用中,我们需要根据业务场景和数据特点合理设计缓存层次结构和策略,并借助监控工具进行实时调优。随着技术的发展和业务需求的变化,Layering-Cache仍需不断优化和完善,以满足更多场景的需求。

layering-cache

简介

layering-cache是一个支持分布式环境的多级缓存框架,使用方式和spring-cache类似。它使用Caffeine作为一级本地缓存,redis作为二级集中式缓存。一级缓存和二级缓存的数据一致性是通过推和拉两种模式相结合的方式来保证。推主要是基于redis的pub/sub机制,拉主要是基于消息队列和记录消费消息的偏移量来实现的。

支持

支持缓存命中率的监控统计,统计数据上报支持自定义扩展

内置dashboard,支持对缓存的管理和缓存命中率的查看

支持缓存过期时间在注解上直接配置

支持缓存的自动刷新(当缓存命中并发现二级缓存将要过期时,会开启一个异步线程刷新缓存)

缓存Key支持SpEL表达式

Redis支持Kryo、FastJson、Jackson、Jdk和Protostuff序列化,默认使用Protostuff序列化,并支持自定义的序列化

支持同一个缓存名称设置不同的过期时间

支持禁用一级缓存,只使用二级缓存

优势

提供缓存命中率的监控统计,统计数据上报支持自定义扩展

支持本地缓存和集中式两级缓存

接入成本和使用成本都非常低

无缝集成Spring、Spring boot

内置dashboard使得缓存具备可运维性

通过缓存空值来解决缓存穿透问题、通过异步加载缓存的方式来解决缓存击穿和雪崩问题

重要提示

layering-cache支持同一个缓存名称设置不同的过期时间,但是一定要保证key唯一,否则会出现缓存过期时间错乱的情况

删除缓存的时候会将同一个缓存名称的不同的过期时间的缓存都删掉

在集成layering-cache之前还需要添加以下的依赖,主要是为了减少jar包冲突(依赖jar列表)。

redis的key序列化方式必须StringRedisSerializer

生产力:来评估开源项目输出软件制品和开源价值的能力。

创新力:用于评估开源软件及其生态系统的多样化程度。

稳健性:用于评估开源项目面对多变的发展环境,抵御内外干扰并自我恢复的能力。

2. 协作、人、软件

协作:代表了开源开发行为中协作的程度和深度。

人:观察开源项目核心人员在开源项目中的影响力,并通过第三方视角考察用户和开发者对开源项目的评价。

软件:从开源项目对外输出的制品评估其价值最终落脚点。也是开源评估最“古老”的主流方向之一“开源软件” 的具体表现。

3. 评估模型

基于“开源生态”与“协作、人、软件”的维度,找到与该目标直接或间接相关的可量化指标,对开源项目健康与生态进行量化评估,最终形成开源评估指数。
