初二关于过年的英语日记20词左右

       1， Spring Festiva is 日记the most important festivity for the Chinese people. It is also called the Chinese new year or the Lunar New Year. Every year has an animal’s name. These animals are the rat, ox, tiger, rabbit, dragon, snake, horse, ram, monkey, rooster, dog and pig. A Chinese legend says that these twelve animals had a race. The first year was named after the rat, the winner. The other eleven years were named after the order in which the animals arrived in the race. The clever rat jumped onto the ox’s back then at the end jumped over the ox’s head to arrive first! The Chinese believe that a person born in a particular year has some of the characteristics of animal. On Chinese New Year’s Eve all family members enjoy a big, delicious meal. It is very important for the Chinese to be with their families on this occasion. Fish is always part of the dinner because it represents abundance. On New Year’s Day all Chinese children wear new clothes with bright colors. Red is considered a lucky color. Parents and relatives give children the traditional New Year’s gift called lucky money. This money is put into bright red and gold envelopes. Fill under the pillow. in the morning of new year , the kid wakes up to see the “lucky money”, express that oneself become one year older. Red is a traditional color for festivals, celebrations, weddings and birthdays. The lion dancers are always part of the festivities. The lion has a big head and long body made of cloth. The lion dance is accompanied by drums, cymbals and noisy firecrackers. According to ancient traditions the great noise frightens away evil spirits. The dragon is the most important figure of the Chinese New Year festivities and parades. The dragon is considered a lucky figure. A parade dragon can be to meters long! Sixty or more men move under a long cloth that represents the dragon’s tail. During the parade children represent the animals of the Chinese calendar. There are also acrobats and musicians in beautif

SpringCloud原理OpenFeign原来是这么基于Ribbon来实现负载均衡的

       欢迎来到本篇文章，之前我们已经深入探讨了OpenFeign的源码动态代理生成原理和Ribbon的运行机制。若要对OpenFeign的日记动态代理生成原理和Ribbon的运行原理有更深入的了解，可关注微信公众号“三友的源码java日记”，通过菜单栏查看整理的日记柳暗花明指标源码相关内容。接下来，源码我们将继续深入SpringCloud组件原理，日记探讨OpenFeign是源码如何利用Ribbon实现负载均衡的，以及两组件如何协同工作的日记。

       一、源码Feign动态代理调用实现rpc流程解析

       我们从Feign客户端接口的日记动态代理生成原理出发，了解到动态代理基于JDK实现，源码所有方法调用最终都会调用到InvocationHandler接口的日记实现，即ReflectiveFeign.FeignInvocationHandler。源码交叉端呼叫源码接下来，我们将深入探讨FeignInvocationHandler如何实现rpc调用。

       FeignInvocationHandler通过invoke方法实现动态代理功能，其主要逻辑如下：

       1. 对于调用的方法是否为equals、hashCode、toString等特殊方法进行判断，若为则无需走rpc调用。世纪金源码头

       2. 从dispatch获取调用方法对应的MethodHandler，然后调用MethodHandler的invoke方法。

       3. MethodHandler在构建动态代理时生成，作用是最终实现rpc调用，每个方法有对应的MethodHandler。

       4. SynchronousMethodHandler是实现rpc调用的关键类，通过构造RequestTemplate、php中专作品源码Options和重试组件，发起http请求，并通过Client接口执行请求，返回响应数据。

       二、LoadBalancerFeignClient与Ribbon整合

       从整个动态代理调用流程来看，Client是信源码的格式关键组件，负责发送http请求。Feign是如何通过Ribbon实现负载均衡的呢？让我们进一步剖析。

       通过整合配置类FeignRibbonClientAutoConfiguration，我们可以找到构造Feign.Builder实现的关键组件：LoadBalancerFeignClient。这个组件依赖于负载均衡，是Feign与Ribbon集成的入口。

       LoadBalancerFeignClient实现的核心逻辑在于从请求的URL中提取服务名，通过缓存机制获取或创建FeignLoadBalancer，最终调用executeWithLoadBalancer方法发起请求，完成负载均衡与服务调用。

       三、FeignLoadBalancer实现负载均衡与发送请求

       FeignLoadBalancer是实现选择负载均衡和发送http请求的关键组件。其核心逻辑在于重构请求路径，将服务名替换为具体的服务器IP和端口，然后通过execute方法完成请求。

       四、总结与图解

       本篇文章完整阐述了OpenFeign、Ribbon与注册中心之间的协同工作原理。通过总结，我们了解到OpenFeign在进行RPC调用时，借助Ribbon选择负载均衡服务器，而Ribbon从注册中心获取服务器列表。通过这张图，我们可以清晰地看到三个组件之间的协同关系。

       至此，我们完成了对这三个组件核心源码和流程的深入探讨。希望本篇文章能帮助读者理解微服务架构的基础原理，同时对OpenFeign、Ribbon、Nacos源码有更深入的认识。
