第113天学习打卡（SpringCloud Zuul路由网关 Config）
Zuul路由网关
概述
什么是Zuul?
Zuul包含了对请求的路由和过滤两个主要的功能：
其中路由功能负责将外部请求转发到具体的微服务实例上，是实现外部访问 统一入口的基础，而过滤器功能则负责对请求的处理过程进行干预，是实现请求校验，服务聚合等功能的基础。Zuul和Eureka进行整合，将Zuul自身注册为Eureka服务治理下的应用，同时从Eureka中获取其他微服务的消息，也即以后的访问微服务都是通过Zuul跳转后获得。
注意：Zuu服务最终还是会注册进Eureka
提供：代理 + 路由 + 过滤 三大功能
Zuul能干嘛？
- 路由
- 过滤

SpringCloud config分布式配置
概述
分布式系统面临的–配置文件的问题
微服务意味着要将单体应用中的业务拆分成一个个子服务，每个微服务的粒度相对较小，因此系统中会出现大量的服务，由于每个服务都需要必要的配置信息才能运行，所以一套集中式的，动态的配置管理设施是必不可少的。SpringCloud提供了ConfigServer来解决这个问题，我们每一个微服务都有自己带着一个application.yml。
什么是SpringCloud config分布式配置中心
Spring Cloud Config 为微服务架构中的微服务提供集中化的外部配置支持，配置服务器为各个不同微服务应用的所有环节提供了一个中心化的外部配置。
Spring Cloud Config 分为服务端和客户端两部分；
服务端也称为分布式配置中心，它是一个独立的微服务应用，用来连接配置服务器并为客户端提供获取配置信息，加密，解密信息等访问接口。
客户端则是通过指定的配置中心来管理应用资源，以及与业务相关的配置内容，并在启动的时候从配置中心获取和加载配置信息。配置服务器默认采用git来存储配置信息，这样就有助于对环境配置进行版本管理。并且可以通过git客户端工具来方便的管理和访问配置内容。
SpringCloud config分布式配置中心能干嘛
- 集中管理配置文件
- 不同环境，不同配置，动态化的配置更新，分环境部署，比如/dev/test/prod/beta/release
- 运行期间动态调整配置，不再需要在每个微服务部署的机器上编写配置文件，服务会向配置中心统一拉取配置自己的信息。
- 当配置发生变动时，服务不需要重启，即可感知到配置的变化，并应用新的配置
- 将配置信息以REST接口的形式暴露
SpringCloud config 分布式配置中心与github整合
由于Spring Cloud Config 默认使用Git来存储配置文件（也有其他方式，比如支持SVM和本地文件），但是最推荐的还是Git,而且使用的是http/https访问的形式。
下载Git的地址：Git - Downloading Package (git-scm.com)
Git - Downloads (git-scm.com)
只需要一路点默认就可以了
在码云上创建项目：
码云地址：Gitee - 基于 Git 的代码托管和研发协作平台
在本地中创建一个文件Git,然后点开这个空文件，右键点击Git Bash
如何使用码云的官方地址：使用Gitee - 廖雪峰的官方网站 (liaoxuefeng.com)
在码云上配置SSH公钥：
ssh-keygen -t rsa -C "[email protected]"
就会在本地创建的文件中生成在Gitee下生成的项目：
和gitee 是生成的一样的项目：
在自己创建的Git文件中创建一个application.yml
application.yml 里面的内容
spring:
profiles:
active: dev
---
spring:
profiles: dev
application:
name: springcloud-config-dev
---
spring:
profiles: test
application:
name: springcloud-config-test
把本地配置的application.yml配置到码云上Gitee
上传成功的显示：
服务端连接Git设置 springcloud-config-server-3344
配置依赖pom.xml：

package com.kuang.springcloud;
import org.springframework.boot.SpringApplication;

@SpringBootApplication
@EnableConfigServer //开启服务
public class Config_Server_3344 {
public static void main(String[] args) {
SpringApplication.run(Config_Server_3344.class,args);
}
}
只启动3344端口
访问显示的结果
HTTP服务具有以下格式的资源：
/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
Config 客户端连接服务端连接远程 springcloud-config-client-3355：
在本地文件下添加一个config-server.yml
