ServerConfig

SpringCloud 组件，ServerConfig 是配置服务中心，组件，用于统一管理项目配置’’

原理

读取配置文件内容到服务中心

通过启动一个springboot服务（server-config），配置好git仓库地址（也可以svn或者其他），通过配置好的文件地址，访问配置文件，将配置读取到服务中心，并且文件内容修改后，可以实时刷新。

客户端到配置中心读配置内容

其他微服务访问配置不需要访问git，只需要通过访问ServerConfig读取配置，能到达统一配置的目的。

搭建

前提概要，本搭建使用ide:Spring Tool Suite 4

Version: 4.3.0.RELEASE Build Id: 201906200901

安装好maven 3.6.3，并配置好网络通畅的maven仓库地址，有些国外仓库地址可能网速不好，下载依赖慢。

国内镜像仓库反而更快 https://www.cnblogs.com/Narule/p/12595960.html

@SpringBootApplication  //springboot启动类注解

/**

public class ConfigApplication {

	public static void main(String[] args) {
		SpringApplication.run(ConfigApplication.class, args);
	}
	
}

启动这个类的main方法，看控制台console的打印日志是否启动成功，启动成功，则可以通过

localhost:8888/eureka-dev.yml 查看配置信息，只要配置地址有这个文件

/ { 应用名 } / { 环境名 } [ / { 分支名 } ]
/ { 应用名 } - { 环境名 }.yml
/ { 应用名 } - { 环境名 }.properties
/ { 分支名 } / { 应用名 } - { 环境名 }.yml
/ { 分支名 } / { 应用名 } - { 环境名 }.properties

client 读取配置

如果一个springboot服务叫eureka,eureka配置如下

bootstrap.yml

spring:
  application:
    name: eureka #应用名
  cloud:
    config:
     uri: localhost:8888 #配置中心的访问地址 这不是配置文件的地址，是配置服务server-config的地址
     profile: dev #环境
     label: master #分支
management:
  endpoints:
    web:
      exposure:
        include:
        - "*"
        
eureka:
  server:
    renewal-percent-threshold: 0.45
    
log:
  path: log

那么他会读取的文件名称为eureka-dev.yml, git分支为master的文件(默认)

Client

Client 其实只是在pom中添加 config依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency>

并且在bootstrap.yml 中配置server-config服务的url地址，Client就能自己读取到配置中心服务的数据
