什么是配置中心
在分布式系统中,由于服务数量巨多,为了方便服务配置文件统一管理,实时更新,所以需要分布式配置中心组件。在Spring Cloud中,有分布式配置中心组件spring cloud config ,它支持配置服务放在配置服务的内存中(即本地),也支持放在远程Git仓库中。在spring cloud config 组件中,分两个角色,一是config server,二是config client。
创建git
并添加一个properties类型的文件
创建springcloud_git_server项目

spring.cloud.config.server.git.uri:配置git仓库地址
spring.cloud.config.server.git.searchPaths:配置仓库路径
spring.cloud.config.label:配置仓库的分支
spring.cloud.config.server.git.username:访问git仓库的用户名
spring.cloud.config.server.git.password:访问git仓库的用户密码
启动类
package com.git.springcloud_git_server; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.config.server.EnableConfigServer; @SpringBootApplication @EnableConfigServer public class SpringcloudGitServerApplication { public static void main(String[] args) { SpringApplication.run(SpringcloudGitServerApplication.class, args); } }
