配置中心-基础

配置文件

server:
  port: 8888
spring:
  application:
    name: ConfigServer
  cloud:
    config:
      server:
        git:
          # 配置git仓库地址
          uri: https://gitee.com/_LK/test_work.git
          # 访问git仓库的用户名
#          username:
          # 访问git仓库的用户密码 如果Git仓库为公开仓库，可以不填写用户名和密码，如果是私有仓库需要填写
#          password:
          #支持带{application}和{profile}（{label}如果需要）占位符的搜索路径
          search-paths: '{application}'
      # 配置仓库的分支,可不配
      label: master

配置 git 仓库地址

依赖

        <dependency>

访问 http://127.0.0.1:8888/ConfigClient/dev 返回配置内容

{"name":"ConfigClient","profiles":["dev"],"label":null,"version":"c9c8203c27fc04866a7a67523c6051a057048297","state":null,"propertySources":[{"name":"https://gitee.com/_LK/test_work.git/ConfigClient-dev.properties","source":{"git.value":"456asdasdada"}}]}

配置自动刷新

配置 git 服务器端的webHook,更新后主动推送

Client

bootstrap.yml

建立bootstrap.yml 配置 configServer

spring:
  application:
    name: configclient
  cloud:
    config:
      uri: http://localhost:8888/
      label: master
      profile: dev
server:
  port: 10001

配置文件

加上@RefreshScope注解，git.value 会从配置中心读取值

@SpringBootApplication
@RefreshScope
@RestController
public class ConfigClientApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplication.class, args);
    }

    @Value("${git.value}")
    private String gitValue;

    @RequestMapping("/")
    public String git() {
        return gitValue;
    }
}
