            <dependency>

            <dependency>

        </dependencies>
    </project>

2.添加bootstrap.yml和application.yml

application.yml:
    
    # 端口
    server:
      port: 8001
    
    spring:
      application:
        # 应用名称
        name: def
    
    
    bootstrap.yml
    
    spring:
      cloud:
        config:
          # 仓库地址
          uri: http://127.0.0.1:7788
          # 对应 {label} 部分，即 Git 的分支
          label: master
          # 对应 {application} 部分
          name: def
          # 对应 {profile} 部分
          profile: dev
    management:
      endpoints:
        web:
          exposure:
            include: refresh,health

3.在控制器里通过注解引入属性，@Refresh属性用来手动刷新同步config server的数据

@RefreshScope
    @RestController
    public class TestController {
        @Value("${zhuzhi}")
        private String str;
        @RequestMapping("/test")
        public String getProperties(){
            return str;
        }
    }

4.要想刷新数据，需要发送post请求到client地址：  
http://localhost:8001/actuator/refresh
