配置刷新三要素

spring-boot-starter-actuator
/actuator/refresh

management:
  endpoints:
    web:
      exposure:
        include: refresh

待刷新的配置属性所在的类上添加了 @RefreshScope 注解 ，例如： 

@RestController
@RefreshScope
public class ConfigClientController {
  @Value("${profile}")
  private String profile;

  @GetMapping("/profile")
  public String hello() {
    return this.profile;
  }
}

这样，修改 profile 配置后，只需向应用的 /actuator/refresh 端点发送POST请求，即可刷新该属性。例如： 

curl -X POST http://localhost:8081/actuator/refresh

自动刷新、批量刷新-Spring Cloud Bus

参考文档： http://www.itmuch.com/spring-cloud/spring-cloud-bus-auto-refresh-configuration/

引入Cloud Bus后，就会多一个 /actuator/bus-refresh 端点。
