刷新配置
在bootstrap.yml添加如下配置，暴露/actuator/refresh 端点：

# 暴露监控端点
management:
  endpoints:
    web:
      exposure:
        include: '*'

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;
  }
}

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:8082/actuator/refresh
