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
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。
