SpringCloud Config手动刷新及自动刷新

1、Config手动刷新
a、使用@RefreshScope注解

import org.springframework.beans.factory.annotation.Value; import org.springframework.cloud.context.config.annotation.RefreshScope; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; /** * 这边的@RefreshScope注解不能少，否则即使调用/refresh，配置也不会刷新 */ @RestController @RefreshScope public class ConfigClientController { @Value("${env}") private String env; @Value("${password}") private String password; @Value("${username}") private String username; @GetMapping("/config/profile") public String hello() { return this.env+","+this.password+","+this.username; } }

 

b、post请求config客户端的/refresh端点
http://localhost:6062/refresh

再次访问http://localhost:6062/config/profile，发现配置文件为最新配置。

2、Config自动刷新
1、WebHooks动态刷新

2、spring-cloud-bus动态刷新
