SpringCloud Config手动刷新及自动刷新

1、Config手动刷新
a、使用@RefreshScope注解

1import org.springframework.beans.factory.annotation.Value;
2import org.springframework.cloud.context.config.annotation.RefreshScope;
3import org.springframework.web.bind.annotation.GetMapping;
4import org.springframework.web.bind.annotation.RestController;
5
6/**
7 * 这边的@RefreshScope注解不能少，否则即使调用/refresh，配置也不会刷新
8 */
9@RestController
10@RefreshScope
11public class ConfigClientController {
12
13    @Value("${env}")
14    private String env;
15    
16    @Value("${password}")
17    private String password;
18    
19    @Value("${username}")
20    private String username;
21
22    @GetMapping("/config/profile")
23    public String hello() {
24        return this.env+","+this.password+","+this.username;
25    }
26}

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
