SpringCloud之集成配置中心及自動刷新

環境：SpingBoot2.0 ，SpringCloud Finchley.RELEASE

 

 登陸github建立一個倉庫 myspringcloudconfig 而後再建立一個config-client1文件夾

編寫application.yml

name: zhangsan

application-dev.yml

name: zhangsan-dev

application-test.yml

name: zhangsan-test

 

3個文件並上傳到config-client1目錄下

 

搭建rabbitmq服務器

省略...

 

搭建Config Server項目 取名 zns-config

 搭建Config Client項目 取名 zns-config-client

bootstrap.yml

@RefreshScope加在須要讀取配置的類上

@RestController @RefreshScope public class MyController { @Value("${name}") String name; @RequestMapping("/getName") public String getName(){ return name; } }

 

測試

1.啓動rabbitmq

2.啓動註冊中心eureka

3.啓動配置中心項目

4.啓動配置客戶端項目

 

訪問 getName 控制器url，能夠看到已經讀取到了git上dev環境的name屬性值

 

git上修改name的值保存提交，再調用配置中心服務刷新配置url  

http://localhost:10005/actuator/bus-refresh

 

客戶端再次訪問getName,能夠看到name的最新值已經同步更新顯示
