SpringCloud之集成配置中心及自动刷新

环境：SpingBoot2.0 ，SpringCloud Finchley.RELEASE

 

 登陆github建立一个仓库 myspringcloudconfig 而后再建立一个config-client1文件夹

编写application.yml

name: zhangsan

application-dev.yml

name: zhangsan-dev

application-test.yml

name: zhangsan-test

 

3个文件并上传到config-client1目录下

 

搭建rabbitmq服务器

省略...

 

搭建Config Server项目 取名 zns-config

@RefreshScope加在须要读取配置的类上

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

 

测试

1.启动rabbitmq

2.启动注册中心eureka

3.启动配置中心项目

4.启动配置客户端项目

 

访问 getName 控制器url，能够看到已经读取到了git上dev环境的name属性值

 

git上修改name的值保存提交，再调用配置中心服务刷新配置url  

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

 

客户端再次访问getName,能够看到name的最新值已经同步更新显示
