spring-cloud-config's Introduction

##依次启动eureka-server、confg-cserver,启动两个config-client,端口为:8881。

访问[http://localhost:8881/hi]浏览器显示: foo version 3

这时我们去代码仓库将foo的值改为“foo version 4”,即改变配置文件foo的值。

如果是传统的做法,需要重启服务,才能达到配置文件的更新。

此时,我们只需要发送post请求:http://localhost:8881/actuator/bus-refresh,你会发现config-client会重新读取配置文件

重新读取配置文件:这时我们再访问http://localhost:8881/hi 或者http://localhost:8882/hi 浏览器显示:

foo version 4

另外,/actuator/bus-refresh接口可以指定服务,即使用”destination”参数,

比如 “/actuator/bus-refresh?destination=customers:**” 即刷新服务名为customers的所有服务。
