开发的时候在想如果自己做项目经理，如何从零搭建一套框架呢？就着手实践和记录了一下。这一篇主要介绍一下hystrix和hystrix Dashboard的使用。hystrix是springcloud的断路器，结合上篇讲的feign的fallback使用。详细的理论知识可以自行搜索学习。本篇主要介绍在项目实战使用。本篇以原来创建的example-web项目为基础，在里面加入hystrix，可以看到对接口请求的请求响应时间, 请求成功率等数据。

1，引入hystrix和hystrix Dashboard依赖包。

2，启动类上加上启动注解。springboot 版本如果是2.0则需要添加 ServletRegistrationBean 因为springboot的默认路径不是 "/hystrix.stream"，要在自己的项目里配置servlet。

3，启动example-eureka和example-web两个项目。

4，访问http://localhost:8787/hystrix/

5，在url处输入http://localhost:8787/hystrix.stream。并点击monitor stream。

6，没有请求的时候一直在显示loading。

7，用postman向example-web发送一个请求过来。就可以看到详细信息了。

8，网上的图介绍一下仪表盘的意思。

下一篇在example-wen项目中加turbine。
