Hystrix Stream的监控页面不显示内容

打开Hystrix Stream页面，进入后，发现只有一行Unable to connect to Command Metric Stream.

因为springboot的默认路径不是 "/hystrix.stream"，在启动类中加入如下代码

@Bean
public ServletRegistrationBean getServlet() {
HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
registrationBean.setLoadOnStartup(1);
registrationBean.addUrlMappings("/hystrix.stream");
registrationBean.setName("HystrixMetricsStreamServlet");
return registrationBean;
}

重启项目，并重新打开监控页面，访问一下即可就可以了
