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();
        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
