springboot: Unable to connect to Command Metric Stream.

基本配置，像jar包，注解都是没问题的，但是在进入控制台后，报错。

解决：加个bean

@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;
}
