springboot 2.0 + spring cloud + hystrix dashboard

springcloud整合hystrix dashboard，打开界面报了不能连接 Unable to connect to Command Metric Stream.，现在整理下几种解决方法：

1. 配置文件暴露端口，填写hystrix地址时，按照single hystrix提示的填写即可

management:
  endpoints:
    web:
      exposure:
        include: "*"

2. 注入Bean，并且访问hystrix地址时，去掉actuator

@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;
	}
