springboot2.0 springcloud 断路器仪表盘支持

springboot 1.5 的时候  springcloud 添加 断路器仪表盘  按照网上的方法是没有问题的  但是 springboot2.0的时候一直无法连接  

所以需要添加

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