Hystrix Dashboard出现Unable to connect to Command Metric Stream

情况描述

feign项目添加hystrix dashboard监控面板,添加了一下依赖:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
</dependency>
           

运行项目出现Unable to connect to Command Metric Stream错误

原因

springboot 版本如果是2.0以上的dashboard的访问默认路径不是 “/hystrix.stream”,这就需要自己添加访问配置,修改访问路径,

只要在自己的项目里配置上下面的servlet就可以了

在启动类添加如下方法

添加访问路径

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