4.1 Spring Cloud微服务入门之HystrixDashboard监控搭建

1. 新建cloud-consumer-hystrix-dashboard9001

2. 改POM

           
           <dependency>
               <groupId>org.springframework.cloudgroupId>
               <artifactId>spring-cloud-starter-netflix-hystrix-dashboardartifactId>
           dependency>
   
   

3. 改YML 给定一个端口号
   

4. 主启动加@EnableHystrixDashboard 开启监控功能

5. 所有Provider微服务提供类(8001,8002)都需要加监控依赖配置

   • 开启@EnableCircuitBreaker 熔断注解是必须的

   • 升级spring cloud H 版后有个bug 需要在被监控微服务主启动类下做如下配置

     /*
          * 此配置是为了服务监控配置，
          * */
         @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;
         }
     

6. 启动
