一、Hystrix Dashboard 配置完成，并且可以运行。

二、服务提供者必须要依赖

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-hystrix</artifactId>
        <version>1.4.6.RELEASE</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>

三、服务提供者的启动类增加一个Bean

//启动类
    @SpringBootApplication
    @EnableEurekaClient //在服务启动后自动注册到Eureka
    @EnableDiscoveryClient //服务发现
    @EnableCircuitBreaker //开启熔断机制
    public class DeptProvider_8001 {
        public static void main(String[] args) {
            SpringApplication.run(DeptProvider_8001.class,args);
        }
    
        //增加一个Servlet，为了配合监控使用
        @Bean
        public ServletRegistrationBean getServlet(){
            ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
            registrationBean.addUrlMappings("/actuator/hystrix.stream");
            return registrationBean;
        }
    }

四、问题来了，通过URL访问了自己定义的服务之后，请求 [http://192.168.90.55:8001/actuator/hystrix.stream][http_192.168.90.55_8001_actuator_hystrix.stream] 仍然返回空，一直ping 无内容!!!

### 五、目前环境的解决办法是：**对自己的方法添加服务熔断机制** ###

再次运行，显示正常！
