Unable to connect to Command Metric Stream.使用Hystrix-dashboard监控不到状态数据问题（springBoot2.x以上版本）

springBoot2.x以上的配置发生了变化，需要添加一个配置类，才能监控到状态数据。

1、要想使用Hystrix-dashboard，需要导入依赖的启动器

 <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-hystrix -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        
        <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-hystrix-dashboard -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

2、添加一个配置类，必须的，否则无法监控

@Configuration
public class ConfigBean {

    @Bean
    public ServletRegistrationBean<HystrixMetricsStreamServlet> getServlet() {
        HystrixMetricsStreamServlet servlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean<HystrixMetricsStreamServlet> bean = new ServletRegistrationBean<>(servlet);
        bean.addUrlMappings("/hystrix.stream");
        bean.setName("HystrixMetricsStreamServlet");
        return bean;
    }
}

3、修改启动类

@SpringBootApplication
@EnableEurekaClient
@EnableCircuitBreaker   //开启熔断器，断路器，默认不开启
@EnableHystrixDashboard
@EnableHystrix
public class SpringcloudEurekaConumerRibbonHystrixApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringcloudEurekaConumerRibbonHystrixApplication.class, args);
    }
}

4、启动项目，访问http://localhost:9010/hystrix（测试项目在本地，所以ip为localhost）
