<!--Hystrix依赖-->

2配置文件配置端口号

server:

    prot: 8899   # 端口号可以自行配置  只要是和别的服务的端口号不冲突就好

@SpringBootApplication

// 开启Dashboard

@EnableHystrixDashboard

public class DeptConsumerDashboard {

    public static void main(String[] args) {

        SpringApplication.run(DeptConsumerDashboard.class,args);

    }

}

添加监控注解

<!--actuator 完善监控信息 -->

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-actuator</artifactId>

</dependency>

//增加一个Servlet

    @Bean

    public ServletRegistrationBean hystrixMetricsStreamServlet(){

        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());

        //参数固定写法

        registrationBean.addUrlMappings("/actuator/hystrix.stream");

        return registrationBean;

    }
