springcloud5-断路器Dashboard监控仪表盘实战

7、断路器Dashboard监控仪表盘实战
    简介：讲解断路器Dashboard基础使用和查看
    1、加入依赖
         <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、启动类增加注解
        @EnableHystrixDashboard        
    3、配置文件增加endpoint
#暴露全部的监控信息
management:
  endpoints:
    web:
      exposure:
        include: "*"
    4、访问入口
        http://localhost:8781/hystrix

        Hystrix Dashboard输入： http://localhost:8781/actuator/hystrix.stream
