如何配置：断路器Dashboard监控仪表盘

断路器Dashboard监控仪表盘：如图

这个东西是怎么配置和访问的呢？

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

package net.xdclass.order_service;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
@EnableFeignClients
@EnableCircuitBreaker
@EnableHystrixDashboard
public class OrderServiceApplication {

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

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }


}

3、配置文件增加endpoint
management:
  endpoints:
    web:
      exposure:
        include: "*"

server:
  port: 8781


#指定注册中心地址
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

#服务的名称
spring:
  application:
    name: order-service
  redis:
    database: 0
    host: 127.0.0.1
    port: 6379
    timeout: 2000

#自定义负载均衡策略
product-service:
  ribbon:
    NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule


#修改调用超时时间
feign:
  hystrix:
    enabled: true
  client:
    config:
      default:
        connectTimeout: 4000
        readTimeout: 4000

#把hystrix超时时间禁用
#hystrix:
#  command:
#    default:
#      execution:
#        timeout:
#          enabled: false

#execution.isolation.thread.timeoutInMilliseconds=4000

#设置超时时间
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 1000
            
#断路器Dashboard监控仪表盘
management:
  endpoints:
    web:
      exposure:
        include: "*"

4、访问入口
        http://localhost:8781/hystrix
        Hystrix Dashboard输入： http://localhost:8781/actuator/hystrix.stream
