SpringCloud------断路器Dashboard监控仪表盘

Posted 2021-03-05 玉天恒

前提：

配置了熔断或者Feign降级的接口才会显示在仪表盘

断路器原理：

 

 

 

1.添加依赖

<!-- 仪表盘监控 -->
<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.添加启动类注解@EnableHystrixDashboard

import org.mybatis.spring.annotation.MapperScan;
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;

@SpringBootApplication
@MapperScan("cn.ytheng.order_service")
@EnableFeignClients
@EnableCircuitBreaker
@EnableHystrixDashboard
public class OrderServiceApplication {


    public static void main(String[] args) {

        SpringApplication.run(OrderServiceApplication.class, args);
    }

}

 

3.修改application.yml配置

server:
  port: 8781

#暴露全部的监控信息
management:
  endpoints:
    web:
      exposure:
        include: "*"

 

4.访问地址

http://localhost:8781/hystrix

http://localhost:8781/actuator/hystrix.stream  （可直接访问，会采集接口的信息）(SSE：server-send-event推送信息到前端)

1）

 2）
