zuul整合hystrix实现网关监控(曾出现htstrix.stream显示404问题)
首先需要加入的依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId> </dependency>
启动需要加入的注解
package com.zuul; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard; import org.springframework.cloud.netflix.zuul.EnableZuulProxy; /** * @author yourheart * @Description * @create 2022-04-20 22:05 */ @SpringBootApplication //开启zuul注解 @EnableZuulProxy @EnableDiscoveryClient @EnableHystrixDashboard @EnableCircuitBreaker public class ZuulApplication { public static void main(String[] args) { SpringApplication.run(ZuulApplication.class,args); } }
配置文件
server: port: 1002 spring: application: name: zuul-service zuul: routes: product-service: path: /product-service/** serviceId: product-service prefix: /api eureka: client: service-url: defaultZone: http://localhost:8761/eureka/ management: endpoints: web: exposure: include: '*'
查看监控
http://127.0.0.1:1002/actuator
打开http://127.0.0.1:1002/actuator/hystrix.stream
打开http://127.0.0.1:1002/hystrix
在接口调用后
打印各个服务情况
