第112天学习打卡（SpringCloud Feign:使用接口方式调用服务 Hystrix Dashboard） (6)

修改springcloud-consumer-dept-feign的application.yml

server: port: 80 # 开启降级feign.hystrix feign: hystrix: enabled: true # Eureka配置 eureka: client: register-with-eureka: false # 不向Eureka 注册自己 service-url: defaultZone: :7001/eureka/,:7002/eureka/,:7003/eureka/

服务降级在客户端 服务熔断在服务端

**测试：先启动7001 然后启动8001（springcloud-proviser-sept-8001） ,80(springcloud-consumer-dept-feign),然后在把8001停掉 **

测试结果：

Hystrix: Dashboard 流监控 springcloud-consumer-hystrix-dashboard

application.yml

server: port: 9001

DeptConsumerDashboard_9001.java

package com.kuang.springcloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard; @SpringBootApplication @EnableHystrixDashboard //开启监控页面 public class DeptConsumerDashboard_9001 { public static void main(String[] args){ SpringApplication.run(DeptConsumerDashboard_9001.class,args); } }

springclou-provider-dept-hystrix-8001 修改 DeptProviderHystrix.java

package com.kuang.springcloud; //启动类 import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; import org.springframework.context.annotation.Bean; @SpringBootApplication @EnableEurekaClient//在服务启动后自动注册到Eureka中 @EnableDiscoveryClient //服务发现 @EnableCircuitBreaker //添加对熔断的支持 public class DeptProviderHystrix_8001 { public static void main(String[] args){ SpringApplication.run(DeptProviderHystrix_8001.class,args); } //增加一个Servlet @Bean public ServletRegistrationBean hystrixMetricsStreamServlet(){ ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet()); registrationBean.addUrlMappings("/actuator/hystrix.stream");//访问这个页面就可以被监控了 return registrationBean; } }

先启动7001 端口 再启动9001端口 然后启动DeptProviderHystrix_8001端口
