SpringCloud断路器监控(Hystrix + Turbine)

在父工程目录下创建一个maven项目，在这个maven项目中添加依赖

  1. <dependencies>
  2.         <dependency>
  3.             <groupId>org.springframework.cloud</groupId>
  4.             <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
  5.         </dependency>
  6.         <dependency>
  7.             <groupId>org.springframework.boot</groupId>
  8.             <artifactId>spring-boot-starter-web</artifactId>
  9.         </dependency>
  10.         <dependency>
  11.             <groupId>org.springframework.boot</groupId>
  12.             <artifactId>spring-boot-starter-actuator</artifactId>
  13.         </dependency>
  14.         <dependency>
  15.             <groupId>org.springframework.cloud</groupId>
  16.             <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
  17.         </dependency>
  18.         <dependency>
  19.             <groupId>org.springframework.cloud</groupId>
  20.             <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
  21.         </dependency>
  23.         <dependency>
  24.             <groupId>org.springframework.cloud</groupId>
  25.             <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
  26.         </dependency>
  27.     </dependencies>

在配置文件application.yml中添加以下配置

  1. server:
  2.   port: 9999
  4. spring:
  5.   application:
  6.     name: monitor
  8. eureka:
  9.   client:
  10.     serviceUrl:
  11.       defaultZone: http://localhost:7010/eureka/
  13. #http://localhost:9999/hystrix  http://localhost:8777/actuator/hystrix.stream
  14. management:
  15.   endpoints:
  16.     web:
  17.       exposure:
  18.         include: "*"
  19.       cors:
  20.         allowed-origins: "*"
  21.         allowed-methods: "*"
  23. turbine:
  24. #  需要监控的服务名称
  25.   app-config: ribbon-service
  26.   aggregator:
  27.     clusterConfig: default
  28.   clusterNameExpression: new String("default")
  29.   combine-host: true
  30.   instanceUrlSuffix:
  31.     default: actuator/hystrix.stream

启动类

  1. @SpringBootApplication
  2. @EnableEurekaClient
  3. @EnableDiscoveryClient
  4. @RestController
  5. @EnableHystrix
  6. @EnableHystrixDashboard
  7. @EnableCircuitBreaker
  8. @EnableTurbine
  9. public class MonitorApplication {
  10.     public static void main(String[] args) {
  11.         SpringApplication.run( MonitorApplication.class, args );
  12.     }
  13. }

依次启动Eureka、config-server、server02、ribbon-service、feign-service、zuul、还有本服务

在浏览器上访问http://localhost:9999/hystrix
