# 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

<dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <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>
    
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
            </dependency>
        </dependencies>

在配置文件application.yml中添加以下配置

server:
      port: 9999
    
    spring:
      application:
        name: monitor
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:7010/eureka/
    
    #http://localhost:9999/hystrix  http://localhost:8777/actuator/hystrix.stream
    management:
      endpoints:
        web:
          exposure:
            include: "*"
          cors:
            allowed-origins: "*"
            allowed-methods: "*"
    
    turbine:
    #  需要监控的服务名称
      app-config: ribbon-service
      aggregator:
        clusterConfig: default
      clusterNameExpression: new String("default")
      combine-host: true
      instanceUrlSuffix:
        default: actuator/hystrix.stream

启动类

@SpringBootApplication
    @EnableEurekaClient
    @EnableDiscoveryClient
    @RestController
    @EnableHystrix
    @EnableHystrixDashboard
    @EnableCircuitBreaker
    @EnableTurbine
    public class MonitorApplication {
        public static void main(String[] args) {
            SpringApplication.run( MonitorApplication.class, args );
        }
    }

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][http_localhost_9999_hystrix]

在第一栏填入

http://localhost:8777/actuator/hystrix.stream或http://localhost:9999/turbine.stream

出现以下界面
