由于 hystrix 对流量的监控状态的监控是单应用的。有的时候我们需要全面查看整个系统的监控状态，那么我们可能需要引入turbine 的监控检查。在spring boot admin 已经有spring-boot-admin-server-ui-turbine 这个插件
turbine 是一个hystrix 的集合。里面展示所有的hystrix的效果。我们这里用的spring cloud的版本是
<spring-boot.version>1.5.3.RELEASE</spring-boot.version> <spring-cloud.version>Dalston.SR1</spring-cloud.version> <spring-boot-admin.version>1.5.0</spring-boot-admin.version>
1、配置turbine 的包依赖
<dependencies> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server</artifactId> <version>${spring-boot-admin.version}</version> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server-ui</artifactId> <version>${spring-boot-admin.version}</version> </dependency> <dependency> <groupId>de.codecentric</groupId> <artifactId>spring-boot-admin-server-ui-turbine</artifactId> <version>${spring-boot-admin.version}</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-mail</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-turbine</artifactId> </dependency> </dependencies> 2、配置启动类
@SpringBootApplication @EnableAdminServer @EnableDiscoveryClient @EnableTurbine open class YkbBootAdminServerApplication { companion object { @JvmStatic fun main(args: Array<String>) { SpringApplication.run(YkbBootAdminServerApplication::class.java, *args) } } }
启动类配置了@EnableTurbine
3、配置启动项：（application.properties）
spring.boot.admin.routes.endpoints= env,metrics,trace,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream,turbine.stream spring.boot.admin.turbine.location=TGS-SPRING-BOOT-ADMIN management.security.enabled=false security.basic.enabled=false turbine.clusterNameExpression=new String("default") turbine.appConfig=YKB-ACCOUNT-MOBILE turbine.combineHostPort=true
其中endpoints 配置hystrix.stream,turbine.stream
配置了spring.boot.admin.turbine.location=TGS-SPRING-BOOT-ADMIN
代表是由TGS-SRPING-BOOT-ADMIN实例来管理所有的监控
最后
turbine.appConfig=YKB-ACCOUNT-MOBILE代表你可以监控的应用有哪些，可以用逗号隔开
4、配置hystrix
ykb-account-mobile 配置熔断机制 这里采用 @SpringCloudApplication里面包含了熔断机制
@SpringCloudApplication @EnableZuulProxy @EnableFeignClients open class AccountMobileApplication { @LoadBalanced @Bean open fun restTemplate(): RestTemplate { return RestTemplate() } companion object { @JvmStatic fun main(args: Array<String>) { SpringApplication.run(AccountMobileApplication::class.java, *args) } } } 需要引入的jar包为 <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-hystrix</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-eureka</artifactId> </dependency><dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-zuul</artifactId> </dependency> 其中application的配置为 server.port=7180 management.port=7181 eureka.instance.prefer-ip-address = true eureka.instance.lease-renewal-interval-in-seconds=10 eureka.instance.lease-expiration-duration-in-seconds=30 eureka.client.service-url.defaultZone= http://eureka.ejuda.net:8761/eureka/ eureka.client.fetch-registry=true eureka.instance.metadata-map.management.port= ${management.port} 其中 eureka.instance.metadata-map.management.port = ${ management.port }
是必须的。因为管理端口跟服务端口不一样
