我们讨论了feign+hystrix在项目开发中,除了考虑正常的调用之外,负载均衡和故障转移也是关注的重点,这也是feign + ribbon+hystrix的优势所在,本节我们就讨论一下在feign中使用ribbon,有两种方式
一、通过在配置文件application.yml配置,开启ribbon,并指定调用生产者相对上一节可以不做任何更改,可以看项目(microservice-consumer-movie-feign-with-hystrix-hystrix-factory)
application.yml配置文件:
spring: application: name: microservice-consumer-movie-feign-with-hystrix-hystrix-factory server: port: 7901 eureka: client: healthcheck: enabled: true serviceUrl: defaultZone: http://jacky:admin@peer1:8761/eureka/,http://jacky:admin@peer2:8762/eureka/,http://jacky:admin@peer3:8763/eureka/ instance: prefer-ip-address: true microservice-provider-user: ribbon: NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 5000
二、通过通过写配置类,在启动类中指定ribbon配置类即可,可以看项目(microservice-consumer-movie-ribbon)了解springcloud架构可以加求求:三五三六二四七二五九
