简介
在上一节中,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)
项目结构如下:
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)
项目结构如下:
