SpringCloud-多个支付模块的Eureka集群(Day3)

我们上一篇已经演示了在Eureka集群下单个服务提供微服务的案例，我们这篇就演示多个服务提供的案例。我们复制cloud-provider-payment8001，并命名新的项目为cloud-provider-payment8002。

  
    cloud-provider-payment8001
    cloud-provider-payment8002
    cloud-consumer-order8080
    cloud-api-commons
    cloud-eureka-server7001
    cloud-eureka-server7002
    cloud-eureka-server7003
  

cloud-provider-payment8002

server:
  port: 8002

eureka:
  client:
    #表示是否将自己注册进Eurekaserver默认为true。
    register-with-eureka: true
    #是否从EurekaServer抓取已有的注册信息，默认为true。单节点无所谓，集群必须设置为true才能配合ribbon使用负载均衡
    fetchRegistry: true
    service-url:
      defaultZone: http://127.0.0.1:7001/eureka,http://localhost:7002/eureka,http://192.168.0.135:7003/eureka
