如果host文件里边加入

就可以用了

配置文件如下

spring:
  application:
    name: order
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
  #instance:
    hostname: order
    #instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}
    #prefer-ip-address: true
server:
  port: 8018


ribbon:
  ReadTimeout: 120000
  ConnectTimeout: 30000
  #eureka:
    #enabled: true

#PRODUCTE:
  #ribbon:
    #NIWSServerListClassName: com.netflix.loadbalancer.RandomRule
    #listOfServers: http://localhost:8019

这样需要咋解决师兄
