      defaultZone: http://${eureka-server.user}:${eureka-server.password}@${eureka-server.host}/eureka/
  instance:

spring-boot 2.X

eureka:
  client:
    fetch-registry: true
    service-url:
      defaultZone: http://${eureka-server.user}:${eureka-server.password}@${eureka-server.host}/eureka/
  instance:
    appname: data-main-api
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    # 不加此项 如果注册中心 和 服务位于同一服务器，会导致 注册的ip为 localhost，导致其他 地址 无法访问此 服务
    prefer-ip-address: true
    ip-address: ${spring.cloud.client.ip-address}
