    fetch-registry: true
    service-url:
      defaultZone: http://${eureka-server.user}:${eureka-server.password}@${eureka-server.host}/eureka/
  instance:
    appname: data-main-api
    instance-id: ${spring.cloud.client.ipAddress}:${server.port}

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}
    # 不加此項 如果注冊中心 和 服務位於同一服務器，會導致 注冊的ip為 localhost，導致其他 地址 無法訪問此 服務
    prefer-ip-address: true
    ip-address: ${spring.cloud.client.ip-address}
