server:
  port: 7001

eureka:
  instance:                   #定义Eureka实例
    hostname: locahost #Eureka实例所在的主机名

  #eureka默认情况下,把自己当做客户端来注册自己,所以我们要禁用它
  client:
    register-with-eureka: false #表示是否将自己注册到Eureka Server上，默认为true
    fetch-registry: false #表示是否从Eureka Server上获取注册信息，默认为true
    service-url:
      defaultZone: http://locahost:${server.port}/eureka/
