###服务启动端口号
server:
  port: 8001
###服务名称(服务注册到eureka名称)  
spring:
    application:
        name: Use
    cloud: 
      client: 
        ipAddress: 127.0.0.1
###服务注册到eureka地址  
eureka:
  client:
    service-url:
           defaultZone: http://localhost:8100/eureka
    #注册
    register-with-eureka: true
    ###是否需要从eureka上获取注册信息
    fetch-registry: true
  instance: 
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ipAddress}:${spring.application.name}:${server.port}
