网上看了好多贴子都没解决我的问题 ,最后恶心的发现我竟然给eureka这个工程的pom文件打了pom 包,将pom打包方式删除问题解决. 不得不说是真的恶心

其他可能出现的问题
要加入这个

client:
    register-with-eureka: false   #是否将自己注册到eureka中
    fetch-registry: false         #是否从eureka中获取信息

最后附上我的application.yml代码

server:
  port: 7001
eureka:
  instance:
    hostname: 127.0.0.1
  client:
    register-with-eureka: false   #是否将自己注册到eureka中
    fetch-registry: false         #是否从eureka中获取信息
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
