Eureka启动报错

Eureka服务启动报错，这是比较常见的错误，对于新手总是会出现各种各样的问题导致报错，但是导致这种问题出现的原因让我简直要吐血，是因为我在pom.xml中设置了打包方式。
报错如下：

applicotion.yml文件改了一遍又一遍
如下：

server:
  port: 7001 # Eureka端口号
spring:
  application:
    name: eureak #服务名称
eureka:
  instance:
    hostname: localhost
  client:
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port} #eureka服务端地址端口
    fetch-registry: false #是否从eureka中获取服务信息
    register-with-eureka: false #是否将自己注册到Eureka中

最后搞来搞去发现是在pom.xml中设置了打包方式为pom
