springcloud 找不到@EnableEurekaServer注解

1.背景

springcloud是基于springboot的，所以我想建一个项目，该项目父项目为spirngboot项目，版本是2.1.4.RELEASE，然后加入springcloud相关的依赖，这样就不需要在各个子项目中进行重复的引入依赖。

2.问题

在搭建注册中心时，找不到@EnableEurekaServer 注解.刚开始，我认为可能是springcloud和springboot的版本不匹配导致的，通过别的博客发现不是这个问题，最终发现是在子项目中依赖引入错误

3.解决方法

方框内的才是正确的坐标,希望解决你的问题。
