当时报错也是一脸茫然，然后在网上进行查找，参考了许多博客，找出是Spring Boot 和 Spring Cloud的版本不对应！！

贴出Spring Cloud官网上所给出的Spring Boot 和 Spring Cloud的对应版本。
可能时间久了 出新版本了，到时候自行在官网上查找！！！
在官网上哪里找呢？
进入Spring Cloud官网 什么也不用点，Ctrl+F 搜索 Boot Version 就可以找到。如图

在这里插入图片描述

解决的方法
提高springcloud的版本，
我的把G版本换为H版本就可以成功运行了
在这里插入图片描述
也可以降低springboot的版本

总之就是把版本对应着！！！
