在写测试的时候发现报错了，一开始想的是Mybatis-plus是mybatis的增强工具，应该是两个都是需要引入的，百度了一番，后面发现有可能是是版本兼容的问题，对比了一下网上的例子发现别人的代码没有引入mybatis依赖，我删除了pom.xml的mybatis依赖，后面发现正常了。又踩了一个新手坑👍👍👍

总结：

依赖关系

MyBatis-Plus 是基于 MyBatis 的增强工具，它在 MyBatis 的基础上提供了更多的功能和便利性。因此，MyBatis-Plus 依赖于 MyBatis，当你在 pom.xml 中引入 MyBatis-Plus 时，它会自动引入 MyBatis 的核心依赖。

依赖传递

在 Maven 项目中，依赖是可以传递的。当你引入一个依赖时，它所依赖的其他库也会被自动引入。因此，当你在 pom.xml 中引入 MyBatis-Plus 时，MyBatis 的核心库也会被自动引入，不需要你手动再引入 MyBatis。
