近期在springboot整合Mybatis和Thymeleaf模板的过程中出了一个小错误。

学过mybatis的同学都知道，mapper接口和mapper.xml要在一个目录下面

 本人由于在操作的过程很懒 复制了很多东西 所以就出现了下面这个错误。

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.javaee_3.mapper.CourseMapper.getAll

尝试了网上诸多办法 还是不行，于是我使用下面的办法：

①把resources下 com.javaee_3.mapper 目录先删除

②一步步重新创建目录文件，新建com，新建javaee_3，新建mapper，然后再把CourseMapper.xml加入子目录

③在maven插件那里clean 然后再重新运行。

④查看target 文件， 看两文件是否打包在一个文件夹。

到这步 ，应该就没什么大问题咯~

下面分享一下我在Springboot整合mybatis和Thymeleaf模板的maven文件
