关于class path resource [mapper/*Mapper.xml] cannot be opened because it does no exists异常的一些记录

这是用springboot整合mybatis时遇到的一个小问题，问题虽小，但是也耽误了很多时间，搜了很多博客，但大多都是复制粘贴的废话，说不到点子上，最终花了蛮久才找到一个有用的。特此记录一下。

关于问题：

问题讲的是mapper文件不存在，那要么就是你真的没有这个文件，要么就是application.properties(或者application.yaml)配置出错了。我就是配置文件写错了。。。

我之前写的，这样找不到xml文件内：

mybatis.config-location=classpath:mapper/*Mapper.xml

要用下面这样就可以了：

mybatis.mapper-locations=classpath:mapper/*Mapper.xml
