mybatis中报错Could not find resource SqlMapConfig.xm

先展示解决方法，错误截图和报错信息在最后

一般常见的有两种错误
第一种：配置文件地址错误
第二种：代码以及配置文件路径均没有问题，但是却出现报错：
（整理）
原因：
一开始是因为默认的情况下，只有src是build path的source folder目录，因为你自己定义了一个文件夹，系统不会扫描你自己所定义的文件夹，需要手动的将自己定义的文件夹加载为source folder，参照上面的解决办法。

解决办法：右键点击SqlMapConfig.xml所在的文件夹(我的是config)------>Build Path------>Use as Source Folder

报错截图和代码展示java.io.IOException: Could not find resource SqlMapConfig.xml
