二、异常原因

一般的原因是Mapper interface和xml文件的定义对应不上，

需要检查包名，namespace，函数名称等能否对应上，

需要比较细致的对比，我经常就是写错了一两个字母搞的很长时间找不到错误

三、异常解决过程

1.常见解决方法

出现这个错误时，按以下步骤检查一般就会解决问题：

1：检查xml文件所在的package名称是否和interface对应的package名称一一对应

2：检查xml文件的namespace是否和xml文件的package名称一一对应

3：检查函数名称能否对应上

4：去掉xml文件中的中文注释

5：随意在xml文件中加一个空格或者空行然后保存

一般来说到此就可以排除错误了
