Problem phenomenon:
I encountered a bug in the project before, and the error was reported as follows:
org.ibatis.binding.BindingException: Invalid bound statement (not found): com.xxxxxxxxx.mappers.xxxMapper
problem analysis:

Mybatis binding exception: Cannot find the xxxMapper.xml file corresponding to this xxxMapper interface.

Solution:
Ensure that the two files have the same name:
