Introduction to mybaits aliases

typeAliases aliases　

1.1 Requirements

In mapper.xml, many statements are defined. The statement requires parameterType to specify the type of input parameters, and resultType to specify the mapping type of the output result.

 

If you enter the full path of the type when specifying the type, it is not convenient for development. You can define some aliases for the type specified by parameterType or resultType, and define the alias in mapper.xml to facilitate development.

1.2 mybatis supports aliases by default
