Generator automatically generates mybatis configuration and class information

When I use mybatis to write the ing between a class and a data table, there are too many column names in the table and there are also many problems. It is complicated to write the corresponding column names and Class Object Attributes one by one.

To facilitate and reduce errors, you can use the code generator provided by mybatis to automatically generate xml ing files, models, maps, and other information for mybatis.

Mybatis official website to download a mybatis-generator-core-1.3.2-bundle, In the compressed package find the jar package under Lib. Write mybatis. xml and execute it.

In cmd enter Java-jar mybatis-generator-core-1.3.2.jar-configfile generator. XML-overwrite, the path here is absolute, for convenience, we can create a BAT file in the folder where the mybatis-generator-core-1.3.2 is located, enter

TXT code

1. @ Echo off
2. Echo =========== mybatis starts to generate code ============================
3. Java-jar mybatis-generator-core-1.3.2.jar-configfile generator. XML-overwrite
4. Echo =========== mybatis code generation complete ============================

 

Finally, we can press shift and right-click to open the command window in the folder and directly run the BAT file.
