MyBatis automatic generation of entity classes, DAO interfaces, and Mapping mapping files

Since MyBatis is a semi-automatic ORM framework, its work is mainly to configure the mapping mapping file, in order to reduce manual mapping file, you can use the MyBatis generator, automatically generate entity class, DAO interface and its mapping file, And then copy directly to the project to make a slight modification can be used directly.

The generator directory is as follows:

First go to the Lib folder, the directory is as follows:

Main changes Generatorconfig.xml

Note that the table needs to be created in a specific database now, and then shift+ the right mouse button in the Lib folder to open the console command input:

Java-jar Mybatis-generator-core-1.3.2.jar-configfile Generatorconfig.xml-overwrite

This allows you to see the code for the developed directory in SRC.
