Where to modify:

Javamodelgenerator, generate the position of the PO class
Location of Sqlmapgenerator,mapper Map file generation
Where the Javaclientgenerator,mapper interface is built
Table, whose TableName property corresponds to the corresponding tables in the database

Create a new Generator.java file under the SRC package

Import Java.io.File;
Import java.util.ArrayList;

Import java.util.List;
Import Org.mybatis.generator.api.MyBatisGenerator;
Import org.mybatis.generator.config.Configuration;
Import Org.mybatis.generator.config.xml.ConfigurationParser;

Import Org.mybatis.generator.internal.DefaultShellCallback; public class Generatorsqlmap {public void Generator () throws exception{list<string> warnings = new A
        Rraylist<string> ();
        Boolean overwrite = true;
        Specifies the reverse engineering profile file ConfigFile = new file ("Src/generatorconfig.xml");
        Configurationparser cp = new Configurationparser (warnings);
        Configuration config = cp.parseconfiguration (configfile);
        Defaultshellcallback callback = new Defaultshellcallback (overwrite);
        Mybatisgenerator mybatisgenerator = new Mybatisgenerator (config, callback, warnings);

    Mybatisgenerator.generate (NULL);
     public static void Main (string[] args) throws Exception {   try {generatorsqlmap generatorsqlmap = new Generatorsqlmap ();

You can create a new project to generate this PO, DAO, Mapper

The specific methods are as follows:
