3.编辑自定义文件

package com.bdsoft.utils;

import org.mybatis.generator.api.IntrospectedColumn;

    @Override
    public boolean validate(List<String> list) {
        return true;
    }

    /**
     * 为实体添加lombok的注解
     * @param topLevelClass
     * @param introspectedTable
     * @return
     */
    @Override
    public boolean modelBaseRecordClassGenerated(TopLevelClass topLevelClass, IntrospectedTable introspectedTable) {
        //添加domain的import

        topLevelClass.addJavaDocLine("/**");
        topLevelClass.addJavaDocLine("* Created by Mybatis Generator on " + date2Str(new Date()));
        topLevelClass.addJavaDocLine("*/");

        return true;
    }

            for (String remarkLine : remarkLines) {

            }
        }
        field.addJavaDocLine(" */");
        return true;

    }

    @Override
    public boolean modelSetterMethodGenerated(Method method, TopLevelClass topLevelClass, IntrospectedColumn introspectedColumn, IntrospectedTable introspectedTable, ModelClassType modelClassType) {

    }
}

4.配置启动文件

package com.bdsoft.utils;

/**
 * Created by hanyq on 2024/03/18.
 * 需要将mybatis-generator-config.xml文件中的targetProject地址以及数据库地址进行修改
 * 启动文件，只需要点击运行就行
 */
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.sql.SQLException;
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.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;

public class StartUp {
    public static void main(String[] args) throws URISyntaxException {
        try {
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            //直接获取generatorConfig.xml的文件路径 根据具体情况查看
            String genPath = System.getProperty("user.dir");
            String configAddress = genPath+"\\ws-common\\src\\main\\resources\\mybatis-generator-config.xml";
            File configFile = new File(configAddress);
            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);
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (InvalidConfigurationException e) {
            e.printStackTrace();
        } catch (XMLParserException e) {
            e.printStackTrace();
        }
    }
}

5.启动

注意文件地址，然后启动StartUp即可生成
