先继承Mybatis的插件适配器, 写一个自己的插件

package org.mybatis.generator.plugins;
    
    import org.mybatis.generator.api.IntrospectedColumn;
    import org.mybatis.generator.api.IntrospectedTable;
    import org.mybatis.generator.api.PluginAdapter;
    import org.mybatis.generator.api.dom.java.Interface;
    import org.mybatis.generator.api.dom.java.Method;
    import org.mybatis.generator.api.dom.java.TopLevelClass;
    
    import java.text.SimpleDateFormat;
    import java.util.Date;
    import java.util.List;
    
    /**
     * @author Liweizhou  2018/6/6
     */
    public class LombokPlugin extends PluginAdapter {
    
        @Override
        public boolean validate(List<String> list) {
            return true;
        }
    
        @Override
        public boolean modelBaseRecordClassGenerated(TopLevelClass topLevelClass, IntrospectedTable introspectedTable) {
            //添加domain的import
            topLevelClass.addImportedType("lombok.Data");
            topLevelClass.addImportedType("lombok.Builder");
            topLevelClass.addImportedType("lombok.NoArgsConstructor");
            topLevelClass.addImportedType("lombok.AllArgsConstructor");
    
            //添加domain的注解
            topLevelClass.addAnnotation("@Data");
            topLevelClass.addAnnotation("@Builder");
            topLevelClass.addAnnotation("@NoArgsConstructor");
            topLevelClass.addAnnotation("@AllArgsConstructor");
    
            //添加domain的注释
            topLevelClass.addJavaDocLine("/**");
            topLevelClass.addJavaDocLine("* Created by Mybatis Generator on " + date2Str(new Date()));
            topLevelClass.addJavaDocLine("*/");
    
            return true;
        }
    
        @Override
        public boolean clientGenerated(Interface interfaze, TopLevelClass topLevelClass, IntrospectedTable introspectedTable) {
            //Mapper文件的注释
            interfaze.addJavaDocLine("/**");
            interfaze.addJavaDocLine("* Created by Mybatis Generator on " + date2Str(new Date()));
            interfaze.addJavaDocLine("*/");
            return true;
        }
    
        @Override
        public boolean modelSetterMethodGenerated(Method method, TopLevelClass topLevelClass, IntrospectedColumn introspectedColumn, IntrospectedTable introspectedTable, ModelClassType modelClassType) {
            //不生成getter
            return false;
        }
    
        @Override
        public boolean modelGetterMethodGenerated(Method method, TopLevelClass topLevelClass, IntrospectedColumn introspectedColumn, IntrospectedTable introspectedTable, ModelClassType modelClassType) {
            //不生成setter
            return false;
        }
    
        private String date2Str(Date date) {
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
            return sdf.format(date);
        }
    }

首先在本机编译这份java文件, 生成的字节码文件(.class), 先到maven仓库的这个目录

org\\mybatis\\generator\\mybatis-generator-core\\1.3.5 (版本无所谓, 根据自己情况修改)  
找到这个mybatis-generator-core-1.3.5.jar文件  
把字节码塞到 jar包对应的包文件夹下面

mybatis-generator.xml大概如下: 留意标签的位置
