MybatisGenerator+lombok

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;

public class LombokPlugin extends PluginAdapter {

    @Override
    public boolean validate(List 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

/**
