前言

最近项目中用到了

Mybatis

的通用代码生成器

mybatis-generator

，记起之前记录过的一篇文章mybatis 生成代码配置 mybatis-generator:generate 的使用详解，用的是同一套东西，只是对比起之前添了一点东西

1、开发工具Eclipse -> Idea2、添加Lombok模块3、模块配置

之前的博客名也改为了

SpringBoot - 集成 MyBatis 通用代码生成器 mybatis-generator（Eclipse篇）

，新旧实现，有需要的可对比看看

环境

Mysql + IDEA

SpringBoot2.5.4 + Mybatis2.1.5

具体实现

注：nullCatalogMeansCurrent=true是避免

Mybatis Generator

生成文件的时使用

Mysql

数据库的同名数据表

运行

• Maven-》项目-》Plugins-》mybatis-generator

  下双击运行即可

• 控制台日志

• 生成代码如下
