【SSM框架】使用MyBatis Generator自动创建代码

今天学习ssm框架搭建，发现mybatis Generator自动穿件代码，实现，成功，在此做笔记，备份

• 开发工具用的是IDEA

• maven项目

---

• 项目结构
  

• 使用IDEA创建maven javaWeb项目，请自行百度

• maven配置

• 至此，项目是搭建完毕了，接下来就只是运行句简单的代码就可以实现了
  

再IDEA右侧Maven projects窗口中，点击Execute Maven Goal按钮，再Gommand line输入框中输入 mybatis-generator:generate -Dmybatis.generator.overwrite=true 点击 Excute按钮即可，直接看图：

接下来就可以进行后续的工作了……
