以后，才会进行项目开发，而不是一上来就写代码，跟无头苍蝇一样。\u003C\u002Fp>\n\u003Cp>等表设计确立以后，就可以用到本文要讲的代码生成器了，它能根据表自动生成实体类、 \u003Ccode>Controler\u003C\u002Fcode> 类、\u003Ccode>Service\u003C\u002Fcode> 类、\u003Ccode>Mapper\u003C\u002Fcode> 接口等模板代码，偷懒工具无疑了。\u003C\u002Fp>\n\u003Cp>接下来，我们看看要怎么使用它。\u003C\u002Fp>\n\u003Ch2 id=\"toc-1\">添加依赖\u003C\u002Fh2>\n\u003Cp>首先，添加代码生成器的 Maven 依赖以及
