JFinal使用技巧-Enjoy魔板代码生成器

^_^ 搞事情~ 要趁早!   demo生成器还不能满足你? 需要service 需要 Controller吗?

再放个页面的吧 , 比较有代表性

</div>
#("#")end

#("#")define css()

#("#")end

#("#")define js()

    <script type="text/javascript">

这个功能包建在外面, 再Build Path进去, 算是可插拔哦~

此外模板文件可以与项目一起打包在 jar 之中，用一下 Enjoy 3.2 的这个用法：
engine.setSourceFactory(new ClassPathSourceFactory())

这个配置可以让你的程序去 class path 与 jar 包之中去找模板文件，十分的爽
