FreeMarker 生成Java、mybatis文件

                                             FreeMarker 生成Java、mybatis文件

       将mysql数据库表通过FreeMarker生成对应的Java文件和对应的mybatis文件。

       FreeMarker是一款模板引擎： 即一种基于模板和要改变的数据， 并用来生成输出文本（HTML网页、电子邮件、配置文件、源代码等）的通用工具。 它不是面向最终用户的，而是一个Java类库，是一款程序员可以嵌入他们所开发产品的组件。

       FreeMarker是免费的，基于Apache许可证2.0版本发布。其模板编写为FreeMarker Template Language（FTL），属于简单、专用的语言。需要准备数据在真实编程语言中来显示，比如数据库查询和业务运算， 之后模板显示已经准备好的数据。在模板中，主要用于如何展现数据， 而在模板之外注意于要展示什么数据。
