Jfinal自动生成带setter和getter等常用方法的Model文件方案
Jfinal的数据操作方式是get与set,但是要记住表名与字段名。笔者自己写了个Model生成工具：
1.自动生成类似JavaBean的setter与getter,免除了需要记住数据库结构与不能通过“.”来快速设置的麻烦。
2.自动生成批量插入数据new Model(xxxxxx);
3.自动生成批量修改数据setData(xxxxx);
4.生成一个分页方法，返回类型为Map可直接renderJson(Map);方法内提供一个where查询参数对，不需要设置为null即可（详细看程序，不长一看就懂）。
使用方法；
第一步：设置webConfig数据库映射（注意！一定要设置主键，R.user.userId其实就是主键的String名字，是怎么实现的请看http://blog.csdn.net/a7178077/article/details/41981557
）。
第二步：随意找个controller
使用方法：tableName是数据库表名的String[]，直接传入表名就可以，created(数据表名数组，所有Model存放的包名)。
生成效果
哦。。对了。。别忘记加入包。.
