很强大的jsp手写分页插件 实现json 等一些ajax技术 联合查询 模糊查询 条件查询
这个插件里面分页功能很强大，调用者只需赋几个值就可以了。
下面是ticket.jsp 全代码：
分页 Action 代码：
action中 方法也可以这样写：
Map<String, String> requestParaMap = filterRequestParameter(request);
在dao里面 创建stringBuffer 对象 获得map中的值 看是否为空，不为空则 append 。为hql语句。可以看这个：http://yzz9i.iteye.com/admin/blogs/1141648
分页Dao 代码：
分页 一个接收查询结果的rest.jsp ：
