你可以有特殊的过滤子类(取决于你想要检索的内容),并且每个子类都会实现它的createCountQuery()和createQuery().

然后,您可以将Filter放到Velocity上下文中,然后您可以从此类中检索所需的所有信息.

当您设置当前页面时,您将更新所需的所有其他信息(即currentStartPageNo,currentEndPageNo).

您还可以使用refresh()方法将过滤器恢复到其初始状态.

当然,当用户在Filter所属的搜索页面上导航时,您应该在会话中保留相同过滤器的实例(我的意思是您的Web框架,如Struts,turbine等).

这只是一个指导方针,一个想法,它不是完全编写的可执行代码,只是一个让你开始朝着一个方向前进的例子.

我还建议你一个名为jqGrid的jQuery插件,它具有分页支持(尽管你必须有一个支持检索数据)和更多很酷的东西.您可以使用它在网格中显示数据.我和Velocity一起使用它没问题.它有许多非常好用的功能,如过滤器工具栏,可编辑单元格,JSON数据传输,XML等.老实说,我不知道它是否具有您需要的分页(我只使用导航中显示的一个页面,而您无法点击页面只需使用下一个上一个按钮进行导航),但它可能支持那.
