本文介绍了一种基于Java的分页显示实现方法，通过自定义算法类RefactorPage实现了页面导航链接的动态生成，适用于不同数量的总页数场景。

这几天一直在看je的分页显示觉得做的非常不错.很合理人性化.于是乎自己也想搞个.网上找了找.貌似je用的是displaytag组件实现的..自己实在是懒.没去看.从网上找了段代码,然后修修补补改成如下格式

不过没有je做的好.有些地方没多想.请大家完善(这里的css是借用je的..robbin老大多包涵)

然后发算法类

算法一点都不简洁.请大家帮忙完善,谢谢了
上例子程序

我就不传包了.太慢,一共需要4个包

dbcp的三个.一个数据库连接.一个spring核心包,大家自己添加好了..spring的是2.5.6的
