我的网站上线了,请大家提点建议

最近比较闲,学习了struts2,和ibatis,所以确定利用学习到的知识开发一个网站,看到百度知道,问问,比较火,结构也比较简单,就开发了一个问答类型的网站.

网站采用 spring + struts + ibatis 搜索采用compass DB mysql

网站测试地址:http://panxiuyan34.jspcn.net/ 正式域名:www.123why.com(怎么样比较好记吧)

昨天抓取了百度的30000条数据,没有违法吧!

希望大家给我提点建议,和改进的地方.

分享一个分页代码(基于标签jstl),希望对大家有用,类似淘宝,javaeye的形式有页块

在FireFox下看的时候，页面布局完全乱了~~

本人美工不好,只能在IE看,以后慢慢会兼容的!谢谢
