自主设计通用JSP网站源代码提供
好久没来过论坛了,刚完成一个网站的后台制作,准备把代码开放,西北农林科技大学迎评专题网([url=http://pj.nwsuaf.edu.cn]http://pj.nwsuaf.edu.cn[/url]),该站点完全基于MVC封装,所有资料动态页统一程序生成静态页,单点登陆控制,统一的日志记录以及友好的错误处理,实现HTML代码过滤,登陆验证码设计及密码MD5加密并作非法字符效验,灵活的资料更新以及文件上传功能,能对上传图片自动生成一定规格缩略图和并提供集成的图象管理系统,除了利用了struts和log4j两个开源产品以外,所有代码自主设计,所有的类除servlet外都已经生成jdk文档,需要源程序和文档请在下面附自己的邮箱地址,我逐个邮寄,程序中有不足或则能够增加功能的地方,希望大家不吝赐教![ Last edited by aleel on 2004-12-1 at 03:45 ] 下面附上一部分类的源码,对各个方法均有符合jdk要求的注释,可以生成jdk文档便于阅读,由于该网站部署在Linux环境下,所以实际部署的类和现在公布的略有差别,但现在这些类在中文Windows系统上是完全可以执行的,这是由于在部署之前不知道系统将部署在Linux平台,所以采用的是GB2312编码才会出现这种问题,希望各位部署应用的时候最好能够能够UTF-8编码,这样将完全保证Java系统的跨平台性,而我的系统只能说是一个失败了,虽然通过打补丁的方法解决了这个问题
