JavaEE实验2报告-昆明理工大学

昆明理工大学信息工程与自动化学院学生实验报告（2012—2013学年第一学期）课程名称：JAVAEE技术开课实验室：信自楼4442012年11月19日年级、专业、班计科10级学号姓名成绩实验项目名称实验二Servlet程序设计指导教师杨云飞教师评语教师签名：年月日一、实验目的通过上机，熟练掌握servlet编程、过滤器、监听器的编程。二、内容及要求1、上机内容：编写index.jsp，里面包含注册、显示数据清单、写入图片、显示图片的连接。当用户选择注册时，首先进行客户端ip地址是否是黑名单的检测，如果不是则转到注册页面；在显示所有的数据清单的页面中增加一个链接，仿照例题编写输出为EXCEL的servlet，点击时链接时执行它。实现给数据表中的photo列写入图片，图片文件直接放在服务器上。实现按输入的编号显示对应的图片。实现登录，在登录界面中生成验证码（验证码不出现数字4）。登录成功则转到main.jsp，显示网站的在线用户人数、当前用户、点击率、在线用户列表。通过过滤器实现登录过滤检查，不允许用户直接请求main等其他页面；通过=过滤器给所有的页面底部加上“昆明理工大学计算机系”+班级+学号+姓名用监听器实现实现网站所有网页的访问次数累计，在线用户数统计、在现用户列表更新。三、步骤及具体实施1、简要描述程序的开发流程、文件部署截图、及各种配置；2、程序代码packagejavaee.filter;importjava.io.*;importjavax.servlet.*;importjavax.servlet.http.*;importjavax.servlet.FilterChain;importjavax.servlet.FilterConfig;importjavax.servlet.ServletException;importjavax.servlet.ServletRequest;importjavax.servlet.ServletResponse;publicclassFootFilterimplementsFilter{ privateStringfooter=null;
