本文实例讲述了JSP实现从数据库导出数据到Excel下载的方法。分享给大家供大家参考，具体如下：
关键代码：
<%@ page contentType="application/msexcel" %> <% //response.setHeader("Content-disposition","inline; filename=videos.xls"); response.setHeader("Content-disposition","attachment; filename=test.xls"); //以上这行设定传送到前端浏览器时的档名为test.xls //就是靠这一行，让前端浏览器以为接收到一个excel档 %>
简单测试例子：
<%@ page language="java" import="java.util.*,java.io.*" pageEncoding="GBK"%> <%@ page contentType="application/msexcel" %> <% //response.setHeader("Content-disposition","inline; filename=videos.xls"); response.setHeader("Content-disposition","attachment; filename=test.xls"); //以上这行设定传送到前端浏览器时的档名为test.xls //就是靠这一行，让前端浏览器以为接收到一个excel档 %> <%@ page import="org.springframework.web.context.WebApplicationContext"%> <%@ page import="com.test.*"%> <%@ page import="org.springframework.web.context.support.WebApplicationContextUtils"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <% WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(this.getServletContext()); UserManager um = (UserManager) ctx.getBean("userManager"); %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>spring jdbc test</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <br> <table border="1" width="100%"> <tr> <td>id</td> <td>name</td> </tr> <% List<User> users2=um.getUserList(); for(int i=0;i<users2.size();i++) { int t_id2=users2.get(i).getId(); String t_name2=users2.get(i).getName(); %> <tr> <td><%=t_id2 %></td> <td><%=t_name2 %></td> </tr> <% } %> </table> </body> </html>
希望本文所述对大家JSP程序设计有所帮助。
