本文實例講述了JSP實現從數據庫導出數據到Excel下載的方法。分享給大家供大家參考，具體如下：

關鍵代碼：

<%@ page contentType="application/msexcel" %><%  //response.setHeader("Content-disposition","inline; filename=videos.xls");  response.setHeader("Content-disposition","attachment; filename=test.xls");  //以上這行設定傳送到前端瀏覽器時的檔名為test.xls  //就是靠這一行，讓前端瀏覽器以為接收到一個excel檔 %>

簡單測試例子：

<%@ 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");   //以上這行設定傳送到前端瀏覽器時的檔名為test.xls   //就是靠這一行，讓前端瀏覽器以為接收到一個excel檔  %> <%@ 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>
