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">

  <!-- 
  <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>
