怎么样通过JSP实现从数据库导出数据到Excel下载？
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。
