JSP实现从数据库导出数据到Excel下载的方法

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。
