JSP从数据库导出数据到Excel下载的实现

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:

[java] view plaincopy

<%@ 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");  

 %>
