一，先新建一个excel文件，调整格式（就是你所想要显示的格式），
二，把刚才新建的excel文件令存为.html（demo.html）文件，
三，新建一个jsp页面， 在该JSP页面头部设置response的ContentType为Excel格式
<% response.setContentType("application/vnd.ms-excel;charset=GBK"); %>
然后设置网页资料是以excel报表以线上浏览方式呈现或者是下载的方式呈现
<%
/ /这行设定传送到前端浏览器时的档名为test1.xls 就是靠这一行，让前端浏览器以为接收到一个excel档
//将网页资料以excel报表以线上浏览方式呈现
response.setHeader("Content-disposition","inline; filename=test1.xls");
//将网页资料以下载的方式
response.setHeader("Content-disposition","attachment; filename=test2.xls");
%>
然后把 demo.html的源代码粘贴在jsp页面，如下
<%@ page contentType="text/html; charset=GBK" %>
<% response.setContentType("application/vnd.ms-excel;charset=GBK");
response.setHeader("Content-disposition","attachment; filename=test2.xls");
%>
<!--以下为保持成html页面的excel的内容 demo.html页面-->

中文问题：
查看源代码时发现JSP文件中写死的中文为乱码，则在JSP文件头部添加一行
<%@ page contentType="text/html; charset=gb2312" %>
查看源代码时发现文字为中文，但是用Excel打开为乱码则在<html>与<head>中加入
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
在jsp页面中，要在excel中显示的内容可以从数据库中读取，在此就不做详细的介绍了
