之前我在博客中也写过一篇关于导出文件的博文，但感觉限制性很大。最近做一个项目感觉此方式的导出文件比较通用，可以参考借鉴，以下为代码：
1.导出页面代码MyJsp.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>导出</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">
<script src="scripts/jquery/jquery-1.7.1.js" charset="utf-8"></script>
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<div>
<input type="button" value="导出 " onclick="exportExcel();"/>
</div>
<form id="exportForm" action="exportExcel.jsp" method="post">
<input type="hidden" name="exportExcelsql" id="exportsql" value=""/>
<input type="hidden" name="ids" id="ids" value=""/>
</form>
</body>
<script type="text/javascript">
function exportExcel(){//导出文件
$('#exportForm').submit();
}
</script>
</html>
2.导出业务处理代码exportExcel.jsp
<%@ page language="java" import="java.util.*,java.io.OutputStream" pageEncoding="utf-8"%>

request.setCharacterEncoding("utf-8");
System.out.println("aaaaa///==================");
response.setContentType("octets/stream");
//response.addHeader("Content-Disposition", "attachment;filename=test.xls");
String excelName = "通讯录列表";//导出文件名称
//转码防止乱码
response.setContentType("application/vnd.ms-excel;charset=GBK");
response.addHeader("Content-Disposition", "attachment;filename="+new String(excelName.getBytes("gb2312"), "ISO8859-1" )+".xls");
String[] headers = new String[]{"部门","组","姓名","手机号码","邮箱","领域","技能","照片","身份证"};//表头信息列
try {
List<Map<String,Object>> list=new ArrayList<Map<String,Object>>();
//====模拟导出的数据
for(int i=0;i<3;i++){
Map map=new HashMap<String,Object>();

}
//==============
