JSP导出Excel奇怪的乱码有关问题

??? 今天需要做一个从页面导出Excel的功能。在测试的过程中发现了一个奇怪的乱码问题。当仅有一条数据的时候导出的Excel会出现乱码，但是当多余一条数据的时候就没有乱码，真是奇怪。
??? 但还是解决了（添加了代码中红色的那行），现在我只把JSP的代码贴出来。
?
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page contentType="application/msexcel" %>
<%?
??? //就是靠这一行，让前端浏览器以为接收到一个excel档??
??? response.setHeader("Content-disposition","attachment; filename=Excle.xls");????
%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
