之前,写过一个Download.jsp文件,可以解决下载文件乱码问题(诸如:DOC,XSL文件等等).
后来发现,遇到中文名的文件的时候,文件下载将会报错~~~~
今天,通过改写原Download.jsp文件已经彻底解决了这个问题~
现在,把一整套的文件上传下载的方法给贴出来~~~以便大家借鉴!~!~!~!~!

文件上传:
-----------------------------------------
准备工作:导入著名的SmartUpload.jar组件包
upload.jsp文件
---------------------------------------------------------
<%@ page contentType="text/html; charset=gb2312" %>
<%
request.setCharacterEncoding("gb2312"); // 这句话很重要，否则遇到中文就出错~
%>
上传
---------------------------------------------------------
upload_ok.jsp文件
---------------------------------------------------------
<%@ page contentType="text/html;charset=gb2312" %>
<%@ page import="com.jspsmart.upload.*" %>
上传成功!
<%
int count=0;
String fileName = null;
mySmartUpload.initialize(pageContext);
mySmartUpload.upload();
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(0);
if (!myFile.isMissing()) {
//String ext=myFile.getFileExt();//得到后缀
fileName = myFile.getFileName();
myFile.saveAs("/files/" + fileName);//你要存放文件所在文件夹的相对路径
out.println("文件:"+fileName+"上传成功!
文件大小:" + myFile.getSize() + "kb
");
}

---------------------------------------------------------
文件下载:
-----------------------------------------
文件的超连接写法范例:
<% String fname ="中文测试.xsl"; //假设你的文件名是:中文测试.xsl
%>
下 载
文件的超连接写法范例-2 重新用utf-8对文件名编码:
<%@ page contentType="text/html;charset=gb2312" session="true"%>
<% String name=java.net.URLEncoder.encode("世界文化.doc","UTF-8"));%> 世界文化.doc
