之前,寫(xiě)過(guò)一個(gè)Download.jsp文件,可以解決下載文件亂碼問(wèn)題(諸如:DOC,XSL文件等等).
后來(lái)發(fā)現,遇到中文名的文件的時(shí)候,文件下載將會(huì )報錯~~~~
今天,通過(guò)改寫(xiě)原Download.jsp文件已經(jīng)徹底解決了這個(gè)問(wèn)題~
現在,把一整套的文件上傳下載的方法給貼出來(lái)~~~以便大家借鑒!~!~!~!~!

文件的超連接寫(xiě)法范例:
<% String fname ="中文測試.xsl"; //假設你的文件名是:中文測試.xsl
%>
<A target="_blank" href="Download.jsp?filename=<%=fname%>">下 載</A>
文件的超連接寫(xiě)法范例-2 重新用utf-8對文件名編碼:
<%@ page contentType="text/html;charset=gb2312" session="true"%>
<% String name=java.net.URLEncoder.encode("世界文化.doc","UTF-8"));%> <a href="c:\<%=name%>">世界文化.doc</a>
