Jsp文件
<body>
<%
String ipath = request.getRealPath("/Files");
File file = new File(ipath);
File[] files = file.listFiles();
for(int i=0;i<files.length;i++){
String fname = files[i].getName();
fname = java.net.URLEncoder.encode(fname,"utf-8");
out.println(files[i].getName());
out.println("<a href='Down.action?name="+fname+"'>"+files[i].getName()+"</a><br />");
}
%>
</body>
Struts.xml文件
<action name="Down" class="action.DownAction">
<result name="success" type="stream">
<param name="contentDisposition">attachment;filename="${filename}"</param>
<param name="inputName">downloadFile</param>
</result>
</action>
在下載時一直是Down.txt IE是down.action
看看你的struts.xml裡面，在result結果集裡面的，名字為contentdisposition參數標簽裡面的文件名是否用了ognl表達式來動態獲取文件名
