struts 下载中文名文件

  <action name="fileDownload" class="DownloadAction" method="download">  <result name="success" type="stream">  <param name="contentType">text/plain</param>  <param name="contentDisposition">attachment;fileName="${fileName}"</param>  <param name="inputName">downloadFile</param>  <param name="buferSize">10240</param>  </result>  </action>

对文件名的处理

fileName = new String((URLEncoder.encode(<span style="font-family: Arial, Helvetica, sans-serif;">fileName </span><span style="font-family: Arial, Helvetica, sans-serif;">, "UTF-8")).getBytes("UTF-8"), "GBK");</span>

有点麻烦，但也总算解决了
