String filename =  "文件名";String userAgent = request.getHeader("User-Agent"); //针对IE或者以IE为内核的浏览器：if (userAgent.contains("MSIE")||userAgent.contains("Trident")) {    filename = java.net.URLEncoder.encode(filename, "UTF-8");} else {//非IE浏览器的处理：    filename = new String(filename.getBytes("UTF-8"),"ISO-8859-1");}
