以下测试了chrome firefox ie都ok

1.文件名最好不要带空格(有时firefox有问题文件后缀丢失, 还有就是linux系统空格有可能有问题)

2.源码

fileName = "诗圣杜!_-(&$试试ss甫 你好.xls"; fileName =  encodeFilename(fileName, request);  //注意此时后缀.xls也要包含进去response.setHeader("Content-Disposition", "attachment;filename=\""+fileName +"\"");public static String encodeFilename(String filename, HttpServletRequest request) {       /**         * 获取客户端浏览器和操作系统信息         * 在IE浏览器中得到的是：User-Agent=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; Alexa Toolbar)         * 在Firefox中得到的是：User-Agent=Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.7.10) Gecko/20050717 Firefox/1.0.6         */           String agent = request.getHeader("USER-AGENT");           try {           if ((agent != null) && (-1 != agent.indexOf("MSIE"))) {           String newFileName = URLEncoder.encode(filename, "UTF-8");           newFileName = StringUtils.replace(newFileName, "+", "%20");           if (newFileName.length() > 150) {              newFileName = new String(filename.getBytes("GB2312"), "ISO8859-1");              newFileName = StringUtils.replace(newFileName, " ", "%20");           }           return newFileName;           }          if ((agent != null) && (-1 != agent.indexOf("Mozilla"))) {          return new String(filename.getBytes("UTF-8"), "ISO8859-1");          //下载javax.mail-api-1.4.7.jar包          // return MimeUtility.encodeText(filename, "UTF-8", "B");          }      return filename;          } catch (Exception ex) {             return filename;          }      }
