    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, "+", " "); if (newFileName.length() > 150) { newFileName = new String(filename.getBytes("GB2312"), "ISO8859-1"); newFileName = StringUtils.replace(newFileName, " ", " "); } 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; } }
