springMVC下載中文文件名亂碼【轉】

//遇到的現象是,下載含有中文文件名的文件時,能獲取到文件,但是使用IE正常,使用firefox,chrome文件名卻亂碼.
//既然如此,就區分一下瀏覽器再返回好了,處理方式如下

//RESTfull
@RequestMapping(path = { "/down/{fileId}" }, method = { RequestMethod.GET })
  public ResponseEntity<byte[]> handlerDownload(@PathVariable String fileId,HttpServletRequest request, HttpServletResponse response) throws IOException {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);
    FileInfo fileInfo = this.fileManager.fileInfoHandler(fileId);
    byte[] fileByte = null;
    if(fileInfo !=null){
      /**文件下載圖片亂碼處理**/
      String fileName = URLEncoder.encode(fileInfo.getcFReName(), "UTF-8");
      if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") > 0) {//1.IE瀏覽器UTF-8
        headers.setContentDispositionFormData("attachment", fileName);
      }else{//2.其他瀏覽器attachment;filename*=utf-8'zh_cn
        response.setHeader("Content-Disposition", "attachment;filename*=utf-8'zh_cn'" + fileName);//重點
      }
      fileByte = this.fileManager.fetchFile(fileInfo);
    }
    
    return new ResponseEntity<byte[]>(fileByte , headers, HttpStatus.OK);
  }
