springMVC下载中文文件名乱码【原】

  重点就在于添加  "attachment;filename*=utf-8'zh_cn'" + fileName

//遇到的现象是,下载含有中文文件名的文件时,能获取到文件,但是使用IE正常,使用firefox,chrome文件名却乱码.
//既然如此,就区分一下浏览器再返回好了,处理方式如下
//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){ 
      /**文件下载图片乱码处理**/
      String fileName = URLEncoder.encode(fileInfo.getcFReName(), "UTF-8");
      if (request.getHeader("User-Agent").toUpperCase().indexOf("MSIE") > 0) {//1.IE浏览器UTF-8 
        headers.setContentDispositionFormData("attachment", fileName); 
      }else{//2.其他浏览器attachment;filename*=utf-8'zh_cn 
        response.setHeader("Content-Disposition", "attachment;filename*=utf-8'zh_cn'" + fileName);//重点
      }
      fileByte = this.fileManager.fetchFile(fileInfo);
    }
    
    return new ResponseEntity<byte[]>(fileByte , headers, HttpStatus.OK);
  }
