Spring MVC之ResposeEntity下载文件

Spring Mvc中用ResponseEntity方式下载文件如下:

@RequestMapping("/download")public ResponseEntity<byte[]> download(HttpServletRequest request,@RequestParam("fileName") String fileName) throws IOException {        String path = request.getServletContext().getRealPath("/uploadImages/");        File dwFile = new File(path+File.separator+fileName);        HttpHeaders headers = new HttpHeaders();        //下载显示的中文名,解决中文名称乱码问题        String downloadFileName = new String(fileName.getBytes("UTF-8"),"ISO-8859-1");        //application/octet-stream:二进制流数据        headers.setContentDispositionFormData("attachment",downloadFileName);        headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);        return new ResponseEntity<byte[]>(FileUtils.readFileToByteArray(dwFile),headers, HttpStatus.CREATED);    }}
