        @RequestParam(value = "id", required = true) Long id,
        @RequestParam(value = "print", defaultValue = "false") Boolean print) throws Exception {

    response.setCharacterEncoding("UTF-8");
    response.setHeader("Content-Disposition", "attachment; filename*=UTF-8''" + fname);

如果您的意思是在达到终点时想要立即下载文件，那么以下代码可以为您提供帮助。

@RequestMapping(value = "/somePath", method = RequestMethod.GET)
@ResponseBody
public void getFileForPrint(HttpServletResponse response,
        @RequestParam(value = "id", required = true) Long id,
        @RequestParam(value = "print", defaultValue = "false") Boolean print) throws Exception {
        String filename="nameOfFileWhenDownloaded.txt";
        try {
            response.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE);
            response.setHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
            OutputStreamWriter osw = new OutputStreamWriter(response.getOutputStream());
            osw.write(contentsOfTheFile);
            osw.flush();
            osw.close();
            response.flushBuffer();
        } catch (Exception e) {
            e.printStackTrace();
            throw new Exception("Error is sending file");
        }
}
