    @RequestMapping(value = "/downloadTemplate", method = RequestMethod.GET)
    public void downloadTemplate(HttpServletResponse response, HttpServletRequest request) {
        try {
            InputStream resourceAsStream = this.getClass().getClassLoader().getResourceAsStream("template/ggsjxqmb.zip");
            //获取要下载的模板名称
            String fileName = "广告设计需求模板.zip";
            response.setHeader("content-type", "application/octet-stream");
            response.setContentType("application/octet-stream");
            String encodeName = URLEncoder.encode(fileName, StandardCharsets.ISO_8859_1.toString());
            response.addHeader("Cache-Control", "no-cache, no-store, must-revalidate");
            response.addHeader("charset", "ISO_8859_1");
            response.addHeader("Pragma", "no-cache");
            response.setHeader("Content-Disposition", "attachment; filename=\"" + encodeName + "\"; filename*=ISO_8859_1''" + encodeName);

            OutputStream out = response.getOutputStream();
            byte[] b = new byte[2048];
            int len;
            while ((len = resourceAsStream.read(b)) != -1) {
                out.write(b, 0, len);
            }
            out.close();
            resourceAsStream.close();
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
