请教一下我这段文件下载的代码是否有问题

[白白了白呀白]

我用浏览器测试能弹窗下载，但是用postman测试用send and down 我后台打印流已经写完，但是postman却一直卡住

@GetMapping(value = "/test1")
//    @ResponseBody
    public void test1(HttpServletResponse response) throws XmlPullParserException, NoSuchAlgorithmException, InvalidKeyException, IOException {
        try {
//            //本地
//            MinioClient minioClient = new MinioClient("http://localhost:9000", "Z3TFF3HKCMFZP5BRN62T",
//                    "GOIuA5leqkPEZDTi2+t2dpM3kc7XiYUoNWb+0E9r");
            //服务器
            MinioClient minioClient = new MinioClient("http://localhost:9000", "Z3TFF3HKCMFZP5BRN62T",
                    "GOIuA5leqkPEZDTi2+t2dpM3kc7XiYUoNWb+0E9r");
            // Check whether the object exists using statObject().
            // If the object is not found, statObject() throws an exception,
            // else it means that the object exists.
            // Execution is successful.
            minioClient.statObject("asiatrip", "asiaphotos.zip");

            // Get input stream to have content of 'my-objectname' from 'my-bucketname'
            // 配置文件下载
            response.setHeader("content-type", "application/octet-stream");
            response.setContentType("application/octet-stream");
            // 下载文件能正常显示中文
            response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("asiaphotos.zip", "UTF-8"));

            OutputStream outputStream = response.getOutputStream();
            InputStream stream = minioClient.getObject("asiatrip", "asiaphotos.zip");

            // Read the input stream and print to the console till EOF.
            byte[] buf = new byte[16384];
            int bytesRead;
            while ((bytesRead = stream.read(buf, 0, buf.length)) >= 0) {
                System.out.println(new String(buf, 0, bytesRead));
                outputStream.write(buf, 0, bytesRead);
            }
            response.flushBuffer();

            // Close the input stream.
            stream.close();
            outputStream.close();
        } catch (MinioException e) {
            System.out.println("Error occurred: " + e);
        }
    }

[十八道胡同]

我们就是这么干的，谷歌内可以弹出，postma没测试过

 //通过文件输入输出流下载word
        //设置向浏览器端传送的文件格式
        response.setCharacterEncoding("utf-8");
        response.setContentType("multipart/form-data");
        try {
            response.setHeader("Content-Disposition", "attachment;fileName=" + java.net.URLEncoder.encode(fileName, "UTF-8"));
            FileInputStream is = new FileInputStream(outFile);
            ServletOutputStream os = response.getOutputStream();
            byte[] b = new byte[4096];

            int length;
            while ((length = is.read(b)) > 0) {
                os.write(b, 0, length);
            }
            os.close();
            is.close();
            outFile.delete();

        } catch (Exception var7) {
            throw new SysException(var7);
        }
