File zip = ZipUtil.zip(folderPath);
try (InputStream fileBufferInStream = new BufferedInputStream(new FileInputStream(zip));
     OutputStream netOutStream = new BufferedOutputStream(response.getOutputStream());) {
    // 将zip读入到内存的buffer
    byte[] buffer = new byte[fileBufferInStream.available()];
    int read = fileBufferInStream.read(buffer);
    if (read == -1) {
        // 读入失败
        throw new ServiceException("生成失败");
    }
    // 写入网络流
    response.setContentType("application/octet-stream");
    response.setCharacterEncoding(Charsets.UTF_8.name());
    String fileName = URLEncoder.encode("视频监控信息", Charsets.UTF_8.name());
