Question

我试图从控制器传递视频字节，然后在jsp上读取和播放。它适用于大小小于1 MB MB的视频，但不适用于大于1 MB的文件。请帮我.. 这是我的控制器，它读取文件并将字节写入输出流。

@RequestMapping(value = "/playVideo", method = RequestMethod.GET)
@ResponseBody
public void  home(Locale locale, Model model,HttpServletRequest    request,HttpServletResponse response) throws IOException {
    logger.info("Welcome home! The client locale is {}.", locale);

    String filePath = "D://Uploads//s.mp4";        
    int fileSize = (int) new File(filePath).length();
    response.setContentLength(fileSize);
    response.setContentType("video");
    FileInputStream inputStream = new FileInputStream(filePath);
    ServletOutputStream outputStream = response.getOutputStream();
    int value = IOUtils.copy(inputStream, outputStream);
    System.out.println("File Size :: "+fileSize);
    System.out.println("Copied Bytes :: "+value);
    IOUtils.closeQuietly(inputStream);
    IOUtils.closeQuietly(outputStream);
    response.setStatus(HttpServletResponse.SC_OK);
}

这是我的jsp页面

您是否尝试使用更大的BufferSize？

response.setBufferSize(fileSize);

无法在Spring mvc中流式传输视频
