当我使用vlc-plugin和Spring控制器播放视频时，控制器被调用两次，第二次出现错误：

这是我使用vlc-plugin的客户端嵌入元素：
<div id="videoPlayerContainer">
<embed type="application/x-vlc-plugin" pluginspage="http://www.videolan.org" src="subject/play?subjectId=X" width="500" height="300" />
</div>
这是我的控制器：
/**
* Gets stream to the broadcasting video of the subject.
*/
@RequestMapping(method = RequestMethod.GET, value = PLAY)
public void play(final UserEntity sessionUser, @RequestParam("subjectId") int subjectId, HttpServletResponse res) {
String path = null;
try {
SubjectEntity subject = subjectService.getById(subjectId);
path = storageService.getFilePathBySubject(subject, FileType.SD);
if(StringUtils.isBlank(path)) {
logger.warn("Missing path of the '" + FileType.SD + "' file corresponding with the subject '" + subjectId + "': " + path);
res.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
return;
}
File file = new File(path);
res.setHeader("Content-Disposition", "attachment; filename=" + file.getName().replace(" ", "_"));
res.setHeader("Content-Type", "video/mp4");
res.setHeader("Content-Length", String.valueOf(file.length()));
InputStream inputStream = new FileInputStream(file);
ServletOutputStream outputStream = res.getOutputStream();
IOUtils.copy(inputStream, outputStream);
res.flushBuffer();
res.setStatus(HttpStatus.OK.value());
IOUtils.closeQuietly(inputStream);
IOUtils.closeQuietly(outputStream);
// return new FileSystemResource(path);
} catch(Exception ex) {
// ...
}
}
在第二次调用时，该行会抛出异常：
IOUtils.copy(inputStream, outputStream);
这是唯一被调用两次的控制器。
我正在使用Spring 4.0.6.RELEASE。
无论如何都可以播放视频，但我不会对这种情况感到放心......
有人有想法吗？
感谢您的帮助。
