private videoService videoService;
@GetMapping("/addVideo")
public String getAddVideo(Model model)
{
model.addAttribute("videoToAdd", new Video ());
return "Video/videoUpload";
}
@PostMapping("/addVideo")
public String postAddVideo(@Valid @ModelAttribute("videoToAdd")Video video,
BindingResult result)
{
if(result.hasErrors())
{
return "Video/videoUpload";
}
this.videoService.addOrUpdateVideo(video);
return "redirect:/video/addVideo";
}
@GetMapping("/{id}")
public String getSingleVideo(@PathVariable Long id,Model model)
{
Optional<Video> videoOptional = this.videoService.findById(id);
if(videoOptional.isPresent())
{
model.addAttribute("videoToShow",videoOptional.get());
return "Video/getVideo";
}
return "redirect:/video/addVideo";
}

在设置视频源之前，我应该将字节转换成文件/多部分文件或类似的东西吗？
我应该建立一个像responseentity这样的方法吗？
我被这个问题困住了。我读过blob，但大多数教程都与.jpg或.pdf文件相关。我感谢所有的帮助和提示。
