Convert MultipartFile file to File, get video duration

  public static File MultipartFileToFile(MultipartFile multiFile) {
        // 获取文件名
        String fileName = multiFile.getOriginalFilename();
        // 获取文件后缀
        String prefix = fileName.substring(fileName.lastIndexOf("."));
        // 若需要防止生成的临时文件重复,可以在文件名后添加随机码
 
        try {
            File file = File.createTempFile(fileName, prefix);
            multiFile.transferTo(file);
            return file;
        } catch (Exception e) {
            e.printStackTrace();

Get the video duration after converting to file:

	        // 将MultipartFile file转换成为File
	        File f_file = MultipartFileToFile(file);
	        String path = f_file.getCanonicalPath();
	        long duration_new = VideoUtil.getDuration(path);
	        duration = (int)duration_new;  // 获取的视频时长
	        f_file.delete();
