本文介绍如何使用Java进行视频上传处理，同时返回视频的URL以及自动生成缩略图的URL，涵盖了文件上传、视频处理及图片生成的关键步骤。

@Component
public class OSSClientUtil {

    protected static final Logger log = LoggerFactory.getLogger(OSSClientUtil.class);

    private static String endpoint = "http://XXXXXXXXXX.com";

    //阿里云API的bucket名称
    private static String bucketName = "XXXXXX";

    //阿里云API的密钥Access Key ID
    private static String accessKeyId = "XXXXXXXXXX";

    //阿里云API的密钥Access Key Secret
    private static String accessKeySecret = "XXXXXXXXXXXXXXXXX";

    //OSSClient ossClient = new OSSClient(endpoint, accessKeyId,accessKeySecret);


    /**
     * 上传图片
     *
     * @param file
     * @return
     */
    public String uploadImg2Oss(MultipartFile file) {
        OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

//        OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
        if (file.getSize() > 1024 * 1024 * 2) {
            return "图片太大";//RestResultGenerator.createErrorResult(ResponseEnum.PHOTO_TOO_MAX);
        }
        String originalFilename = file.getOriginalFilename();
        String substring = originalFilename.substring(originalFilename.lastIndexOf(".")).toLowerCase();
        Random random = new Random();
        String name = random.nextInt(10000) + System.currentTimeMillis() + substring;
        try {
            InputStream inputStream = file.getInputStream();
            this.uploadFile2OSS(inputStream, name);
            ossClient.shutdown();
            return "MrZhang/"+name;//RestResultGenerator.createSuccessResult(name);
        } catch (Exception e) {
            return "上传失败";//RestResultGenerator.createErrorResult(ResponseEnum.PHOTO_UPLOAD);
        } finally {
            ossClient.shutdown();
        }
    }

    //上传视频
    public String uploadVideo(MultipartFile file) throws IOException {
        String originalFilename = file.getOriginalFilename();

        }
        String name = random.nextInt(10000)+ System.currentTimeMillis() + substring;
        try {
            InputStream stream=file.getInputStream();
