用java语言实现阿里云点播视频的视频名称、视频描述、视频分类、视频标签、视频时长、视频大小、存储地址、创建时间、修改时间

阿里云点播提供了Java SDK，可以方便地实现对视频的操作。以下是用Java语言实现阿里云点播视频信息的示例代码：

// 导入阿里云点播SDK
import com.aliyun.vod.upload.impl.UploadVideoImpl;
import com.aliyun.vod.upload.req.UploadVideoRequest;
import com.aliyun.vod.upload.resp.UploadVideoResponse;

public class VideoInfo {
    // 阿里云点播AccessKeyId
    private static final String accessKeyId = "your_access_key_id";
    // 阿里云点播AccessKeySecret
    private static final String accessKeySecret = "your_access_key_secret";
    // 阿里云点播API接入点
    private static final String endpoint = "http://vod.cn-shanghai.aliyuncs.com";
    // 阿里云点播上传文件的存储空间
    private static final String bucketName = "your_bucket_name";
    // 阿里云点播上传视频文件的路径
    private static final String objectName = "your_object_name";
    // 阿里云点播上传视频文件的本地路径
    private static final String filePath = "your_local_file_path";
    
    public static void main(String[] args) {
        // 创建上传视频请求对象
        UploadVideoRequest request = new UploadVideoRequest(accessKeyId, accessKeySecret, "test", filePath);
        request.setPartSize(2 * 1024 * 1024L);
        request.setTaskNum(1);
        // 设置视频信息
        request.setTitle("video_title");
        request.setDescription("video_description");
        request.setCateId(1L);
        request.setTags("video_tag1,video_tag2");
        // 上传视频文件
        UploadVideoImpl uploader = new UploadVideoImpl();
        UploadVideoResponse response = uploader.uploadVideo(request);
        // 获取视频信息
        String videoId = response.getVideoId();
        String videoName = response.getVideoName();
        String videoUrl = response.getVideoUrl();
        Long duration = response.getDuration();
        Long size = response.getSize();
        String createTime = response.getCreationTime();
        String modifyTime = response.getModificationTime();
        String storageLocation = response.getStorageLocation();
        // 输出视频信息
        System.out.println("Video ID: " + videoId);
        System.out.println("Video Name: " + videoName);
        System.out.println("Video URL: " + videoUrl);
        System.out.println("Duration: " + duration);
        System.out.println("Size: " + size);
        System.out.println("Create Time: " + createTime);
        System.out.println("Modify Time: " + modifyTime);
        System.out.println("Storage Location: " + storageLocation);
    }
}

注意：上述代码中的 `your_access_key_id`、`your_access_key_secret`、`your_bucket_name`、`your_object_name`、`your_local_file_path`、`video_title`、`video_description`、`video_tag1`、`video_tag2` 都需要替换成实际的值。此外，阿里云点播提供了丰富的API接口，可以更细粒度地控制视频的操作。
