一、Java上传SDK

文档地址：https://help.aliyun.com/document_detail/53406.html?spm=a2c4g.11186623.6.1065.4068192b1bTgc5

SDK下载地址页面：https://help.aliyun.com/document_detail/51992.html?spm=a2c4g.11186623.2.25.34ea3815KgAGSf

1、安装SDK

jar包未开源，不能直接在maven中央仓库下载到，手动吧依赖安装到本地仓库中，使用maven命令进行安装。
解压下载好的压缩包，在lib目录下进入通过CMD进入命令行模式，输入命令：

mvn install:install-file 
-DgroupId=com.aliyun
-DartifactId=aliyun-sdk-vod-upload 
-Dversion=1.4.12
-Dpackaging=jar 
-Dfile=aliyun-java-vod-upload-1.4.12.jar

现在jar包安装好了。

2、配置properties文件

#阿里云 vod
#不同的服务器，地址不同
aliyun.vod.file.keyid=<您的AccessKeyId>
aliyun.vod.file.keysecret=<您的AccessKeySecret>

#为了可以上传正常大小文件 配置以下
# 最大上传单个文件大小：默认1M
spring.servlet.multipart.max-file-size=1024MB
# 最大置总上传的数据大小 ：默认10M
spring.servlet.multipart.max-request-size=1024MB

3、编写从配置文件中取值工具

@Component
public class ConstantPropertiesUtil implements InitializingBean {

    @Value("${aliyun.vod.file.keyid}")
    private String keyId;
    @Value("${aliyun.vod.file.keysecret}")
    private String keySecret;

    public static String KEY_ID;
    public static String KEY_SECRET;

    @Override
    public void afterPropertiesSet() throws Exception {
        KEY_ID = keyId;
        KEY_SECRET = keySecret;
    }
}

4、编写视频上传代码（流式上传）

完整示例代码在阿里云sdk的jar包中
https://help.aliyun.com/document_detail/53406.html?spm=a2c4g.11186623.4.2.394c7bdcZARxCA

@Service
public class VodServiceImpl implements VodService {
    @Override
    public String uploadVideoAly(MultipartFile file) {

        try{
            String accessKeyId = ConstantPropertiesUtil.KEY_ID;
            String accessKeySecret = ConstantPropertiesUtil.KEY_SECRET;
            //fileName: 上传文件的原始名
            String fileName = file.getOriginalFilename();
            //title: 上传后显示的名称
            /**
             * substring的作用:
             *   假如你要上传的文件名为小猪佩奇.mp4, 
             *   substring(0,fileName.lastIndexOf("."))
             *   可以帮助你把文件名截取为 小猪佩奇 
             *   
             *   该函数为：substring(int beginIndex,int endIndex)
             *   fileName.lastIndexOf(".")即为文件名中的最后一个.的下标
             */
            String title = fileName.substring(0,fileName.lastIndexOf("."));
            //上传文件的输入流
            InputStream inputStream = file.getInputStream();
            //创建上传请求
            UploadStreamRequest request = new UploadStreamRequest(accessKeyId, accessKeySecret, title, fileName, inputStream);
            //创建上传实例
            UploadVideoImpl uploader = new UploadVideoImpl();
            UploadStreamResponse response = uploader.uploadStream(request);
            //定义一个videoId
            String videoId = null;
            if (response.isSuccess()){
                videoId = response.getVideoId();
            }else {
                videoId = response.getVideoId();
            }
            return videoId;
        }catch (Exception e){
            e.printStackTrace();
            return null;
        }
    }
}

二、根据阿里云点播控制台的视频ID获取视频播放地址及视屏播放凭证

文档地址：https://help.aliyun.com/document_detail/57756.html?spm=a2c4g.11186623.6.906.11a83bd995vyLf

1、初始化对象

public class InitObject {
    public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException {
        String regionId = "cn-shanghai";  // 点播服务接入区域
        DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);
        DefaultAcsClient client = new DefaultAcsClient(profile);
        return client;
    }
}

2、根据视频ID获取视频播放地址

public static void getPlayUrl()throws Exception{
    //根据视频id获取视频播放地址
    //创建初始化对象
    DefaultAcsClient client = InitObject.initVodClient("<您的AccessKeyId>", "<您的AccessKeySecret>");
    //创建获取视频地址request和response
    GetPlayInfoRequest request = new GetPlayInfoRequest();
    GetPlayInfoResponse response = new GetPlayInfoResponse();
    //向request对象里面设置视频id
    request.setVideoId("<您的视频ID>","VideoId1","VideoId2"....);
    //调用初始化对象里面的方法，传递request，获取数据
    response = client.getAcsResponse(request);
    //如果有多个视频的话
    List<GetPlayInfoResponse.PlayInfo> playInfoList = response.getPlayInfoList();
    //播放地址
    for (GetPlayInfoResponse.PlayInfo playInfo : playInfoList) {
        System.out.print("PlayInfo.PlayURL = " + playInfo.getPlayURL() + "\n");
    }
    //Base信息
    System.out.print("VideoBase.Title = " + response.getVideoBase().getTitle() + "\n");
}

3、根据视频ID获取视频播放凭证

public static void getPlayAuth() throws Exception{
    //根据视频id获取视频播放凭证
    //创建初始化对象
    DefaultAcsClient client = InitObject.initVodClient("<您的AccessKeyId>", "<您的AccessKeySecret>");
    //创建获取视频凭证request和response
    GetVideoPlayAuthRequest request = new GetVideoPlayAuthRequest();
    GetVideoPlayAuthResponse response = new GetVideoPlayAuthResponse();
    //向request对象里面设置视频id
    request.setVideoId("<您的视频ID>");
    //调用初始化对象里面的方法，得到凭证
    response = client.getAcsResponse(request);
    System.out.println("playauth:"+response.getPlayAuth());
}
