环境搭建
-
一般情况下，项目会单独创建一个vod视频服务，来对视频进行相关操作。
-
配置aliyun基础环境，获取AccessKey和AccessKey Secret。（详见《Spring Cloud集成阿里云OSS完成头像上传功能》）
-
下载并安装jar包
如果要实现上传视频，则需要
aliyun-java-vod-upload-1.4.5.jar。因为
aliyun-java-vod-upload-1.4.5.jar还未正式开源，所以需要单独下载并安装到Maven本地仓库。在下载完jar包的文件目录下打开命令行输入：
mvn install:install-file -DgroupId=com.aliyun -DartifactId=aliyun-sdk-vod-upload -Dversion=1.4.5 -Dpackaging=jar -Dfile=aliyun-java-vod-upload-1.4.5.jar注意：
如果命令运行不了，说明Maven没有下载或者Maven没有配置环境变量，使用：mvn -v 测试命令行是否能够执行Maven命令。
-
pom.xml中引入相关依赖<dependencies> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-core</artifactId> <version>4.5.1</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-java-sdk-vod</artifactId> <version>2.15.11</version> </dependency> <dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>3.1.0</version> </dependency> <dependency> <groupId>com.aliyun</groupId> <artifactId>aliyun-sdk-vod-upload</artifactId> <version>1.4.5</version> </dependency> <dependency> <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20170516</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.69</version> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.2</version> </dependency> </dependencies> <!-- 阿里云Vod服务jar包的仓库 --> <repositories> <repository> <id>sonatype-nexus-staging</id> <name>Sonatype Nexus Staging</name> <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> -
配置
application.ymlspring: ... # 文件上传配置 servlet: multipart: # 单个视频文件限制1GB以内 max-file-size: 1024MB max-request-size: 1024MB # 阿里云Vod aliyun: vod: file: keyid: xxxxxxxxxxxxxx keysecret: xxxxxxxxxxxxxxxxxxxxxxx -
创建常量类
@Component public class ConstantPropertiesUtils implements InitializingBean { @Value("${aliyun.vod.file.keyid}") private String keyId; @Value("${aliyun.vod.file.keysecret}") private String keySecret; public static String ACCESS_KEY_ID; public static String ACCESS_KEY_SECRET; // 当读取application.yml时,自动给两个常量赋值 @Override public void afterPropertiesSet() throws Exception { ACCESS_KEY_ID = keyId; ACCESS_KEY_SECRET = keySecret; } }注意：该类变量读取的配置信息，默认是从
application.yml或者配置中心（Nacos，Spring Cloud Config）已经设置的配置文件中读取，如果不是上述配置文件，在类上配置注解指定配置文件即可。@PropertySource("classpath:xxx.yml") -
创建阿里云SDK工具类
@Component public class AliyunVodSDKUtils { // 初始化Vod客户端调用对象 public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) throws ClientException { // 点播服务接入区域 String regionId = "cn-shanghai"; DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret); DefaultAcsClient client = new DefaultAcsClient(profile); // SDK的调用依赖client对象 return client; } public static DefaultAcsClient initVodClient() throws ClientException { return initVodClient(ConstantPropertiesUtils.ACCESS_KEY_ID, ConstantPropertiesUtils.ACCESS_KEY_SECRET); } /** * 获取播放地址 * @param videoId 视频ID * @return GetPlayInfoResponse 获取视频播放响应数据 * @throws Exception */ public static GetPlayInfoResponse getPlayInfo(String videoId) throws Exception { // 创建发送请求客户端 DefaultAcsClient client = initVodClient(); GetPlayInfoRequest request = new GetPlayInfoRequest(); request.setVideoId(videoId); return client.getAcsResponse(request); } /** * 获取视频信息 * @param videoId 视频ID * @return GetVideoInfoResponse 获取视频信息响应数据 * @throws Exception */ public static GetVideoInfoResponse getVideoInfo(String videoId) throws Exception { // 创建发送请求客户端 DefaultAcsClient client = initVodClient(); GetVideoInfoRequest request = new GetVideoInfoRequest(); request.setVideoId(videoId); return client.getAcsResponse(request); } /** * 获取媒资信息 * @param pageNo 当前页号 * @param pageSize 每页容量 * @return SearchMediaResponse 查询媒资信息响应数据 * @throws ClientException */ public static SearchMediaResponse searchMedia(int pageNo, int pageSize) throws ClientException { // 创建发送请求客户端 DefaultAcsClient client = initVodClient(); SearchMediaRequest request = new SearchMediaRequest(); request.setFields("Title,CoverURL,Status"); request.setPageNo(pageNo); request.setPageSize(pageSize); request.setSearchType("video"); request.setSortBy("CreationTime:Desc"); return client.getAcsResponse(request); } /** * 删除视频 * @param videoIds 支持传入多个视频ID，多个用逗号分隔 * @return DeleteVideoResponse 删除视频响应数据 * @throws Exception */ public static DeleteVideoResponse deleteVideo(String videoIds) throws Exception { // 创建发送请求客户端 DefaultAcsClient client = initVodClient(); DeleteVideoRequest request = new DeleteVideoRequest(); request.setVideoIds(videoIds); return client.getAcsResponse(request); } }常用方法封装（Service层）
1. 上传视频
public String uploadVideo(MultipartFile video) { String videoId = null; try { String fileName = video.getOriginalFilename(); String title = fileName.substring(0, fileName.lastIndexOf('.')); InputStream inputStream = video.getInputStream(); // 创建请求对象 UploadStreamRequest request = new UploadStreamRequest( ConstantPropertiesUtils.ACCESS_KEY_ID, ConstantPropertiesUtils.ACCESS_KEY_SECRET, title, fileName, inputStream); // 创建文件上传器 UploadVideoImpl uploader = new UploadVideoImpl(); // 执行文件上传 UploadStreamResponse response = uploader.uploadStream(request); videoId = response.getVideoId(); } catch (IOException e) { throw new VideoUploadException(ResponseEnum.VIDEO_UPLOAD_ERROR); } // 如果上传成功，返回该视频的videoId return videoId; }2. 删除视频
public boolean deleteVideo(String videoId) { try { AliyunVodSDKUtils.deleteVideo(videoId); } catch (Exception e) { throw new VideoDeleteException(ResponseEnum.VIDEO_DELETE_ERROR); } return true; }3. 获取视频播放地址
public String getVideoPlayUrl(String videoId) { String playUrl = null; try { GetPlayInfoResponse response = AliyunVodSDKUtils.getPlayInfo(videoId); List<GetPlayInfoResponse.PlayInfo> playInfoList = response.getPlayInfoList(); // 获取播放地址 for (GetPlayInfoResponse.PlayInfo playInfo : playInfoList) { playUrl = playInfo.getPlayURL(); } } catch (Exception e) { e.printStackTrace(); } return playUrl; }4. 获取视频封面地址
public String getVideoCoverUrl(String videoId) { String coverUrl = null; try { DefaultAcsClient client = AliyunVodSDKUtils.initVodClient(); GetVideoInfoResponse response = AliyunVodSDKUtils.getVideoInfo(client, videoId); // 获取封面地址 coverUrl = response.getVideo().getCoverURL(); } catch (Exception e) { e.printStackTrace(); } return coverUrl; }5. 分页获取视频列表
public Map<String, Object> videoList(int pageNo, int pageSize) { Map<String, Object> videoMap = new HashMap<>(); List<VideoVo> videoList = new ArrayList<>(); try { SearchMediaResponse response = AliyunVodSDKUtils.searchMedia(pageNo, pageSize); if (response.getMediaList() != null && response.getMediaList().size() > 0) { videoMap.put("total", response.getTotal()); for (SearchMediaResponse.Media media : response.getMediaList()) { // 封装视频响应对象 VideoVo videoVo = new VideoVo(); // 获取aliyun上的视频信息 String videoId = media.getVideo().getVideoId(); videoVo.setCoverUrl(media.getVideo().getCoverURL()); videoVo.setPlayUrl(getVideoPlayUrl(videoId)); // 获取本地数据库中的视频信息 Video video = findVideoByVideoId(videoId); videoVo.setId(video.getId()); videoVo.setTitle(video.getTitle()); videoVo.setUploader(video.getUploader()); videoVo.setLikeCount(video.getLikeCount()); videoVo.setCollectCount(video.getCollectCount()); videoVo.setPlayCount(video.getPlayCount()); videoVo.setGmtCreate(video.getGmtCreate()); videoList.add(videoVo); } videoMap.put("videoList", videoList); } } catch (ClientException e) { e.printStackTrace(); } return videoMap; }
