利用spring boot 怎么实现一个视频点播功能

public class InitVodCilent {

 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;
 }
}

@Override
 public void removeMoreAlyVideo(List videoIdList) {
 try {
  //初始化对象
  DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
  //创建删除视频request对象
  DeleteVideoRequest request = new DeleteVideoRequest();

  //videoIdList值转换成 1,2,3
  String videoIds = StringUtils.join(videoIdList.toArray(), ",");

  //向request设置视频id
  request.setVideoIds(videoIds);
  //调用初始化对象的方法实现删除
  client.getAcsResponse(request);
 }catch(Exception e) {
  e.printStackTrace();
  throw new EduException(20001,"删除视频失败");
 }
 }

 //根据视频id删除阿里云视频
 @DeleteMapping("removeAlyVideo/{id}")
 public R removeAlyVideo(@PathVariable String id) {
 try {
  //初始化对象
  DefaultAcsClient client = InitVodCilent.initVodClient(ConstantVodUtils.ACCESS_KEY_ID, ConstantVodUtils.ACCESS_KEY_SECRET);
  //创建删除视频request对象
  DeleteVideoRequest request = new DeleteVideoRequest();
  //向request设置视频id
  request.setVideoIds(id);
  //调用初始化对象的方法实现删除
  client.getAcsResponse(request);
  return "删除成功";
 }catch(Exception e) {
  e.printStackTrace();
 }
 }

 //删除多个阿里云视频的方法
 //参数多个视频id List videoIdList
 @DeleteMapping("delete-batch")
 public R deleteBatch(@RequestParam("videoIdList") List<String> videoIdList) {
 vodService.removeMoreAlyVideo(videoIdList);
 return "删除成功";
 }
