一、整合阿里云vod实现视频上传

可参考阿里云官方SDK文档操作

1. 引入pom依赖

<dependencies>
    <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>aliyun-java-sdk-core</artifactId>
    </dependency>

    <dependency>
        <groupId>com.aliyun.oss</groupId>
        <artifactId>aliyun-sdk-oss</artifactId>
    </dependency>

    <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>aliyun-java-sdk-vod</artifactId>
    </dependency>

    <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>aliyun-sdk-vod-upload</artifactId>
    </dependency>

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
    </dependency>
    
  <dependency>
        <groupId>org.json</groupId>
        <artifactId>json</artifactId>5
    </dependency>
    
    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
    </dependency>

    <dependency>
        <groupId>joda-time</groupId>
        <artifactId>joda-time</artifactId>
    </dependency>
</dependencies>

2. application.properties

# 服务端口
server.port=8003
# 服务名
spring.application.name=service-vod
# 环境设置：dev、test、prod
spring.profiles.active=dev

#阿里云 vod
#不同的服务器，地址不同
aliyun.vod.file.keyid=XXXXX
aliyun.vod.file.keysecret=XXXX

#开启nacos服务
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

# 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. 启动类

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient
@ComponentScan(basePackages={"com.atguigu"})
public class VodApplication {
    public static void main(String[] args) {
        SpringApplication.run(VodApplication.class, args);
    }
}

4、创建常量类

ConstantPropertiesUtil.java
从配置文件中获取配置

@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 ACCESS_KEY_ID;
    public static String ACCESS_KEY_SECRET;
    @Override
    public void afterPropertiesSet() throws Exception {
        ACCESS_KEY_ID=keyId;
        ACCESS_KEY_SECRET=keySecret;
    }
}

4、创建视频点播的初始化类(多处使用)

//初始化
public class AliyunVodSDKUtils {
    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;
    }
}

5、创建service

接口：VideoService.java

public interface VodService {

    String uploadVod(MultipartFile file);

    void deleteALYVod(String id); //删除单个视频

    void deleteALLVod(List<String> ids); //删除多个视频
}

6、service实现类

@Service
public class VodServiceImpl implements VodService {
    @Override
    public String uploadVod(MultipartFile file){
        try {
            InputStream inputStream = file.getInputStream();
            String originalFilename = file.getOriginalFilename();
            String title = originalFilename.substring(0, originalFilename.lastIndexOf("."));
            UploadStreamRequest request = new UploadStreamRequest(
                    ConstantPropertiesUtil.ACCESS_KEY_ID,
                    ConstantPropertiesUtil.ACCESS_KEY_SECRET,
                    title, originalFilename, inputStream);
            UploadVideoImpl uploader = new UploadVideoImpl();
            UploadStreamResponse response = uploader.uploadStream(request);
            //如果设置回调URL无效，不影响视频上传，可以返回VideoId同时会返回错误码。
            // 其他情况上传失败时，VideoId为空，此时需要根据返回错误码分析具体错误原因
            String videoId = "";
            if (response.isSuccess()) {
                videoId=response.getVideoId();
            }else{
                videoId=response.getVideoId();
            }
            return videoId;
        } catch (Exception e) {
            throw new GuliException(20001, "阿里云上传失败");
        }
    }

    //阿里云删除视频
    @Override
    public void deleteALYVod(String id) {
        try{
            DefaultAcsClient client = AliyunVodSDKUtils.initVodClient(ConstantPropertiesUtil.ACCESS_KEY_ID, ConstantPropertiesUtil.ACCESS_KEY_SECRET);
            DeleteVideoRequest request = new DeleteVideoRequest();
            request.setVideoIds(id);
            client.getAcsResponse(request);
        }catch (Exception e){
            e.printStackTrace();
            throw new GuliException(20001, "视频删除失败");
        }
    }

    //阿里云批量删除视频
    @Override
    public void deleteALLVod(List<String> ids) {
        try{
            DefaultAcsClient client = AliyunVodSDKUtils.initVodClient(ConstantPropertiesUtil.ACCESS_KEY_ID, ConstantPropertiesUtil.ACCESS_KEY_SECRET);
            DeleteVideoRequest request = new DeleteVideoRequest();
            String join = StringUtils.join(ids, ",");
            request.setVideoIds(join);
            client.getAcsResponse(request);
        }catch (Exception e){
            e.printStackTrace();
            throw new GuliException(20001, "视频删除失败");
        }
    }
}

7、创建controller

package com.atguigu.vod.controller;

import com.aliyun.oss.model.MultipartUpload;
import com.atguigu.commonutils.R;
import com.atguigu.vod.service.VodService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

import java.util.List;

@RestController
@RequestMapping("/vod/video")
@CrossOrigin
public class VodController {

    @Autowired
    VodService vodService;
    //上传视频
    @PostMapping("aliyunVod")
    public R  aliyunVodUpload(MultipartFile file){
        String videoId=vodService.uploadVod(file);
        System.out.println(videoId);
        return R.ok().data("videoId",videoId);
    }

    //删除视频
    @DeleteMapping("{id}")
    public R  deleteVod(@PathVariable String id){
        vodService.deleteALYVod(id);
        return R.ok();
    }

    //批量删除所有视频
    @DeleteMapping("delAllVod/{ids}")
    public R  deleteVodAll(@RequestParam List<String> ids){
        vodService.deleteALLVod(ids);
        return R.ok();
    }
}
