[Java知识库]SpringBoot集成阿里云视频点播服务

前言

该文章会先简单的介绍一下阿里云的视频点播功能，然后演示如何在SpringBoot项目中集成视频点播，每一步都有记录，保证初学者也能看懂。

注：该文章主要记录SpringBoot集成阿里云视频点播代码，关于如何开通视频点播可以百度哦，不难的。

1、阿里云视频点播是什么

视频点播是集音视频采集、编辑、上传、自动化转码处理、媒体资源管理、分发加速、视频播放于一体的一站式音视频点播解决方案。

2、SpringBoot集成视频点播

1、创建一个SpringBoot项目
2、引入依赖

<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>
    </dependency>
    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
    </dependency>

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

	<!--swagger-->
	<dependency>
	    <groupId>io.springfox</groupId>
	    <artifactId>springfox-swagger2</artifactId>
	    <version>2.7.0</version>
	</dependency>
	
	<!--swagger ui-->
	<dependency>
	    <groupId>io.springfox</groupId>
	    <artifactId>springfox-swagger-ui</artifactId>
	    <version>2.7.0</version>
	</dependency>
</dependencies>

提示：其中有一个阿里云依赖暂时还未全部开源，在maven仓库中是下载不了的，可以直接下载阿里云提供的jar包：jar包路劲

3、配置application.properties文件

# 服务端口
server.port=8003
# 服务名
spring.application.name=service-vod

#阿里云 这里的keyid和keysecret是创建阿里云视频点播服务的时候得到的
aliyun.vod.file.keyid=your accessKeyId
aliyun.vod.file.keysecret=your accessKeySecret

# 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

4、创建常量类

package com.atguigu.vod.utils;

import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

/**
 * @author Eric
 * @create 2022-05-10 20:45
 */
@Component
public class ConstantPropertiesUtil implements InitializingBean {

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

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

    //定义两个公共访问常量
    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;
    }
}

5、创建工具类

package com.atguigu.vod.utils;

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.profile.DefaultProfile;

/**
 * @author Eric
 * @create 2022-05-09 20:25
 */
public class AliyunVodSDKUtils {
    public static DefaultAcsClient initVodClient(String accessKeyId, String accessKeySecret) {
        String regionId = "cn-shanghai";  // 点播服务接入区域（这个不能改，因为目前阿里云只有上海）
        DefaultProfile profile = DefaultProfile.getProfile(regionId, accessKeyId, accessKeySecret);
        DefaultAcsClient client = new DefaultAcsClient(profile);
        return client;
    }
}

6、创建service
service接口

package com.atguigu.vod.service;

import org.springframework.web.multipart.MultipartFile;

import java.util.List;

/**
 * @author Eric
 * @create 2022-05-10 20:49
 */
public interface VodService {
    //上传视频到阿里云
    String uploadAlyVideo(MultipartFile file);
}

serviceImpl实现类

package com.atguigu.vod.service.impl;

import com.aliyun.vod.upload.impl.UploadVideoImpl;
import com.aliyun.vod.upload.req.UploadStreamRequest;
import com.aliyun.vod.upload.resp.UploadStreamResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.vod.model.v20170321.DeleteVideoRequest;
import com.atguigu.servicebase.execptionhandler.GuliException;
import com.atguigu.utils.R;
import com.atguigu.vod.service.VodService;
import com.atguigu.vod.utils.AliyunVodSDKUtils;
import com.atguigu.vod.utils.ConstantPropertiesUtil;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;

/**
 * @author Eric
 * @create 2022-05-10 20:49
 */
@Service
@Slf4j
public class VodServiceImpl implements VodService {
    @Override
    public String uploadAlyVideo(MultipartFile file) {
        try {
            //获取文件的输入流
            InputStream inputStream = file.getInputStream();
            //文件原名称
            String originalFilename = file.getOriginalFilename();
            //文件上传后名称
            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 = response.getVideoId();
            if (!response.isSuccess()) {
                String errorMessage = "阿里云上传错误：" + "code：" + response.getCode() + ", message：" + response.getMessage();
                log.warn(errorMessage);
                if(StringUtils.isEmpty(videoId)){
                    throw new GuliException(20001, errorMessage);
                }
            }

            return videoId;
        } catch (IOException e) {
            throw new GuliException(20001, "guli vod 服务上传失败");
        }
    }
}

7、创建controller

package com.atguigu.vod.controller;

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.vod.model.v20170321.DeleteVideoRequest;
import com.atguigu.servicebase.execptionhandler.GuliException;
import com.atguigu.utils.R;
import com.atguigu.vod.service.VodService;
import com.atguigu.vod.utils.AliyunVodSDKUtils;
import com.atguigu.vod.utils.ConstantPropertiesUtil;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

import java.util.List;

/**
 * 上传视频到阿里云
 *
 * @author Eric
 * @create 2022-05-10 20:52
 */
@Api(tags = "上传视频到阿里云")
@RestController
@RequestMapping("/eduvod/video")
@CrossOrigin    //解决跨域
public class VodController {

    @Autowired
    private VodService vodService;

    @ApiOperation(value = "上传视频到阿里云")
    @PostMapping("uploadAlyVideo")
    public R uploadAlyVideo(@ApiParam(name = "file", value = "文件", required = true)
                                @RequestParam("file") MultipartFile file){

        String videoId = vodService.uploadAlyVideo(file);
        return R.ok().data("videoId",videoId).message("视频上传成功");
    }
}

8、启动服务，使用swagger测试即可，

总结

所有的步骤都可以根据阿里云SDK文档查看，官方文档写的很详细。
