大家好,又见面了,我是你们的朋友全栈君。

=============================

(一)引入依赖

代码语言:javascript复制
<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>

        <artifactId>service</artifactId>

        <groupId>com.atguigu</groupId>

        <version>0.0.1-SNAPSHOT</version>

    </parent>

    <modelVersion>4.0.0</modelVersion>



    <artifactId>service_vod</artifactId>

    <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.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>

    </dependencies>

</project>

这里需要注意的是 aliyun-java-sdk-vod 飘红问题,aliyun-java-sdk-vod 没有开源,所以不能直接在pom文件中直接引用依赖。

通常情况下:

1、下载aliyun-sdk-vod-upload.jar

2、将测试样例解压,进入lib目录下,在命令行执行下面的命令

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

在pom文件中引入该依赖即可

代码语言:javascript复制
<dependency>

    <groupId>com.aliyun</groupId>

    <artifactId>aliyun-sdk-vod-upload</artifactId>

    <version>1.4.12</version>

 </dependency>

但有的时候确实不好使,小编就是这样

我的解决办法(直接导入jar包!!!):

(二)Spring Boot 后端部分


1、配置文件application.properties

代码语言:javascript复制
# 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=LTAI4GJ2dfYZAmAusqM4qwti

aliyun.vod.file.keysecret=JwctWzF9sxACGAX7FjZ5wd8ewvjCPl



# 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

2、controller

代码语言:javascript复制
package com.atguigu.vod.controller;



import com.aliyuncs.DefaultAcsClient;

import com.aliyuncs.vod.model.v20170321.DeleteVideoRequest;

import com.atguigu.commonutils.R;

import com.atguigu.commonutils.exceptionhandler.GuliException;

import com.atguigu.vod.Utils.ConstantVodUtils;

import com.atguigu.vod.Utils.InitVodCilent;

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("/eduvod/video")

@CrossOrigin

public class VodController {



    @Autowired

    private VodService vodService;



    //上传视频到阿里云

    @PostMapping("uploadAlyiVideo")

    public R uploadAlyiVideo(MultipartFile file) {

        //返回上传视频id

        String videoId = vodService.uploadVideoAly(file);

        return R.Ok().data("videoId",videoId);

    }



    //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 R.Ok();

        }catch(Exception e) {

            e.printStackTrace();

            throw new GuliException(20001,"删除视频失败");

        }

    }



    //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 R.Ok();

    }

} 

3、service

代码语言:javascript复制
package com.atguigu.vod.service;



import org.springframework.web.multipart.MultipartFile;



import java.util.List;



public interface VodService {

    //上传视频到阿里云

    String uploadVideoAly(MultipartFile file);



    void removeMoreAlyVideo(List<String> videoIdList);

}

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.vod.model.v20170321.DeleteVideoRequest;

import com.atguigu.commonutils.R;

import com.atguigu.commonutils.exceptionhandler.GuliException;

import com.atguigu.vod.Utils.ConstantVodUtils;

import com.atguigu.vod.Utils.InitVodCilent;

import com.atguigu.vod.service.VodService;

import org.apache.commons.lang3.StringUtils;

import org.springframework.stereotype.Service;

import org.springframework.web.multipart.MultipartFile;

import java.io.InputStream;

import java.util.ArrayList;

import java.util.List;

@Service

public class VodServiceImpl implements VodService {

代码语言:javascript复制
@Override

public String uploadVideoAly(MultipartFile file) {

    try {

        //accessKeyId, accessKeySecret

        //fileName:上传文件原始名称

        // 01.03.09.mp4

        String fileName = file.getOriginalFilename();

        //title:上传之后显示名称

        String title = fileName.substring(0, fileName.lastIndexOf("."));

        //inputStream:上传文件输入流

        InputStream inputStream = file.getInputStream();

        UploadStreamRequest request = new UploadStreamRequest(ConstantVodUtils.ACCESS_KEY_ID,ConstantVodUtils.ACCESS_KEY_SECRET, title, fileName, inputStream);



        UploadVideoImpl uploader = new UploadVideoImpl();

        UploadStreamResponse response = uploader.uploadStream(request);



        String videoId = null;

        if (response.isSuccess()) {

            videoId = response.getVideoId();

        } else { //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

            videoId = response.getVideoId();

        }

        return videoId;

    }catch(Exception e) {

        e.printStackTrace();

        return null;

    }

}



@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 GuliException(20001,"删除视频失败");

    }

}

}

### 4、utils

package com.atguigu.vod.Utils;

import com.aliyun.oss.ClientException;

import com.aliyuncs.DefaultAcsClient;

import com.aliyuncs.profile.DefaultProfile;

public class InitVodCilent {

代码语言:javascript复制
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;

}

}

代码语言:javascript复制
package com.atguigu.vod.Utils;



import org.springframework.beans.factory.InitializingBean;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.stereotype.Component;



@Component

public class ConstantVodUtils implements InitializingBean {



    @Value("${aliyun.vod.file.keyid}")

    private String keyid;



    @Value("${aliyun.vod.file.keysecret}")

    private String keysecret;



    public static String ACCESS_KEY_SECRET;

    public static String ACCESS_KEY_ID;



    @Override

    public void afterPropertiesSet() throws Exception {

        ACCESS_KEY_ID = keyid;

        ACCESS_KEY_SECRET = keysecret;

    }

}
