# 一 创建视频点播微服务 #

## 1 创建模块 ##

Artifact：service\_vod

## 2 配置pom.xml ##

<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>
    </dependencies>

## 3 安装非开源jar包 ##

参考文档：[https://help.aliyun.com/document\_detail/53406.html?spm=a2c4g.11186623.6.980.5f027853fqcnnZ\#h2-2-sdk-2][https_help.aliyun.com_document_detail_53406.html_spm_a2c4g.11186623.6.980.5f027853fqcnnZ_h2-2-sdk-2]

在本地Maven仓库中安装jar包：

下载视频上传SDK，解压，命令行进入lib目录，执行以下代码

mvn install:install-file -DgroupId=com.aliyun -DartifactId=aliyun-sdk-vod-upload -Dversion=1.4.11 -Dpackaging=jar -Dfile=aliyun-java-vod-upload-1.4.11.jar

## 4 配置application.yml ##

server:
      port: 8130 # 服务端口
    
    spring:
      profiles:
        active: dev # 环境设置
      application:
        name: service-vod # 服务名
      cloud:
        nacos:
          discovery:
            server-addr: localhost:8848 # nacos服务地址
      servlet:
        multipart:
          max-file-size: 1024MB # 最大上传单个文件大小：默认1M
          max-request-size: 1024MB # 最大置总上传的数据大小 ：默认10M
    
    aliyun:
      vod:
        keyid: XXXXXXXXXX
        keysecret: XXXXXXXXXX
        templateGroupId: XXXXXXXXXX#转码模板组id
        workflowId: XXXXXXXXXX#工作流id

## 5 logback-spring.xml ##

修改日志路径为vod

## 6 创建启动类 ##

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) // 取消数据源自动配置
    @ComponentScan({"com.atguigu.guli"})
    @EnableDiscoveryClient
    public class ServiceVodApplication {
        public static void main(String[] args) {
            SpringApplication.run(ServiceVodApplication.class, args);
        }
    }

## 7 启动项目 ##

# 二 实现视频上传 #

## 1 文件上传参考 ##

[https://help.aliyun.com/document\_detail/53406.html?spm=a2c4g.11186623.6.980.5f027853fqcnnZ\#h2-3-3][https_help.aliyun.com_document_detail_53406.html_spm_a2c4g.11186623.6.980.5f027853fqcnnZ_h2-3-3]

## 2 从配置文件读取常量 ##

创建常量读取工具类：VodProperties.java

@Data
    @Component
    @ConfigurationProperties(prefix = "aliyun.vod")
    public class VodProperties {
        private String keyid;
        private String keysecret;
        private String templateGroupId;
        private String workflowId;
    }

## 3 视频上传业务 ##

接口

public interface VideoService {
        /**
         * 功能描述：视频上传
         *
         * @author cakin
         * @date 2020/12/13
         * @param inputStream 视频输入流
         * @param originalFilename 视频文件名
         * @return String 视频id
         */
        String uploadVideo(InputStream inputStream, String originalFilename);
    }

实现

/**
         * 功能描述：视频上传
         *
         * @param inputStream      视频输入流
         * @param originalFilename 视频文件名
         * @return String 视频id
         * @author cakin
         * @date 2020/12/13
         */
        @Override
        public String uploadVideo(InputStream inputStream, String originalFilename) {
            // 视频的标题
            String title = originalFilename.substring(0, originalFilename.lastIndexOf("."));
            // 视频上传请求
            UploadStreamRequest request = new UploadStreamRequest(
                    vodProperties.getKeyid(),
                    vodProperties.getKeysecret(),
                    title, originalFilename, inputStream);
            /* 模板组ID(可选) */
    //        request.setTemplateGroupId(vodProperties.getTemplateGroupId());
            /* 工作流ID(可选) */
    //        request.setWorkflowId(vodProperties.getWorkflowId());
            // 删除视频实现
            UploadVideoImpl uploader = new UploadVideoImpl();
            // 上传结果
            UploadStreamResponse response = uploader.uploadStream(request);
            // 视频id
            String videoId = response.getVideoId();
            if (StringUtils.isEmpty(videoId)) {
                log.error("阿里云上传失败：" + response.getCode() + "-" + response.getMessage());
                throw new GuliException(ResultCodeEnum.VIDEO_UPLOAD_ALIYUN_ERROR);
            }
            return videoId;
        }

## 4 控制器 ##

/**
    * 功能描述：上传视频
    *
    * @param file 文件
    * @return R 返回给前端的数据
    * @author cakin
    * @date 2020/12/13
    */
    @PostMapping("upload")
    public R uploadVideo(@ApiParam(value = "文件", required = true) @RequestParam("file") MultipartFile file) {
        try {
            // 视频流
            InputStream inputStream = file.getInputStream();
            // 文件名
            String originalFilename = file.getOriginalFilename();
            // 上传视频
            String videoId = videoService.uploadVideo(inputStream, originalFilename);
            return R.ok().message("视频上传成功").data("videoId", videoId);
        } catch (IOException e) {
            log.error(ExceptionUtils.getMessage(e));
            throw new GuliException(ResultCodeEnum.VIDEO_UPLOAD_TOMCAT_ERROR);
        }
    }

# 三 使用工作流 #

## 1 配置工作流 ##

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZW5ncWl1bWluZw_size_16_color_FFFFFF_t_70 2][]

## 2 设置请求参数 ##

将工作流id设置到request参数中

/* 工作流ID(可选) */
    request.setWorkflowId(vodProperties.getWorkflowId());

# 四 测试 #
