springboot整合视频点播

//上传视频到阿里云
    @Override
    public String uploadAyl(MultipartFile file) {
        try {
            //accessKeyId,accessKeySecret
            //fileName:上传文件原始名称
            String fileName = file.getOriginalFilename();
            //title:上传之后现实的名称
            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;
        }

    }

报错：

Caused by: java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field file exceeds its maximum permitted size of 1048576 bytes.

是因为上传视频超过规定的大小（上传大小问题）

解决方法：在application.properties里面进行文件大小设置

#最大上传单个文件大小;默认1MB
spring.servlet.multipart.max-file-size=1024MB
#最大置总上传数据大小:默认10MB
spring.servlet.multipart.max-request-size=1024MB

若前端页面上传没有效果并报错413请求体过大

 

 

，检查nginx的配置文件，nginx有上传大小限制

解决：打开nginx主要配置文件nginx.config,找到http{}添加client_max_body_size 1024m
