 8             //title:上传之后现实的名称
 9             String title = fileName.substring(0,fileName.lastIndexOf("."));
10             //inputStream:上传文件输入流
11             InputStream inputStream = file.getInputStream();

20                 videoId = response.getVideoId();
21             } 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
22                 videoId = response.getVideoId();
23             }

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.
at org.apache.catalina.connector.Request.parseParts(Request.java:2912)

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
