Tomcat上传文件限制大小：org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException

  SpringBoot项目，操作阿里云的视频点播测试上传视频，出现如下异常，主要原因是tomcat上传文件大小有限制的，默认1M大小。

  解决方案：设置上传文件大小限制，在application.properties配置上传文件大小即可！

#最大上传单个文件大小：默认1M,现在是1G
spring.servlet.multipart.max-file-size=1024MB
# 最大置总上传的数据大小 ：默认10M,现在是1G
spring.servlet.multipart.max-request-size=1024M
