spring boot 应用程序中的多部分文件上传不适用于 tomcat 版本 9.0.31。但是这个功能在旧版本 9.0.30 上工作正常。但是这个版本有一个漏洞，被迫升级版本。请参阅下面给出的错误

 "timestamp": "2020-03-09T08:01:56.169+0000",
"status": 500,
"error": "Internal Server Error",
"message": "Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.impl.IOFileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly",

错误日志如下

nested exception is org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.impl.IOFileUploadException: Processing of multipart/form-data request failed. Stream ended unexpectedly] with root causeorg.apache.tomcat.util.http.fileupload.MultipartStream$MalformedStreamException: Stream ended unexpectedly

请帮助解决这个问题。
