文件上传报错（tomcat）

pom里面不引入commons-fileupload（1.3.1版本），tomcat启动报错如下

java.lang.ClassNotFoundException: org.apache.commons.fileupload.FileUploadException

引入后，tomcat起不来

警告: Called stop() on failed component [org.apache.catalina.webresources.StandardRoot@5a079446] to trigger clean-up but it failed too

org.apache.catalina.LifecycleException: An invalid Lifecycle transition was attempted ([before_stop]) for component [org.apache.catalina.webresources.DirResourceSet@a319a2e] in state [INITIALIZED]
