上次文件代码报错，java.lang.ClassNotFoundException: org.apache.commons.fileupload.FileItemFactory

2018-09-11 11:11:08.235 ERROR 14352 --- [nio-8080-exec-5] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/fileupload/disk/DiskFileItemFactory] with root cause

 

java.lang.ClassNotFoundException: org.apache.commons.fileupload.disk.DiskFileItemFactory

 

或者：

2018-09-11 11:09:03.714 ERROR 14352 --- [nio-8080-exec-6] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileItem] with root cause

 

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

 

 

 

解决：

此类错误为maven依赖中少包，为什么没有编译报错这个问题尚待找出

maven中贴上这个可以解决：

<dependency>

<groupId>commons-fileuploadgroupId>

<artifactId>commons-fileuploadartifactId>

<version>1.3version>

dependency>
