参考How to solve this java.lang.NoClassDefFoundError: org/apache/commons/io/output/DeferredFileOutputStream?

And indeed, Commons FileUpload has Commons IO as a dependency. You need to download and drop commons-io.jar in the /WEB-INF/lib as well.

Commons FileUpload有依赖项Commons IO，请检查一下你是否包含了这个包，如果没有，上面的回答中有下载链接，你可以下载，然后放到相应的目录里面。或者检查一下配置文件里面有没有设置好这个依赖项。
