如何解决spring中的多部分解析器？？java.lang.NoClassDefFoundError:org/apache/commons/fileupload/FileItemFactory

pom.xml

因此，当我给出一张图片并点击submit时，我会遇到这样的错误

甚至我在pom.xml中添加了“commons logging” momcab-servlet.xml中的“multipartResolver”的“bean”甚至没有在我的tomcat中运行。所以我知道我的错误发生在哪里。在此方面的任何帮助都是感激的。

谢谢你，我解决了我的问题。我刚刚添加了

commons fileupload

，但我没有添加

commons io

，所以我添加了它们，我的问题就解决了

为什么要添加

公共日志

帮助？您缺少了

commons fileupload

dependency.@M.Deinum如果您滚动我发布的“pom.xml”文件，您可以看到我添加了一个依赖项“commons-logging-1.2.1”。这里的问题是，当我在pom.xml中添加“commons logging”依赖项并运行服务器时，我没有收到任何错误。但是，当我在dispatcher-servlet.xml中添加“bean”并运行服务器时，我得到的错误是您的堆栈跟踪正在抱怨

commons fileupload

中缺少类，而不是

commons logging

。另外，不是将堆栈跟踪作为图像发布，而是将它们作为代码发布，以便它们可读和可滚动（堆栈跟踪的有趣部分实际上丢失了）。您有一个1.2.2版的

commons fileupload

依赖项，该依赖项很古老（2010年），请至少使用较新的1.3.2版本。stacktrace应该是文本，而不是图片。我们相信您有一个例外，因此最好使用文本而不是图片。为什么添加
