我正在尝试结合使用 Struts2 和 Spring 来上传文件。但是，不知怎的，在到达我的动作课、我的文件之后，filename和文件内容类型都出来了null。我尝试寻找问题所在，但没有结果。下面是我的文件上传的代码。
index.jsp:
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<s:head />
</head>
<s:actionerror />
<s:form action="uploadAction" method="POST" enctype="multipart/form-data">
<s:file name="fileUpload" label="Choose File" size="40" />
<s:submit value="Upload" name="submit" />
</s:form>
