Struts2中，我们在我们的应用程序，我的文件上传struts2的上传功能。现在，我的就是，我们需要让上传到的“docx”和“的。xlsx”。我列出的“应用程序/ msword”和“应用程序/ vnd.ms-excel的”为allowedTypes在strut.xml。通过这一点，我们可以只上传的“doc”和“XLS”文件，但不能的“docx”和“的。xlsx”的文件。
新增WPS、MS Office2010文件的MIME类型：
<!-- 支持MS Office2003-2010，WPS Office 的Word、Excel、PPT-->
<param name="fileUpload.allowedTypes">
application/vnd.ms-excel,application/msword,application/vnd.ms-powerpoint
,
application/vnd.openxmlformats-officedocument.wordprocessingml.document,
application/vnd.openxmlformats-officedocument.presentationml.presentation,
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,
application/kswps,
application/kset,
application/ksdps
</param>
