本文介绍了如何使用Java实现文件上传功能，包括图片和视频的上传，并详细解释了如何将上传的图片和视频分别显示在网页上。
PictuerAndVideo.jsp
<%@ page language="java" contentType="text/html; charset=GB18030"

PictuerAndVideoSuccess.jsp

pageEncoding="GB18030" import="cn.action.FileUploadAction;" %>
<%@ taglib uri="/struts-tags" prefix="s"%>

${message}

</html>
struts.xml:

namespace="/fileUpload">

</result>
<result name="input">/PictuerAndVideo.jsp</result>
</action>
</package>
web.xml:
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
但如果深入一点的话，要把上传的图片分别显示出来，又该怎么做呢？？
