1、前端页面upload.jsp，后台处理程序UplodAction.java
2、struts.config的配置参数如下（没有设置ActionForm）：
<action input="/upload.jsp" path="/save" scope="request" type="yhp.test.web.UploadAction" validate="false">
<forward name="success" path="/list.do" />
</action>
3、upload.jsp页面中主要部分代码
<%@ page contentType="text/html; charset=GBK"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<html:html>
<head>
<title> 测试Struts利用SmartUpload上传文件 </title>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
</head>
<body>
<html:form action="/save.do" styleId="formItem" method="post" enctype="multipart/form-data">
<html:hidden property="id"/>
<html:file property="serverpath" styleClass="input-text"></html:file>
</html:form>
</body>
</html:html>
4、UploadAction.java
import com.jspsmart.upload.File;
import com.jspsmart.upload.Files;
import com.jspsmart.upload.SmartUpload;
public ActionForward doBatchsave(ActionMapping actionMapping,
ActionForm actionForm, HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse) throws Exception {
SmartUpload mySmartUpload = new SmartUpload();
mySmartUpload.initialize(getServlet().getServletConfig(),httpServletRequest, httpServletResponse);
mySmartUpload.upload();
//获取除文件以外的相关信息，例如upload.jsp中隐藏控件id的值
String strId=(String)mySmartUpload.getRequest().getParameter("id");
Files files=mySmartUpload.getFiles();
Collection col=files.getCollection();
Iterator it=col.iterator();
while(it.hasNext()){
File file=(File)it.next();
String oldFileName=file.getFileName();
String extname=file.getFileExt();
String fileName=Sequence.getSequence()+"."+extname;//产生一个唯一的文件名
file.saveAs("c:\\temp\"+fileName);
}
return (actionMapping.findForward("success"));
