网上找的代码不知道为啥都不能用，自己写一个简陋点的。

struts-config.xml：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">



<struts-config>   <data-sources />   <form-beans >     <form-bean name="ttForm" type="action.TtForm" />



</form-beans>



  <global-exceptions />   <global-forwards />   <action-mappings >     <action path="/tt" scope="request" name="ttForm" type="action.TtAction" />



  </action-mappings>



  <message-resources parameter="ApplicationResources" /> </struts-config>

ActionForm：

/*

 * Generated by MyEclipse Struts

 * Template path: templates/java/JavaClass.vtl

 */

package action;



import java.util.HashMap;

import java.util.Map;



import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionForm;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.upload.FormFile;

import org.apache.struts.validator.LazyValidatorForm;



/** 

 * MyEclipse Struts

 * Creation date: 06-21-2008

 * 

 * XDoclet definition:

 * @struts.form name="ttForm"

 */

public class TtForm extends ActionForm {

	/*

	 * Generated Methods

	 */



	private Map<String, FormFile> map = new HashMap<String, FormFile>();

	/** 

	 * Method validate

	 * @param mapping

	 * @param request

	 * @return ActionErrors

	 */

	public ActionErrors validate(ActionMapping mapping,

			HttpServletRequest request) {

		// TODO Auto-generated method stub

		return null;

	}

	

	public void setFile(String key,FormFile f) {

		if (f != null && f.getFileSize() > 0) {

			this.map.put(key, f);

		}

	}

	

	public FormFile getFile(String key) {

		return this.map.get(key);

	}



	/** 

	 * Method reset

	 * @param mapping

	 * @param request

	 */

	public void reset(ActionMapping mapping, HttpServletRequest request) {

		// TODO Auto-generated method stub

	}



	public Map<String, FormFile> getMap() {

		return map;

	}



	public void setMap(Map<String, FormFile> map) {

		this.map = map;

	}

}

Action：

	public ActionForward execute(ActionMapping mapping, ActionForm form,

			HttpServletRequest request, HttpServletResponse response) throws Exception {

		// TODO Auto-generated method stub

		TtForm f = (TtForm)form;

		response.setCharacterEncoding("utf-8");

		PrintWriter out = response.getWriter();

		

		Set<Map.Entry<String, FormFile>> s = f.getMap().entrySet();

		out.println("共上传："+s.size()+"个文件<br/>");

		for (Map.Entry<String, FormFile> mm : s) {

			FormFile ff = mm.getValue();

			out.println("FileName:"+ff.getFileName()+"<br/>");

			out.println("FileSize:"+ff.getFileSize()+"<br/>");

			

			out.println("=============<br/>");

		}

		return null;

	}
