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 stubreturn 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 stubTtForm 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;}
