与上传单个文件类似，需要把File文件变为File数组

一、新建包cn.xs.fileupload,并建立FileUploadAction.java文件，内容如下：

// ---------------------------------------------------------// @author    sheng.xu// @version   1.0.0// @date2014年6月8日// ---------------------------------------------------------package cn.xs.fileupload;import java.io.File;import java.io.IOException;import org.apache.commons.io.FileUtils;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionContext;/** * @author sheng.xu * */public class FileUploadAction {private File[] image;//获取文件private String[] imageFileName;//获取文件名称private String[] imageContentType;//获取文件类型/** * @return the image */public File[] getImage() {return image;}/** * @param image the image to set */public void setImage(File[] image) {this.image = image;}/** * @return the imageFileName */public String[] getImageFileName() {return imageFileName;}/** * @param imageFileName the imageFileName to set */public void setImageFileName(String[] imageFileName) {this.imageFileName = imageFileName;}/** * @return the imageContentType */public String[] getImageContentType() {return imageContentType;}/** * @param imageContentType the imageContentType to set */public void setImageContentType(String[] imageContentType) {this.imageContentType = imageContentType;}public String execute() throws IOException {String realpath = ServletActionContext.getServletContext().getRealPath("/images");//获取文件上传后的存放目录的绝对路径System.out.println(realpath);if(image != null){File savedir = new File(realpath);if(!savedir.exists()){savedir.mkdirs();}for(int i = 0; i < image.length; i++){File savefile = new File(savedir,imageFileName[i]);FileUtils.copyFile(image[i], savefile);}ActionContext.getContext().put("message", "上传成功");}return "success";}public String requestFile(){return "success";}}

二、建立对应的jsp文件：fileupload.jsp内容如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body> <form action="${pageContext.request.contextPath}/test3/fileupload_execute.action" enctype="multipart/form-data" method="post">    <span style="white-space:pre"></span>文件1:<input type="file" name="image"><br>    <span style="white-space:pre"></span>文件2:<input type="file" name="image"><br>    <span style="white-space:pre"></span>文件3:<input type="file" name="image"><br>    <span style="white-space:pre"></span><input type="submit" value="上传"/>    </form>    {$message}</body></html>

三、建立struts.xml中配置action如下：

<action name="fileupload_*" class="cn.xs.fileupload.FileUploadAction" method = "{1}"><!-- 配置返回结果 --><result name="success">/WEB-INF/page/fileupload.jsp</result><result name="error">/error.jsp</result></action>

四、访问http://localhost:8080/Struts2/test3/fileupload_requestFile.action

注：上传文件大小的限制，可以在struts.xml文件中加入如下配置：<constant name="struts.mutipart.maxSize" value="10701096">
