很大一部分参照了网络上,可是不是十分完整,所以就整理了一个可以执行的出来,好久没有用Struts了.希望不要笑我.

这里的jar包就是那些了,具体的看下面的图片有jar包.程序这里附上,

说一点,这里最主要的还是一下这个地方.

List<String> uploadFileName;
List<File> upload;

关于Java文件

package com.upload; import java.io.File; import java.util.List; import javax.servlet.http.HttpServletRequest; import org.apache.commons.io.FileUtils; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; @SuppressWarnings("serial") public class UploadAction extends ActionSupport { List<String> uploadFileName; List<File> upload; public String upload() { try { // 得到路径, String filePath = getRequest().getSession().getServletContext() .getRealPath("/") + "UploadPath//"; if (upload == null) { return SUCCESS; } else { for (int i = 0; i < upload.size(); i++) { if (upload.get(i) != null) { String fName = uploadFileName.get(i); String osName = filePath + fName; File file = new File(osName); FileUtils.copyFile(upload.get(i), file); } } } } catch (Exception e) { e.printStackTrace(); } return SUCCESS; } // getter and setter protected HttpServletRequest getRequest() { return (HttpServletRequest) ActionContext.getContext().get( ServletActionContext.HTTP_REQUEST); } public List<String> getUploadFileName() { return uploadFileName; } public void setUploadFileName(List<String> uploadFileName) { this.uploadFileName = uploadFileName; } public List<File> getUpload() { return upload; } public void setUpload(List<File> upload) { this.upload = upload; } }

关于jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>多上传主页面</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page">  <mce:script type="text/javascript"></mce:script> </head> <body> <table height="20%" align="center"> <tr align="center"> <td colspan="2" height="100%" align="center"> <span>STRUTS多上传文件范例</span> </td> </tr> </table> <table height="60%" align="center"> <tr align="center"> <td align="center"> <table align="center"> <s:form method="post" theme="simple" name="upload" enctype="multipart/form-data" action="upload"> <tr> <td> 设备信息图片 </td> <td width="82%"> <table> <tr> <td width="30%"> <input type="button" onclick="addComponent();" value="添加文件" /> 最多只能添加10张 </td> </tr> <tr> <td> <span id="files"> <input size='30' type='file' name='upload' /> <p /> </span> </td> </tr> </table> </td> </tr> <tr> <td colspan="2"> <input type="submit" value="提交" > </td> </tr> </s:form> </table> </td> </tr> </table> <table height="20%" align="center"> <tr align="center"> <td height="100%" align="center"> 作者----LZG </td> </tr> </table> </body> </html>

关于web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <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> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
