基于Struts1.2的动态多文件上传 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　首先是web xml配置

　　<?xml version= encoding= ISO ?> <!DOCTYPE web app PUBLIC //Sun Microsystems Inc //DTD Web Application //EN app_ _ dtd >

　　<servlet> <servlet name>action</servlet name> <servlet class> apache struts action ActionServlet</servlet class> <init param> <param name>config</param name> <param value>/WEB INF/struts config xml</param value> </init param> <load on startup> </load on startup> </servlet>

　　<servlet mapping> <servlet name>action</servlet name> <url pattern>* do</url pattern> </servlet mapping>

　　</web app>然后是struts config xml

　　<?xml version= encoding= UTF ?> <!DOCTYPE struts config PUBLIC //Apache Sofare Foundation//DTD Struts Configuration //EN config_ _ dtd >

　　</action mappings> <message resources parameter= hb struts ApplicationResources /> </struts config>

　　然后是页面test jsp 这段就是网上COPY的动态生成页面

　　<%@ page language= java pageEncoding= utf %>

　　<%@ taglib uri= bean prefix= bean %> <%@ taglib uri= prefix= %> <%@ taglib uri= logic prefix= logic %> <%@ taglib uri= tiles prefix= tiles %>

　　<!DOCTYPE HTML PUBLIC //W C//DTD HTML Transitional//EN > <:> <head> <title> multiUploadDemo </title>

　　<script language= javascript > var num = ;

　　function upload() document getElementById( status ) innerHTML = 文件上传中 ; multiUploadForm submit();

　　function additem(id) var row cell str;

　　row = eval( document all[ + +id+ + ] ) insertRow(); if(row != null ) cell = row insertCell(); str= <input type= + + file + + name=uploadFile[ + num + ] file><input type= + + button + + value= + + 删除 + + onclick= deleteitem(this + + tb + + ); > cell innerHTML=str; num++; function deleteitem(obj id) var rowNum curRow; curRow = obj parentNode parentNode; rowNum = eval( document all +id) rows length ; eval( document all[ + +id+ + ] ) deleteRow(curRow rowIndex); function callback(msg) document getElementById( status ) innerHTML = 文件上传完成 <br> + msg; </script> <body bgcolor= #ffffff > <div id= status ></div> <:form method= post action= /multiUpload do enctype= multipart/form data target= hidden_frame >

　　</:form> <iframe name= hidden_frame id= hidden_frame ></iframe> <input type= button name= btnAddFile value= Add File onclick= additem( tb ) /> <input type= button name= btnUpload value= upload onclick= upload() /> </body> </:>

　　下面是FORM和ACTION

我把下面个文件放在FORM包中

　　UploadFile java

　　package hb struts form; import java io Serializable;

　　import apache struts upload FormFile;

　　public class UploadFile implements Serializable private FormFile file; public FormFile getFile() System out println( run in uploadFile getFile() ); return file; public void setFile(FormFile file) this file = file;

　　MultiUploadForm java

　　package hb struts form; import java util ArrayList; import java util List;

　　import apache struts action ActionForm;

　　import hb struts UploadFile;

　　public class MultiUploadForm extends ActionForm private List myFiles;

　　public MultiUploadForm() myFiles = new ArrayList(); myFiles add(new UploadFile()); public List getMyFiles() return myFiles;

　　//注意这个方法的定义不加中间的循环是会出错的

　　public UploadFile getUploadFile(int index) int size = myFiles size(); if(index>size ) for(int i= ;i<index size+ ;i++) myFiles add(new UploadFile()); return (UploadFile)myFiles get(index); public void setMyFiles(List myFiles) this myFiles = myFiles;

　　最后是action

　　package hb struts action;

　　import java io IOException; import java io PrintWriter; import java util List;

　　import javax servlet HttpServletRequest; import javax servlet HttpServletResponse;

　　import apache struts action Action; import apache struts action ActionForm; import apache struts action ActionForward; import apache struts action ActionMapping; import apache struts upload FormFile;

　　public class MultiUploadAction extends Action public ActionForward execute(ActionMapping mapping ActionForm form HttpServletRequest request HttpServletResponse response) MultiUploadForm multiUploadForm = (MultiUploadForm) form;

　　List myFiles = multiUploadForm getMyFiles(); String fileStr = ; for (int i = ; i < myFiles size(); i++) UploadFile uploadFile = (UploadFile) myFiles get(i); FormFile file = uploadFile getFile();

　　if (file == null) System out println( file is null ); else

　　// 能运行到这里就可以使用单个文件上传的方法进行上传了循环而已 System out println( filename>>>>>>>>>> + file getFileName()); System out println( file size>>>>>>>>>> + file getFileSize()); fileStr += filename::: + file getFileName() + file size::: + file getFileSize();

　　 // 返回文本 try response setHeader( ContentType text/;charset=gbk ); PrintWriter out = response getWriter(); out write( <script>parent callback( upload file success + fileStr + )</script> ); catch (IOException e) e printStackTrace();

　　return null;
