如题:我在网上找了N天了,也找了几种方法,但我都没有试成功,不知道是什么问题.
我就是不知道怎么样在actionForm中定义这样的一个FormFile数组,并且怎么来set和get它.我现在用的一种方法是这样子的:
ActionForm:
private List spaths=new ArrayList(); public FormFile getSpath(String i) {
return (FormFile)spaths.get(Integer.parseInt(i));
} public void setSpath(String i,FormFile spath) {
this.spaths.add(spath);
} public List getSpaths() {
return spaths;
}JSP:
<input type="file" id="spath<%=i%>" name='spath(<%=(i-1)%>)' class="input_detail" >
其中的那个"i"是会自动增加的,用循环实现的.
这个方法只能上传一个文件,其它的就不行了.
哪位能帮帮我啊.有代码的话可发到
谢谢啦!

this.spaths.add(spath);
} 请问i是干什么的?
这个方法中好象没有用到这个参数
多余的...如果问题解决了,把原代码给我发一份,谢谢[email protected]
我也不清楚.如果解决了我会发给你的.
String attCount=StringHelper.convertStringNull(request.getParameter("attCount"));
int idAtt=0;
if(!attCount.equals(""))
idAtt=Integer.parseInt(attCount);
String rootPath = (String) ConfigInfoVO.configInfoProps.get("RootPath");
String filePath = (String) ConfigInfoVO.configInfoProps.get("InviBidAttUploadFolder");
//filePath += inviBiddingVO.getInvitebid_proname()+"/";
Hashtable files = form.getMultipartRequestHandler().getFileElements();
FormFile ff[] = null;
ff = new FormFile[files.size()];
Enumeration fileKey = files.keys();
int i = 0;
while (fileKey.hasMoreElements()) {
String ffname = (String) fileKey.nextElement();
ff[i] = (FormFile) files.get(ffname);
i++;
}
Set attSet = new HashSet();
for( i =0;i<ff.length;i++){
FormFile file = ff[i];
String planFileName=file.getFileName();
String planFileExtendName="";
if(planFileName!=null && !planFileName.equals(""))
planFileExtendName=planFileName.substring(planFileName.lastIndexOf("."));
InviBidAttVO inviBidAttVO = new InviBidAttVO();
inviBidAttVO.setInvitebid_attpath(filePath);
inviBidAttVO.setInvitebid_attname(planFileName);
inviBidAttVO.setInvitebid_attrename(MyUUIDHexGenerator.getInstance().generate()+planFileExtendName);
inviBidAttVO.setInviBiddingVO(inviBiddingVO);
attSet.add(inviBidAttVO);
//上载附件
try {
if(!planFileName.equals("") && !filePath.equals("") && !file.getFileName().equals(""))
FileUpload.upload(file, inviBidAttVO.getInvitebid_attrename(), rootPath+inviBidAttVO.getInvitebid_attpath());
}catch (IOException ex) {
throw new ServiceException("error.upload.files");
}
}
inviBiddingVO.setInviBidAttSet(attSet);
用list接值,在action用循环存储数据就可以了

{
public static final String ERROR_PROPERTY_MAX_LENGTH_EXCEEDED = "org.apache.struts.webapp.upload.MaxLengthExceeded"; protected FormFile theFile;

二。建立ActionServletpackage com.cnehu.struts.action;import java.io.*;
import javax.servlet.http.*;
import org.apache.struts.action.*;
import org.apache.struts.upload.FormFile;import com.cnehu.struts.form.UpLoadForm;/**
* <p>
* Title:UpLoadAction
* </p>
* <p>
* Copyright: Copyright (c) 2005 techyang http://blog.csdn.net/techyang
* </p>
* @author techyang
* @version 1.0
*/public class UpLoadAction extends Action
{
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception
{
String encoding = request.getCharacterEncoding();
if ((encoding != null) && (encoding.equalsIgnoreCase("utf-8")))
{
response.setContentType("text/html; charset=gb2312");//如果没有指定编码,编码格式为gb2312
}
UpLoadForm theForm = (UpLoadForm) form;
FormFile file = theForm.getTheFile();//取得上传的文件
FormFile file2=theForm.getTheFile2();
try
{
/*
* 取当前系统路径D:\Tomcat5\webapps\coka\ 其中coka 为当前context
*/
String filePath = this.getServlet().getServletContext()
.getRealPath("/");
InputStream stream = file.getInputStream();//把文件读入
ByteArrayOutputStream baos = new ByteArrayOutputStream();
/*
* 建立一个上传文件的输出流 如果是linux系统请把UploadFiles后的"\\"换成"/"
*/
OutputStream bos = new FileOutputStream(filePath +
"UploadFiles\\"+file.getFileName());
//D:\Tomcat5\webapps\coka\UploadFiles\DSC01508.JPG
/* System.out.println(filePath +
"UploadFiles\\"+file.getFileName());
System.out.println(filePath);*/
request.setAttribute("fileName",filePath + "/"
+ file.getFileName());
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1)
{
bos.write(buffer, 0, bytesRead);//将文件写入服务器
}
bos.close();
stream.close();
InputStream stream2 = file2.getInputStream();//把文件读入
ByteArrayOutputStream baos2 = new ByteArrayOutputStream();
OutputStream bos2 = new FileOutputStream(filePath +
"UploadFiles\\"+file2.getFileName());//建立一个上传文件的输出流
int bytesRead2 = 0;
byte[] buffer2 = new byte[8192];
int i=0;
while ((bytesRead2 = stream2.read(buffer2, 0, 8192)) != -1)
{
bos2.write(buffer2, 0, bytesRead2);//将文件写入服务器
}
bos2.close();
stream2.close();
} catch (Exception e)
{
System.err.print(e);
}
return mapping.findForward("display");
}
}
三。建立上传用的JSP文件 upload.jsp<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<html:html>
<head>
<title>用Struts上传文件</title>
</head>
<body>
<html:form action="/uploadsAction" enctype="multipart/form-data">
<html:file property="theFile"/>
<html:file property="theFile2"/><html:submit/>
</html:form>
</body>
</html:html>四。配置struts-config.xml文件<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<data-sources />
<form-beans >
<form-bean name="uploadsForm" type="com.cnehu.struts.form.UpLoadForm" />
</form-beans> <global-exceptions />
<global-forwards >
</global-forwards> <action-mappings >
<action name="uploadsForm" type="com.cnehu.struts.action.UpLoadAction" path="/uploadsAction">
<forward name="display" path="/display.jsp" />
</action>
</action-mappings>
</struts-config>
完,希望能帮上你
