用Struts上传多个文件的方法
时间:2011-04-02
最近在做Struts项目时遇到了上传多个文件的问题。在网上查了不少资料，也没有找到用Struts上传多个文件的例子。我经过几天的研究，实现了用Struts上传多个文件的功能。现在贴出来让大家共享！
一。建立ActionForm
package com.cnehu.struts.form;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionError;
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.upload.MultipartRequestHandler;
/**//**
*
* Title:UpLoadForm
*
*
* Copyright: Copyright (c) 2005 techyang ;http://blog.csdn.net/techyang
*
* @author techyang
* @version 1.0
*/
public class UpLoadForm extends ActionForm
...{
public static final String ERROR_PROPERTY_MAX_LENGTH_EXCEEDED ="org.apache.struts.webapp.upload.MaxLengthExceeded";
protected FormFile theFile;
protected FormFile theFile2;
public FormFile getTheFile()
...{
return theFile;
}
public void setTheFile(FormFile theFile)
...{
this.theFile = theFile;
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request)
...{
ActionErrors errors = null;
//has the maximum length been exceeded?
Boolean maxLengthExceeded = (Boolean) request
.getAttribute(MultipartRequestHandler.ATTRIBUTE_MAX_LENGTH_EXCEEDED);
if ((maxLengthExceeded != null) && (maxLengthExceeded.booleanValue()))
...{
errors = new ActionErrors();
errors.add(ERROR_PROPERTY_MAX_LENGTH_EXCEEDED, new ActionError(
"maxLengthExceeded"));
}
return errors;
}
/**//**
* @return Returns the theFile2.
*/
public FormFile getTheFile2()
...{
return theFile2;
}
/**//**
* @param theFile2 The theFile2 to set.
*/
public void setTheFile2(FormFile theFile2)
...{
this.theFile2 = theFile2;
}
}

二、建立ActionServlet
package 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")))
{
