smartupload 问题

wanghao1987 2009-04-26 08:20:17
这是抛出的异常：java.lang.IllegalArgumentException: Files' name is invalid or does not exist (1205).

下面是页面代码：

<%@ page language="java" contentType="text/html; charset=gbk"
pageEncoding="gbk"%>
<!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=gbk">
<title>传送文件</title>
</head>
<body>
<form action="upload" method="post" enctype="multipart/form-data">
<input type="file" id="Input_file"><br>
<input type="submit" value="上传" />
</form>
</body>
</html>


下面是后台代码：

package com.wanghao.upload;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.jspsmart.upload.*;
public class Upload extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response){
try {
SmartUpload su = new SmartUpload();
su.initialize(this.getServletConfig(), request, response);
su.upload();
com.jspsmart.upload.File f=su.getFiles().getFile(0);//异常在这一行抛出
String fname = f.getFileName(); // 文件名
f.saveAs("/updfile/"+fname, f.SAVEAS_VIRTUAL);
} catch (ServletException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (SmartUploadException e) {
e.printStackTrace();
}
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) {
doGet(request,response);
}

}
jar包已正常导入，web.xml也配置正确！不知道错误出在哪里？请高手指教

在jsp页面上处理上传要用smart.initialize(pageContext) ;这个跟servlet有点不同



<%@ page contentType="text/html; charset=GBK"%>
<jsp:useBean id="smart" scope="page" class="org.lxh.smart.SmartUpload"/>
<%
// 1、上传初始化
request.setCharacterEncoding("GBK");
smart.initialize(pageContext) ;
smart.setMaxFileSize(1000000111);
smart.setTotalMaxFileSize(900000001);
// smart.setAllowedFilesList("jpg,txt,doc,exe,gif,bmp,mp3");
smart.setDeniedFilesList("jsp,html,php,aspx,asp");
// 2、准备上传
smart.upload() ;
// 3、保存上传的文件
// smart.save("/upload") ;
int count=smart.getFiles().getCount();
out.println("<font>"+count+"</font>个文件上传成功<br>");
for(int i=0;i<count;i++)
{
//这里要输入org.lxh.smart.因为这里要指明是哪里的File
org.lxh.smart.File file=smart.getFiles().getFile(i);

String name = smart.getRequest().getParameter("name"+i) ;
String ext = smart.getFiles().getFile(i).getFileExt() ;
file.saveAs("/upload/"+name+"."+ext) ;
out.println("<center>");
out.println("<table border=1>");
out.println("<tr><td>表单项名"+file.getFieldName()+"</td></tr>");
out.println("<tr><td>文件长度"+file.getSize()+"</td></tr>");
out.println("<tr><td>文件扩展名"+file.getFileExt()+"</td></tr>");
out.println("<tr><td>文件全名"+file.getFilePathName()+"</td></tr>");
out.println("<tr><td><img src=./upload/"+name+"."+ext+" height=250 width=200></tr></td>");
out.println("</table>");
out.println("</center>");


}
//不能直接用request

这是我做的一个传多张照片的，在servlet里要加上
ServletConfig config;
public void init(ServletConfig config) throws ServletException
{
this.config=config;
}

smart.initialize(config, request, response);//初始化







源代码
package Servlet;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import Bean.*;
import Entity.*;
import org.lxh.smart.SmartUpload;
import org.lxh.smart.*;
public class ImageDealServlet extends HttpServlet {
public ImageDealServlet() {

}

private static final String CONTENT_TYPE = "text/html; charset=GBK";

ServletConfig config;
public void init(ServletConfig config) throws ServletException
{
this.config=config;
}

//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException
{
try
{
String flag=request.getParameter("flag");
if(flag.equals("addImage"))
{

response.setContentType(CONTENT_TYPE);
SmartUpload smart = new SmartUpload();
// 1、上传初始化
smart.initialize(config, request, response);
smart.setMaxFileSize(1000000111);
smart.setTotalMaxFileSize(900000001);
// smart.setAllowedFilesList("jpg,txt,doc,exe,gif,bmp,mp3");
smart.setDeniedFilesList("jsp,html,php,aspx,asp");
// 2、准备上传
smart.upload();
// 3、保存上传的文件
// smart.save("/upload") ;
int count = smart.getFiles().getCount();
System.out.println("上传" + count + "个文件上传");
boolean suc = false;
for (int i = 1; i <=count; i++)
{
//这里要输入org.lxh.smart.因为这里要指明是哪里的File
org.lxh.smart.File file = smart.getFiles().getFile(i-1);
String description =smart.getRequest().getParameter("description"+i);
String fileName = smart.getFiles().getFile(i-1).getFileName();
String ext = smart.getFiles().getFile(i-1).getFileExt();
file.saveAs("/upload1/" + fileName+i+ "." + ext);
ImageDAO imageDao = new ImageDAO();
if(imageDao.insertImage("./upload1/" + fileName+i+ "." + ext,description))
{
suc=true;
}
else
{
suc=false;
break;
}

}
if(suc)
{
System.out.println("文件上传成功");
}
else
{
System.out.println("文件上传失败");
}
}//end if flag.equals("addImage")
else if(flag.equals("getImage"))
{
ImageDAO imageDao = new ImageDAO();
String idd=request.getParameter("id");
ArrayList array=null;
int pageCount=imageDao.getPageCount();
if(idd==null)
{
array=imageDao.getImgageInfo();
}
else
{
int id=Integer.parseInt(request.getParameter("id"));
if(id==0)
{
array=imageDao.getImgageInfo();
}
else
{
array=imageDao.getImageInfoById(id);
}

}

request.setAttribute("imageInfo",array);
request.setAttribute("get","true");
request.getRequestDispatcher("scanimage.jsp").forward(request,response);
}

}
catch (Exception ex)
{
ex.printStackTrace();
}


}

//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
doGet(request, response);
}

//Clean up resources
public void destroy() {
}

private void jbInit() throws Exception {
}
}
