如何获得jsp中file表单的值

yizhizouxiaqu 2009-05-24 10:47:30

我在做一个java mail 的客户端，想从表单上获得文件的路径，但是取得的总是文件的名字，我使用的是jspsmart，请大家帮帮忙！！
代码如下：
写邮件的：



<%@ page contentType="text/html; charset=utf-8" %>

<html>

	<head>

		<title>

			写邮件内容

		</title>

	

	</head>

	

	<body>

		<form enctype="multipart/form-data" action="sendmailFile.jsp" name="form1" method="post">

			<table width="400" border="1" align="center" cellpadding="1">

				<tr>

					<td width="34%">收信人地址:</td>

					<td width="68%">

					<input name="to" type="text" id="to">

					</td>

				</tr>

				<tr>

					<td>主题:</td>

					<td>

					<input name="title" type="text" id="title">

					</td>

				</tr>

				<tr>

					<td>

					 <label>

		              <input type="file" name="uploadfile"  id="file"/> 

		             </label>

					</td>

				</tr>

				<tr>

					<td height="1" colspan="2">

						<textarea name="content" rows="25" cols="70" id="content">

						</textarea>

					</td>

				</tr>

				<tr align="center">

					<td colspan="2" >

						<input type="submit" name="Submit" value="发送">

						<input type="reset" name="Submit2" value="重输">

					</td>

				</tr>

			</table>

		</form>

	</body>

</html>

处理邮件的：



<%@ page contentType="text/html; charset=utf-8" %>

<%@ page import="java.util.*,javax.mail.*" %>

<%@ page import="javax.mail.internet.*" %>

<%@ page import="javax.activation.*" %>

<%@ page import="java.net.*" %>



<%@ page import="com.jspsmart.upload.*" %>

<%@page import="com.jspsmart.upload.File"%>

<%@page import="java.io.InputStream"%>



<%!

	public String codeToString(String str)

	{

		String s=str;

		try

		{

			byte tempB[] = s.getBytes("utf-8");

			s = new String(tempB);

			return s;

		}

		catch(Exception e)

		{

			return s;

		}

	}

 %>

 

 

  

<html>

	<head>

		<meta http-equiv="Content-Type" content="text/html;charset=utf-8">

		<title>发送邮件的结果</title>

	</head>

	<body>

				//由邮件会话新建的一个消息对象

				MimeMessage message = new MimeMessage(s);

				

				//设置邮件

				InternetAddress from = new InternetAddress("xdh4025@sina.com");

				message.setFrom(from);

				

				InternetAddress to = new InternetAddress(to_mail);

				message.setRecipient(Message.RecipientType.TO,to);

				message.setSubject(to_title);				

				message.setSentDate(new Date());

				

				BodyPart mdp = new MimeBodyPart();

				mdp.setContent(MimeUtility.encodeText(to_content), "text/html;charset=gb2312");

				Multipart mm = new MimeMultipart();

				mm.addBodyPart(mdp);

				mdp = new MimeBodyPart();

				DataHandler dh = new DataHandler("javamail附件测试","text/plain;charset=utf-8");

				mdp.setFileName("fj.txt");

				mdp.setDataHandler(dh);

				mm.addBodyPart(mdp);

				

				mdp = new MimeBodyPart();

				

				

				String filename = null;

				

				for(int i=0; i<su.getFiles().getCount(); i++)

				{

					

					File file = su.getFiles().getFile(i);

					filename = file.getFilePathName();

					System.out.println("路径名称："+filename);

				}

			

				String filePath = request.getParameter("uploadfile");

				String ss = application.getRealPath("uploadfile");

				



				FileDataSource fds = new FileDataSource(filePath);

				

				dh = new DataHandler(fds);

				mdp.setFileName("story.txt");

				mdp.setDataHandler(dh);

				mm.addBodyPart(mdp);

				message.setContent(mm);

				message.saveChanges();

				

				Transport transport = s.getTransport("smtp");

				transport.connect("smtp.sina.com", "xdh4025", "123456");

				transport.sendMessage(message, message.getAllRecipients());

				transport.close();

谢谢各位，这个应该先上传到服务器指定的文件夹上，然后再取出来！！

你首先要上传成功才可以获取到路径

请问那我如何才能上传成功呢，
我已经使用了su.upload();

看看你有没有上传到对应服务器的位置不就可以了！
