Question

我以前用过的代码，但现在开始失败了，我的猜测是服务器上的某些内容已被更改，可能是权限或其他内容。我需要弄清楚它可能是什么来修复。

基本上我有：

将文件发送到服务器的POST请求
文件通过电子邮件发送为附件

以下是准备Mimeparts的代码

DiskFileItemFactory factory = new DiskFileItemFactory();        
ServletFileUpload upload = new ServletFileUpload(factory);

//parse request
List<?> items = upload.parseRequest(request);

HashMap<String, FileItem> form = new HashMap<String, FileItem>(); 

Iterator<?> iterator = items.iterator();
while (iterator.hasNext()) {
    FileItem item = (FileItem) iterator.next();           
    form.put(item.getFieldName(), item);
}


//handle attachment
if(form.containsKey("uploaded_file"))
{
    FileItem fileItem = form.get("uploaded_file");
    String fileName = fileItem.getName();
  File f = new File(fileName);
    try {
        InputStream inputStream = fileItem.getInputStream();

        OutputStream out=new FileOutputStream(f);
        byte buf[]=new byte[1024];
        int len;
        while((len=inputStream.read(buf))>0)
            out.write(buf,0,len);

        out.close();
        inputStream.close();

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

    MimeBodyPart attachment = new MimeBodyPart();
    attachment.setDataHandler(new DataHandler(new FileDataSource(f)));
    attachment.setFileName(fileName);
}



//below I use a javax.mail.Transport to send it via email      
//mimeparts : new MimeBodyPart[]{attachment}

用于正常工作的代码，刚刚开始抛出此异常：


    javax.mail.MessagingException: IOException while sending message;
      nested exception is:
        java.io.FileNotFoundException: uploaded_file_name.zip (Permission denied)
        com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:1141)
        javax.mail.Transport.send0(Transport.java:195)
        javax.mail.Transport.send(Transport.java:124)

使用电子邮件附件的Tomcat文件上载失败 - 权限被拒绝
