使用 javamail 读取同一邮件的邮件和附件名称

Question

i need to use java to view mails. from these mails i want to know the name of the attachment (if there is one) and i want to know the message.

is it possible to not only print the name of the attachment but to also print the contents of the mail? currently i'm using the following code that get's only the name of the attachment or (if their is none) the message content.

 Message[] message = folder.getMessages();
 //Display message.
 for (int i = 0; i < message.length; i++) {

     System.out.println("------------ Message " + (i + 1) + " ------------");

     System.out.println("SentDate : " + message[i].getSentDate());
     System.out.println("From : " + message[i].getFrom()[0]);
     System.out.println("Subject : " + message[i].getSubject());


     Multipart multipart = (Multipart) message[i].getContent();

     for (int x = 0; x < multipart.getCount(); x++) {
         BodyPart bodyPart = multipart.getBodyPart(x);

         String disposition = bodyPart.getDisposition();

         if (disposition != null && (disposition.equals(BodyPart.ATTACHMENT))) {

             DataHandler handler = bodyPart.getDataHandler();
             System.out.println("Attachment : " + handler.getName());

         } else {
             System.out.println("Content: " + bodyPart.getContent());
         }
     }

Yes its possible. Try this example

Multipart mp = (Multipart)message.getContent();

for (int i=0, n=multipart.getCount(); i<n; i++) {
  Part part = multipart.getBodyPart(i));

  String disposition = part.getDisposition();

  if ((disposition != null) && 
      ((disposition.equals(Part.ATTACHMENT) || 
       (disposition.equals(Part.INLINE))) {
    saveFile(part.getFileName(), part.getInputStream());
  }
}
