Principle: The message can be seen as a number of parts, such as the body is a part of the attachment is a part, so use BodyPart to set the format of the message
Message.addrecipient (message.recipienttype.to,new internetaddress (mail_to));
BodyPart Messagebodypart = new MimeBodyPart ();
Messagebodypart.settext ("Pardon Ideas");
Multipart Multipart = new Mimemultipart ();
Multipart.addbodypart (Messagebodypart);
Messagebodypart = new MimeBodyPart ();
DataSource Source = new Filedatasource ("./20020423/test.zip")//set of attachments for messages
Messagebodypart.setdatahandler (new DataHandler (source));
Messagebodypart.setfilename ("Test.zip");
Multipart.addbodypart (Messagebodypart);
Message.setcontent (multipart);
Transport.send (message);
System.out.println ("Send ok!");
}
catch (Exception ex)
{
System.out.println ("Faild" +ex);
}
}
This piece of code is used to send messages with attachments
void Jbutton6_actionperformed (ActionEvent e) {
Try
{
Properties props = System.getproperties ();
Authenticator auth = new Email_autherticator ();
Props.put ("Mail.smtp.host", host);
Props.put ("Mail.smtp.auth", "true");
Session session = Session.getdefaultinstance (Props,auth); Establish session
Store store = Session.getstore ("POP3");
Store.connect (Host,username,password);
After connecting to the store,you can get a Folder,which must is opened before you can read messages from it:
Folder folder = Store.getfolder ("INBOX");
Folder.open (Folder.read_write);
Message message[] = Folder.getmessages ();
for (int i=0,n=message.length;i {
Get part of the message, such as head information, the sender's signature, the messenger's e-mail address.
String Out_from_person = ((internetaddress) message[i].getfrom () [0]). getpersonal ();
String out_from_address = ((internetaddress) message[i].getfrom () [0]). getaddress ();
System.out.println ("From:" +out_from_person+ ")";
