Summary of JavaMail Operations (4)

This piece of code is used to send messages with HTML information
void Jbutton8_actionperformed (ActionEvent e) {
Try
{
Properties Props = new properties ();
Authenticator auth = new Email_autherticator ();
Props.put ("Mail.smtp.host", host);
Props.put ("Mail.smtp.auth", "true");
Session session = Session.getdefaultinstance (Props,auth);
MimeMessage message = new MimeMessage (session);
Set the message body
String htmltext= "< h1>helloMessage.setcontent (HTMLText, "text/html");//text/plain set the format of the message because it has an HTML document, the text/html format

Message.setsubject (Mail_subject);
Message.settext (mail_body); When using message.setcontent (), it seems impossible to use Message.settext ()
Message.setheader (Mail_head_name,mail_head_value);
Message.setsentdate (New Date ());
Address = new InternetAddress (Mail_from, "sunxiaoming");
Message.setfrom (address);
Address toaddress = new internetaddress (mail_to);
Message.addrecipient (message.recipienttype.to,toaddress);
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 pictures
void Jbutton9_actionperformed (ActionEvent e) {
Try
{
String file = "./20020423/test.gif";
Properties Props = new properties ();
Authenticator auth = new Email_autherticator ();

Props.put ("Mail.smtp.host", host);
Props.put ("Mail.smtp.auth", "true");
Session session = Session.getdefaultinstance (Props,auth);
MimeMessage message = new MimeMessage (session);

Message.setsubject ("Embedded Image");
Address = new InternetAddress (Mail_from, "sunxiaoming");
Message.setfrom (address);
Address toaddress = new internetaddress (mail_to);
Message.addrecipient (message.recipienttype.to,toaddress);
Message.setheader (Mail_head_name,mail_head_value);
Message.setsentdate (New Date ());

BodyPart Messagebodypart = new MimeBodyPart ();
String HTMLText = "< h1>Messagebodypart.setcontent (HTMLText, "text/html");
The principle is the same as sending attachments, the message is considered to be composed of several parts, first set each part, and then all of them together.
Create a related multi-part to combine the parts
Mimemultipart multipart = new Mimemultipart ("related");
Multipart.addbodypart (Messagebodypart);

Create part for the image
Messagebodypart = new MimeBodyPart ();

Fetch the image and associate to part
DataSource FDS = new Filedatasource (file);
Messagebodypart.setdatahandler (New DataHandler (FDS));
Messagebodypart.setheader ("Content-id", "Memememe");

ADD part to Multi-part
Multipart.addbodypart (Messagebodypart);

Associate multi-part with Message
Message.setcontent (multipart);

Transport.send (message);
System.out.println ("Send ok!");
}
catch (Exception ex)
{
System.out.println ("Faild" +ex);
}

}

This program is used to accept messages with HTML information
void Jbutton7_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);
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//for (int i=0,n=1;i {
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+ ")";
SYSTEM.OUT.PRINTLN ("Address:" +out_from_address+ ");

String out_subject = Message[i].getsubject ();
System.out.println ("Subject:" +out_subject+ ")";

Get information about a message and manipulate each part of it
Part messagepart = Message[i];
Object out_content = Messagepart.getcontent ();
if (out_content instanceof Multipart)
{
MessagePart = ((Multipart) out_content). Getbodypart (0);
System.out.println ("[Multipart message]");
}
String Out_content_type = Messagepart.getcontenttype ();
System.out.println ("CONTENT:" +out_content_type);

Jeditorpane1.settext ("");//show it on Jeditorpanel
Jeditorpane1.setcontenttype ("text/html");
Jeditorpane1.settext ((String) out_content);
Jeditorpane1.seteditable (FALSE);

/*
if (Out_content_type.startswith ("Text/plain") | | | out_content_type.startswith ("text/html")
{
InputStream ipstm = Messagepart.getinputstream ();
BufferedReader bufreader = new BufferedReader (new InputStreamReader (ipstm));
String thisline = Bufreader.readline ();
while (Thisline!= null)
{
System.out.println ("Thisline:" +thisline);
Thisline = Bufreader.readline ();
}
}
*/
System.out.println ("------------------------------------------------------------");
Message[i].setflag (flags.flag.deleted,true);
}
Folder.close (TRUE);
Store.close ();
}
catch (Exception ej2)
{
System.out.println (EJ2);
}
