Java Mail Sample

たまにしか書かないので忘れないようにメモ。

Sample Source Code

import java.util.Date;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class JavaMail {
    public static void main(String[]args){
	String to = "sample@sample.com";
	String from = "sample@example.com";
	String host = "smtp.example.com";

	Properties p = new Properties();
	p.put("mail.transport.protocol", "smtp");
	p.put("mail.smtp.host", host);

	Session session = Session.getInstance(p, null);
	try {
	    Message message = new MimeMessage(session);
	    message.setFrom(new InternetAddress(from));
	    InternetAddress[] address = {new InternetAddress(to)};
	    message.setRecipients(Message.RecipientType.TO, address);
	    message.setSubject("JavaMail API Test");
	    message.setSentDate(new Date());
	    message.setText("This is a test. Please ignore.");
	    javax.mail.Transport.send(message);
	}
	catch(Exception e){
	    e.printStackTrace();
	}
    }
}
