Jika kita harus mengirim email kepada seseorang dari kode Java, kita perlu memiliki akses pada beberapa kredensial server email. Ya tidak selalu.
Google telah menyediakan akses gratis ke salah satu server emailnya dan Anda dapat menggunakannya dalam kode Java. Di bawah kode tertulis jika lebih suka catatan untuk diri saya sendiri. Jadi, jika saya membutuhkannya suatu saat, Anda dapat merujuk di sini: http://www.computerbuzz.in/2014/02/how-to-send-email-in-java-using-gmail.html
private void setMailServerProperties()
{
Properties emailProperties = System.getProperties();
emailProperties.put("mail.smtp.port", "586");
emailProperties.put("mail.smtp.auth", "true");
emailProperties.put("mail.smtp.starttls.enable", "true");
mailSession = Session.getDefaultInstance(emailProperties, null);
}
private MimeMessage draftEmailMessage() throws AddressException, MessagingException
{
String[] toEmails = { "computerbuzz@gmail.com" };
String emailSubject = "Test email subject";
String emailBody = "This is an email sent by http://www.computerbuzz.in.";
MimeMessage emailMessage = new MimeMessage(mailSession);
/**
* Set the mail recipients
* */
for (int i = 0; i < toEmails.length; i++)
{
emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmails[i]));
}
emailMessage.setSubject(emailSubject);
/**
* If sending HTML mail
* */
emailMessage.setContent(emailBody, "text/html");
/**
* If sending only text mail
* */
//emailMessage.setText(emailBody);// for a text email
return emailMessage;
}
private void sendEmail() throws AddressException, MessagingException
{
/**

String fromUser = "user-email@gmail.com";
String fromUserEmailPassword = "*******";
String emailHost = "smtp.gmail.com";
Transport transport = mailSession.getTransport("smtp");
transport.connect(emailHost, fromUser, fromUserEmailPassword);
/**
