Answer 1

尝试使用此代码，

final String username = "portaluniverses@gmail.com";
final String password = "xxxxx";

Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");

然后创建一个会话

Session session = Session.getInstance(props,
  new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
  });

然后发送您的电子邮件，

Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse(to));
message.setSubject(subject);
message.setText(messageText);
Transport.send(message);
