Email 如何从openshift服务器内部通过gmail帐户使用javamail发送电子邮件？

email gmail openshift

Email 如何从openshift服务器内部通过gmail帐户使用javamail发送电子邮件？,email,gmail,jakarta-mail,openshift,Email,Gmail,Jakarta Mail,Openshift,我有一个在Openshift Free（redhat webhotel）运行的Web应用程序。 通过这个应用，我想用javax.mail-api通过我的gmail帐户发送一封电子邮件。 当我尝试从我的开发人员机器上运行代码尝试时，无论使用SSL还是不使用SSL，都可以正常工作。 但是，当我从openshift服务器中的JSP页面运行它时，它就不起作用了。我从gmail上得到回复： 534-5.7.14 <https://accounts.google.com/ContinueSignIn?

下面是使用SSL的代码：

public static void sendGmail(String to, String subject, String text) throws AddressException, MessagingException
{
    String host = "smtp.gmail.com";
    final String GMAIL_USERNAME = "xxx@gmail.com";
    final String GMAIL_PASSWORD = "xxx";

    Properties props = new Properties();
    props.put("mail.smtps.host", host);
    props.put("mail.smtps.auth", "true");
    Session session = Session.getInstance(props, null);
    session.setDebug(true);
    MimeMessage msg = new MimeMessage(session);
    msg.setSubject(subject);
    msg.setText(text);
    msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
    msg.setFrom(new InternetAddress(username));
    msg.setHeader("X-Mailer", "smtpsend");
        msg.setSentDate(new Date());

        SMTPTransport t = (SMTPTransport)session.getTransport("smtps");

    try
    {
        t.connect(host, username, password);
        t.sendMessage(msg, msg.getAllRecipients());
    } 
    finally
    {
        t.close();
    }
}
如您所见，我在会话的调试模式下运行尝试，因此下面是我尝试的输出：
