Java 邮件 - 电子邮件未通过 Gmail 发送

Java Mail - Email Not Sending through Gmail

我正在尝试执行以下代码集,但无济于事。为此,我正在使用我的 Gmail 帐户。我已禁用两步验证并允许启用安全性较低的应用程序,但我一直收到错误消息:

javax.mail.AuthenticationFailedException: 534-5.7.14

public void sendEmail()
{
    try
    {
        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");

        Session session = Session.getInstance(props, new javax.mail.Authenticator()
        {
            protected PasswordAuthentication getPasswordAuthentication()
            {
                return new PasswordAuthentication("example@gmail.com", "password");
            }
        });

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("example@gmail.com"));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("example@company.com"));
        message.setSubject("Testing Subject");
        message.setText("Testing Text");

        Transport.send(message);

        System.out.println("Mail Sent!");

    } 

    catch (Exception ex)
    {
        ex.printStackTrace();
    }
}

我需要做的就是启用两步验证,然后为应用程序生成一个应用程序密码。感谢大家的回应。 :)
