openshift上java邮件程序认证错误

Question

我正在尝试使用Java Mail API发送邮件

final String username = "[e-mail]";
final String password = "mypassword";
Properties props = new Properties();
props.put("mail.smtp.user", username);
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "25");
props.put("mail.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.EnableSSL.enable", "true");
props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.setProperty("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.port", "465");
props.setProperty("mail.smtp.socketFactory.port", "465");

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

try {
    Message message = new MimeMessage(session);
    message.setFrom(new InternetAddress(username));
    message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(clientEmail));
    message.setSubject(subject);
    message.setText("Dear "+clientName+",\n\n  "+body);

    Transport.send(message);
} catch (MessagingException e) {
    throw new RuntimeException(e);
}

它在本地运行完美，但在Openshift上提供AuthenticationFailedException。下面是openshift错误日志。

另一种解决方案：我尝试了Mailgun，而不是Gmail SMTP，它公开了其API以REST服务的形式发送邮件。对于开发人员来说，这是免费的，使用免费帐户可以发送的邮件数量有上限。它在Openshift上工作得非常好。在这里，我创建了一个使用Jersey 2的Mailgun服务的示例。x。https://gist.github.com/chhabraromit/0c0a16545dd31f471332

Answer 1

Gmail真的希望您从运行应用程序的同一台机器上的浏览器登录。当您的应用程序在openshift上运行时，这是不可能的。

您可以尝试在运行浏览器的同一台机器上运行您的应用程序，看看这是否会让Gmail相信您的应用程序也可以从其他机器登录。

Answer 2

原因：谷歌正在阻止来自未知位置的访问（应用程序正在生产）

解决方案：转到http://www.google.com/accounts/DisplayUnlockCaptcha并单击继续（这将授予注册新应用程序10分钟的访问权限）。在此之后，我的生产中的应用程序开始发送电子邮件；）
