Question

try {
    InternetAddress to = new InternetAddress("tehilar20@gmail.com");
    InternetAddress from = new InternetAddress("tehilar20@gmail.com");
    String sub = new String("test");
    String body = new String("test-mail");
    MailMessage msg = new MailMessage();
    msg.setTo(to);
    msg.setFrom(from);
    msg.setBody(body);
    msg.setSubject(sub);
    MailServiceUtil.sendEmail(msg);
    MailEngine.send(from, to, sub, body);
} catch (Exception e) {
    System.out.println("can't send mail");
}

MailServiceUtil.sendEmail(msg);

这种方式不起作用

MailEngine.send(from, to, sub, body);

这种方式给了我错误：

Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1

我该怎么做才能让它发挥作用？

Answer 1

您缺少身份验证属性，请查看this以获取完整示例。

Answer 2

问题很可能是您使用没有SSL的SMTP协议进行连接。如果这是基于JavaMail的，请确保使用smtps协议，因为它是带SSL的SMTP。还要确保启用身份验证。请参阅JavaMail FAQ entry on GMail

Answer 3

您是否在邮件配置页上的“外发SMTP服务器”下选中了“使用安全网络连接”？

您还可以尝试设置“手动指定其他JavaMail属性以覆盖上述配置”。到

mail.smtp.auth=true
mail.smtp.port=465
mail.smtp.socketFactory.port=465
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.socketFactory.fallback=false

Answer 4

从Liferay发送电子邮件我建议使用消息总线。为此目的，有两个目的地临时。您可以在我的GitHub存储库中找到完整的示例。按照一段使用SubscriptionSender类的示例代码，该类继续使用消息总线。

            SubscriptionSender subscriptionSender = new SubscriptionSender();

        subscriptionSender.setSubject("Lista degli utenti disattivati");
        subscriptionSender.setBody(emailBody.toString());
        subscriptionSender.setUserId(user.getUserId());
        subscriptionSender.setCompanyId(user.getCompanyId());
        subscriptionSender.setFrom("noreply@liferay.com", "Liferay Portal");
        subscriptionSender.setHtmlFormat(false);
        subscriptionSender.setMailId("user", user.getUserId());

        subscriptionSender.addRuntimeSubscribers(
            user.getEmailAddress(),
            user.getFullName());

        List<EmailAddress> emails = (List<EmailAddress>) user.getEmailAddresses();
        if (emails.size() > 0) {
            if (_log.isInfoEnabled()) {
                _log.info("User " + user.getUserId() +
                    " has additional emails address");
            }
            for (EmailAddress emailAddress : emails) {
                subscriptionSender.addRuntimeSubscribers(
                    emailAddress.getAddress(),
                    (String) user.getFullName());

            }
        }

        subscriptionSender.flushNotificationsAsync();

以下是portal-ext.properties中的GMail配置，它对我有用多年：

mail.session.mail.pop3.host=localhost
mail.session.mail.pop3.password=
mail.session.mail.pop3.port=110
mail.session.mail.pop3.user=
mail.session.mail.smtp.auth=true
mail.session.mail.smtp.host=smtp.gmail.com
mail.session.mail.smtp.port=465
mail.session.mail.smtp.password=<MY-PASSWORD-ON-GMAIL>
mail.session.mail.smtp.user=<MY-USERNAME-ON-GMAIL-(WITHOUT-@GMAIL.COM)>
mail.session.mail.store.protocol=pop3
mail.session.mail.transport.protocol=smtp
mail.session.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.session.mail.smtp.starttls.enable=true

不能发送liferay的电子邮件
