Java发送gmail

Question

我正在处理从我的应用程序发送gmail的问题，我有以下代码：

public class Notificator {

public static void main(String[] args) {
    Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class",
            "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");

    Session session = Session.getDefaultInstance(props,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("r","");
                }
            });

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("from@no-spam.com"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("to@no-spam.com"));
        message.setSubject("Testing Subject");
        message.setText("Dear Mail Crawler," +
                "\n\n No spam to my email, please!");

        Transport.send(message);

        System.out.println("Done");

    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }
}

}

我得到以下错误：线程中出现异常＆＃34; main＆＃34; java.lang.RuntimeException：javax.mail.AuthenticationFailedException：连接失败

因此我启用了安全性较低的设备，并在防火墙中启用了intellij。

编辑：是的我有正确的信誉，只是在放到这里之前删除它们。

Answer 1

您需要指定Gmail帐户详细信息（电子邮件地址和密码），否则您将始终收到授权错误。

这是我之前使用过的一个样本：

    public JavaMailSender getJavaMailSender() {
        JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();

        javaMailSender.setHost("smtp.gmail.com");
        javaMailSender.setPort(587);
        javaMailSender.setUsername("youremailaddress@gmail.com");
        javaMailSender.setPassword("GMAIL PASSWORD HERE");

        javaMailSender.setJavaMailProperties(getMailProperties());
        return javaMailSender;
    }

    private Properties getMailProperties() {
        Properties properties = new Properties();
        properties.setProperty("mail.transport.protocol", "smtp"));
        properties.setProperty("mail.smtp.auth", "true");
        properties.setProperty("mail.smtp.starttls.enable", "true");
        properties.setProperty("mail.debug", "false");
        return properties;
    }

    JavaMailSender javaMailSender = getJavaMailSender();

    private void sendEmail(){
        javaMailSender.send((MimeMessage mimeMessage) -> {
            MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true, "UTF-8");
            message.setFrom("from@no-spam.com");
            message.setTo("to@no-spam.com");
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler," +
                "\n\n No spam to my email, please!");
        });
    }
