解决错误javax.mail.AuthenticationFailedException

Question

我不熟悉使用Java发送邮件的功能。发送电子邮件重设密码时出现错误。希望你能给我一个解决方案。

下面是我的代码：

public synchronized static boolean sendMailAdvance(String emailTo, String subject, String body)
{
    String host = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-ADDRESS");
    String userName = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-USERNAME");
    String password = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-PASSWORD");
    String port = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-PORT");
    String starttls = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-STARTTLS");
    String socketFactoryClass = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-SOCKET-CLASS");
    String fallback = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-ALLOW-FALLBACK");

    try
    {
        java.util.Properties props = null;
        props = System.getProperties();
        props.put("mail.smtp.user", userName);
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.debug", "true");

        if(!"".equals(port))
        {
            props.put("mail.smtp.port", port);
            props.put("mail.smtp.socketFactory.port", port);
        }

        if(!"".equals(starttls))
            props.put("mail.smtp.starttls.enable",starttls);

        if(!"".equals(socketFactoryClass))                   
            props.put("mail.smtp.socketFactory.class",socketFactoryClass);

        if(!"".equals(fallback))
            props.put("mail.smtp.socketFactory.fallback", fallback);

        Session session = Session.getDefaultInstance(props, null);
        session.setDebug(true);

        MimeMessage msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress(userName));
        msg.setSubject(subject);                
        msg.setText(body, "ISO-8859-1");
        msg.setSentDate(new Date());
        msg.setHeader("content-Type", "text/html;charset=\"ISO-8859-1\"");
        msg.addRecipient(Message.RecipientType.TO, new InternetAddress(emailTo));
        msg.saveChanges();

        Transport transport = session.getTransport("smtp");
        transport.connect(host, userName, password);
        transport.sendMessage(msg, msg.getAllRecipients());
        transport.close();
            return true;
    }
    catch (Exception mex)
    {
        mex.printStackTrace();
        return false;
    }
}

引发以下错误：

您应该将端口更改为587，我测试了您的代码，并且工作正常

如果仍然发生错误，请将会话变量更改为以下代码：

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