javax.mail.AuthenticationFailedException Java Mail

我做了一个小程序,将消息发送到我的电子邮件帐户.我的大多数代码似乎都运行正常.但是,当我在我的程序中命令transport.send时,我遇到了AuthenticationFailedException.我不确定为什么,因为我认为我已经正确设置了所有内容.这是我的代码.

JavaEmail.java

public static void main (String[] args) throws Exception{
                //intialize logger 
protected static Logger logger = LogManager.getLogger(JavaEmail.class.getName());

//smtp related parameters 
private static String smtpUseremail;
private static String smtpReceiverEmailAddress;
private static String smtpUserpassword;
private static String smtpPortnumber;
private static String smtpHost;

private static String emailSubject;

//stack error message variable 
private static String message;

        try {

            logger.info("-----------------------------");
            logger.info("---------Starting up---------");
            logger.info("-----------------------------");

            initialize();

            String body = "This is a test";

            logger.info("Start to connect to email server");

            sendFromGmail(smtpUseremail, smtpUserpassword, smtpReceiverEmailAddress, emailSubject, body);



           // System.out.println("error message: " + message);

            logger.info("Email Sent");


        }
        catch (Exception e){
            logger.error(e);

            // message = e.toString();

            throw e;


        }
    }

    //Setting up Email Server
    private static void sendFromGmail(String from, String pass, String to, String subject, String body) {


        Properties props = PropertiesUtil.loadProperties("main.properties");

        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", smtpHost);
        props.put("mail.smtp.port", smtpPortnumber);

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

        MimeMessage message = new MimeMessage(session);



        try{


            message.setFrom(new InternetAddress(from));

            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));


            message.setSubject(subject);

            message.setText(body);

            Transport.send(message);

            logger.info("Message has been delievered, check your mail");

        }

        catch (MessagingException e) {
            logger.error("Messaging Exception");

            throw new RuntimeException(e);
        }
    }


    //Initializing Properties
    private static void initialize() throws Exception  {

        Properties props = PropertiesUtil.loadProperties("main.properties");

        //smtp set up
        smtpPortnumber = props.getProperty("portNumber");
        smtpReceiverEmailAddress = props.getProperty("recipientEmailAddress");
        smtpUseremail = props.getProperty("userEmailAddress");
        smtpUserpassword = props.getProperty("userPassword");
        smtpHost = props.getProperty("emailHost");
        emailSubject = props.getProperty("");

    }

}

main.properties

portNumber = 465
recipientEmailAddress = my@gmail.com
userPassword = secert
userEmailAddress = my@gmail.com
emailHost = smtp.gmail.com
