javax.mail.AuthenticationFailedException Java Mail

我制作了一个小程序，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，当我的代码在我的程序中命中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 = [e-mail] userPassword = secert userEmailAddress = [e-mail] emailHost = smtp.gmail.com
