我在忘记密码电子邮件发送期间收到以下错误 err = javax.mail.AuthenticationFailedException 这是我的代码 如何解决这个问题

protected void sendMail(String email,String activationLink,String msg){

java.util.Properties properties = new java.util.Properties();
    properties.put("mail.smtp.auth", "true");
     properties.put("mail.smtp.starttls.enable", "true");
     javax.mail.Session mailSession = javax.mail.Session.getInstance(properties);




     try {
        MimeMessage message = new MimeMessage(mailSession);


        message.setContent("<h1>Below is your "+msg+" Code</h1>"
        + "<a href='"+activationLink+"'> Click here to "+msg+" your account </a> "
        + ""
        + "","text/html" );
        message.setSubject(msg);

        InternetAddress sender = new InternetAddress("email", "password");
         InternetAddress receiver = new InternetAddress(email);
        message.setFrom(sender);
        message.setRecipient(Message.RecipientType.TO, receiver);
         message.saveChanges();

        javax.mail.Transport transport = mailSession.getTransport("smtp");
        transport.connect("smtp.gmail.com", 587, "myemailaddress", "password");
         transport.sendMessage(message, message.getAllRecipients());
        transport.close();

    } catch (Exception e) {
        System.out.println("err = " + e);
     }



 }

您确定这里有正确的参数值吗:

transport.connect("smtp.gmail.com", 587, "myemailaddress", "password");
