javax.mail.AuthenticationFailedException：如何无法通过Java发送邮件？

我正在制作一个可以发送电子邮件的Web应用程序，在此代码中，我使用yahoo邮件进行发送。

我尝试了一些解决方案，但它们没有太多帮助我：

1. 获取“ javax.mail.AuthenticationFailedException：连接失败”错误
2. javax.mail.AuthenticationFailedException：连接失败，未指定密码？

这是我的代码：

try {

        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.mail.yahoo.com"); // for gmail use smtp.gmail.com
        props.put("mail.smtp.auth", "true");
        props.put("mail.debug", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.port", "465");
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.socketFactory.fallback", "false");

        Session mailSession = Session.getInstance(props, new javax.mail.Authenticator() {

            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("[email protected]", "my_pwd");
            }
        });

        mailSession.setDebug(true); // Enable the debug mode

        Message msg = new MimeMessage(mailSession);

        //--[ Set the FROM, TO, DATE and SUBJECT fields
        msg.setFrom(new InternetAddress("[email protected]"));
        msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse("other@mail"));
        msg.setSentDate(new Date());
        msg.setSubject("Hello World!");

        //--[ Create the body of the mail
        msg.setText("Hello from my first e-mail sent with JavaMail");

        //--[ Ask the Transport class to send our mail message
        Transport.send(msg);
        return true;

    } catch (Exception E) {
        System.out.println("Oops something has gone pearshaped!");
        System.out.println(E);
        return false;
    }

这是调试代码：
