修复javax.mail.AuthenticationFailedException异常的异常 [英] Exception to fix javax.mail.AuthenticationFailedException exception

问题描述

我正在学习如何使用javamail API发送电子邮件，我已经创建了必要的属性和说明，以便使用SMTP服务器发送简单的电子邮件，并且我正在使用以下代码:

I am learning how to send an email with javamail API, i have created the necessary properties and instructions to send a simple email using SMTP server, and i am using this code :

     Properties props=new Properties();
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.port", "465");

    Session session= Session.getDefaultInstance(props, new javax.mail.Authenticator() {

    protected PasswordAuthentication getpPasswordAuthentication(){
    return new  PasswordAuthentication("[e-mail]", "password");
    }


    });
    try{
        Message message=new MimeMessage(session);
        message.setFrom(new InternetAddress("myemail"));    
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("recepientemailadresse"));
        message.setSubject("the java mail test");
        message.setText("Guess what brother the java mail is working correctly");
        Transport.send(message);
         JOptionPane.showMessageDialog(rootPane, "message sent");
    }
    catch(Exception e){
        JOptionPane.showMessageDialog(rootPane, e);
         e.printStackTrace();
    }

并且在运行时发生异常，提到:

and i the run time an exception occurred mentioning that :
