我想发送一封包含JavaMail的电子邮件，但每次我都会收到异常。我创建了一个JFrame项目，并为按钮创建了一个actionevent：
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
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() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("xyz@gmail.com", "###");
}
}
);
//I've tried also this version of the Session:
//Session session = Session.getInstance(props,new NewEmpty("xyz@gmail.com","###"));
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("xyz@gmail.com"));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("zyx@gmail.com"));
message.setSubject("Hi");
message.setText("Helló!");
Transport.send(message);
JOptionPane.showMessageDialog(null, "Sent!");
}catch(Exception e) {
JOptionPane.showMessageDialog(null, e);
}
}
}
例外是：
