无法使用Java程序向gmail帐户发送邮件，它会给AuthenticationFailedException根本原因：
javax.mail.SendFailedException: Sending failed;
nested exception is:
class javax.mail.AuthenticationFailedException
at javax.mail.Transport.send0(Transport.java:218)
at javax.mail.Transport.send(Transport.java:80)
at com.sekhar.mail.SendMail.<init>(SendMail.java:32)
at com.sekhar.mail.SendMail.main(SendMail.java:48)
点击此处的程序：
public class SendMail {
public SendMail() {
// TODO Auto-generated constructor stub
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
try {
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props,auth);
MimeMessage msg = new MimeMessage(session);
msg.setSubject("Open");
msg.setFrom(new InternetAddress("***@gmail.com"));
msg.setRecipient(Message.RecipientType.TO, new InternetAddress("***@gmail.com"));
msg.setText("How are you");
Transport.send(msg);
System.out.println("Mail Delivered......");
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
private class SMTPAuthenticator extends Authenticator{
public PasswordAuthentication getPasswordAuthentication(){
return new PasswordAuthentication("***@gmail.com","****");
}
}
public static void main(String[] args) {
SendMail mail = new SendMail();
}
}
