Question

我正在尝试从java servlet向gmail发送自动邮件。我使用了以下类。

UITableView

我有一个servlet，我试图在一个类EmailTest中调用函数sendEmail。

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;


public class EmailTest {

public void sendEmail(){
    String to="toid@gmail.com";
    String host="mail.javatpoint.com";
    final String user="fromid@gmail.com";
    final String password="password";
    //Get the session object
    Properties props = new Properties();
    props.put("mail.smtp.host",host);
    props.put("mail.smtp.auth", "true");
    System.out.println("here");
    Session session = Session.getDefaultInstance(props,
            new Authenticator() {

                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(user,password);
                }
            });

    //Compose the message
    System.out.println("here");
        MimeMessage message = new MimeMessage(session);
    try {
        message.setFrom(new InternetAddress(user));

    message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
        message.setSubject("javatpoint");
        message.setText("This is simple program of sending email using JavaMail API");

        //send the message
        Transport.send(message);

        System.out.println("message sent successfully...");
    } catch (MessagingException e) {
        e.printStackTrace();
    }


}

}

但问题是它没有显示任何错误，也没有发送任何邮件。我该如何解决这个问题？
