在通过提供相同问题的帖子后，我编写了以下代码。但我得到以下例外：

javax.mail.MessagingException：无法连接到SMTP主机：smtp.gmail.com，port：587;嵌套异常是：java.net.ConnectException：连接超时：连接

package com.nura.mail;

import javax.mail.PasswordAuthentication;
import javax.mail.Session;

public class SendMail implements Constants {

    private final static LoggerUtil log = new LoggerUtil();

    public static void main(String receiver, String msg, String header) {

        log.addLog("Entry in SendMail");
        final String username = "sendmailnotification";
        final String password = "version5.0";

        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

        Session session = Session.getInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username, password);
                    }
                });
        try {
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(username));
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(receiver));
            message.setSubject(header);
            message.setText(msg);
            Transport.send(message);
            log.addLog("Your mail has been sent");
            log.addLog("Exit from Send Mail");
        } catch (MessagingException e) {
            log.addLog(e.getLocalizedMessage());
        }
    }
    public static void main(String[] args) {
        SendMail.main("aprodigalboy@gmail.com", "test", "test");
        System.out.println("End of the program");
    }
}
