java.lang.RuntimeException : javax.mail.MessagingException : [EOF] (javax.mail.MessagingException : [EOF]에 의해 발생한다)

javax.mail을 사용하여 간단한 메일 발신자를 작성하려고합니다.

MailService :

@Service
public class MailServiceImpl implements MailService {
    private String username;
    private String password;
    private Properties properties;

    private MailServiceImpl() {
        this.username ="my@gmail.com";
        this.password = "my";
        properties = new Properties();
        properties.put("mail.smtp.host", "smtp.gmail.com");
        properties.put("mail.smtp.socketFactory.port", "465");
        properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.put("mail.smtp.auth", "true");
        properties.put("mail.smtp.port", "465");
    }

    @Override
    public void sendMail(String to, String subject, String body) {
        Session session = Session.getInstance(properties, new 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(to));
            message.setSubject(subject);
            message.setText(body);
            Transport.send(message);
        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

매개 변수 :

 public static final String TOPIC_REGISTRATION = "REGISTRATION";
 public static final String NOTIFICATION_MESSAGE = "Thank you for registration";

 mailService.sendMail(userMail,TOPIC_REGISTRATION,NOTIFICATION_MESSAGE);

의문: 왜이 문제가 있으며이 문제를 해결하는 방법은 무엇입니까?

나는 그것이 매우 대중적인 질문이라는 것을 알고 있었지만 해결책을 찾을 수 없다.

편집하다:

@Service
public class MailServiceImpl implements MailService {
    private String username;
    private String password;
    private Properties properties;

    private MailServiceImpl() {
        this.username ="my@gmail.com";
        this.password = "my";
        properties = new Properties();
        properties.put("mail.smtp.host", "imap.gmail.com");
        properties.put("mail.smtp.auth", "true");
        properties.put("mail.smtp.port", "465");
        properties.put("mail.smtp.ssl.enable", "true");
    }

    @Override
    public void sendMail(String to, String subject, String body) {
        String host = "imap.gmail.com";
        Properties props = new Properties();
        Session session = Session.getInstance(props);
        Store store = null;
        try {
            store = session.getStore("imap");
            store.connect(host, username, password);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

2.다음 등록 정보를 추가하십시오.

다음 등록 정보를 추가하십시오.

properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.port", "465");

작동하지 않으면 포트를 변경하십시오.

properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.smtp.port", "587");
