I am trying to send mails to users when they successfully register their account i.e email verification/confirmation. However, I keep getting the errors above.
This is what the MailCreatorHelper looks like
@Service
@Slf4j
public class MailCreatorHelper {
@Autowired
JavaMailSender javaMailSender;
public static String getSiteURL(HttpServletRequest request){
String siteURL = request.getRequestURL().toString();
return siteURL.replace(request.getServletPath(), "");
}
private String setVerificationCodeForUser(){
log.info("Generating authentication code --------------------------------");
return RandomString.make(35);
}
private void setProperties(){
Properties props = new Properties();
props.setProperty("mail.host", "smtp.mailgun.org");
props.setProperty("mail.smtp.port", "587");
props.setProperty("mail.smtp.auth", "true");
props.setProperty("mail.smtp.starttls.enable", "true");
props.setProperty("mail.smtp.socketFactory.port", "587");

props.setProperty("mail.smtp.socketFactory.fallback", "false");
Authenticator auth = new SMTPAuthenticator("username", "password");
Session session = Session.getInstance(props, auth);
}

What could be wrong? I am not sending any mail in the controller rather I am doing it in the service implementation. I have gone through some couple of threads and nothing seems to work for me
