How to send email based on listener outputs in AEM?

I've got this listener which listens to any changes including addition, modification and deletion for nodes under content directory. A mail has to be send to some mail address whenever the listener logs a change. How to work around that?

import javax.jcr.RepositoryException; 
import javax.jcr.Session;
import javax.jcr.observation.Event;
import javax.jcr.observation.EventListener;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Deactivate;
import org.osgi.service.component.annotations.Reference;
import com.day.cq.mailer.MessageGatewayService;
import org.osgi.service.component.ComponentContext; 
import javax.jcr.observation.EventIterator ; 
  
@Component(immediate=true,
service= EventListener.class)
  
public class ContentChangeListener implements EventListener{
  
     private Session adminSession;
       
      
     @Reference
     org.apache.sling.jcr.api.SlingRepository repository;
     
     @Reference
     private MessageGatewayService messageGatewayService;
       
     @Activate
     public void activate(ComponentContext context) throws Exception {
     System.out.println("Started Listener");
     try {
         adminSession = repository.loginService("testing",null);
         adminSession.getWorkspace().getObservationManager().addEventListener(
          this, Event.PROPERTY_ADDED|Event.NODE_ADDED|Event.NODE_MOVED|Event.NODE_REMOVED|Event.PROPERTY_CHANGED|Event.PROPERTY_REMOVED, 
          "/content/silversea/en/homepage", true, null, null, false);
       
           
     } catch (RepositoryException e){
      System.out.println("unable to register session"+e);
     }
    }
    @Deactivate
    public void deactivate(){
     if (adminSession != null){
      adminSession.logout();
     }
    }
       
    public void onEvent(EventIterator eventIterator) {
      try {
        while (eventIterator.hasNext()){
       
        System.out.println("Something has been added : {}"+ eventIterator.nextEvent().getPath());
        }
       } catch(RepositoryException e){
       System.out.println("Error while treating events"+e);
      }
     }
    }

Hi jezwn​

Add following code in your Activate method and modify variables accordingly. I have configured gmail for sending the mails.​

String sender_mail = YOUR_EMAIL_ADDRESS;
String sender_pass = YOUR_PASSWORD;
String host = "smtp.gmail.com";
int port    = 587;
String recipient_mail = 'email@address.com';
String mail_subject = "Test Subject";
String mail_content = "This is sample email content";
java.util.Properties props = new java.util.Properties();
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", port);
props.put("mail.smtp.starttls.enable", true);
props.put("mail.smtp.auth", true);
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(sender_mail, sender_pass);
    }
});
try {
    MimeMessage msg = new MimeMessage(session);
    InternetAddress[] address = InternetAddress.parse(recipient_mail, true);
    msg.setRecipients(Message.RecipientType.TO, address);
    String timeStamp = new SimpleDateFormat("yyyymmdd_hh-mm-ss").format(new Date());
    msg.setSubject(mail_subject);
    msg.setSentDate(new Date());
    msg.setText(mail_content);
    msg.setHeader("XPriority", "1");
    Transport.send(msg);
    LOGGER.info("Mail has been sent successfully");
} catch (MessagingException mex) {
    LOGGER.info("Unable to send an email: " + mex);
}


Don't forget to import libraries

Hope it helps!
