Hello,

I am a newbie in AspectJ and Hibernate and have been working on writing a aspect ( using aspectj) which basically calls openSession and closeSession from a HibernateUtil class. Somehow, the pointcut in aspect program never gets invoked. Can anyone help me with this?

Thanks in advance

If you could post the code here, probably somebody can help. I am new to Hibernate but I have been using AspectJ for sometime now.

Thanks,

Hello Everyone and Bipin!


I have a HibernateUtil class which is an example given in HIbernate documentation. I have a aspect which upon calling any method in TopicUserAdmin.java should invoke the Hibernate session. I want the session to be available in java class. Any help on this will be great.

---------------------------------------------------------------------------------

Sample code for TopicUserAdmin

public class TopicUserAdmin{

Session session;
public String addTopic(){

//some code.
session.save();
return "success";

}

}

------------------------------------------------------------------------------------
import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
try {
// Create the SessionFactory
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (HibernateException ex) {
throw new RuntimeException("Configuration problem: " + ex.getMessage(), ex);
}
}

public static final ThreadLocal session = new ThreadLocal();

public static Session currentSession() throws HibernateException {
Session s = (Session) session.get();
// Open a new Session, if this Thread has none yet
if (s == null) {
s = sessionFactory.openSession();
session.set(s);
}
return s;
}

public static void closeSession() throws HibernateException {
Session s = (Session) session.get();
session.set(null);
if (s != null)
s.close();
}
}


-----------------------------------------------------------------------------------
package example.aspect;

import example.businessModel.TopicUserAdmin;


public aspect HibernateAspect
{

pointcut hibernateFetch(TopicUserAdmin tua) : call
(public * *.*(..)) && target(tua);

before(TopicUserAdmin tua) : hibernateFetch(tua)
{
tua.sess = HibernateHelper.openSession();
}

after(TopicUserAdmin tua) returning : hibernateFetch(tau)
{
HibernateHelper.closeSession();
}

after(TopicUserAdmin tua) throwing : hibernateFetch(tua)
{
HibernateHelper.closeSession();
}
}

This really is an AspectJ question, so probably you should have posted it to AspectJ lists.

Your pointcut is :


This pointcut does not
1. Consider the package structure of TopicUserAdmin class
2. Advises the call of add() method, rather that addTopic() method

Try fixing these issues with the pointcut and I hope that the Aspect will work for you.

Hello Binil,

Thanks a lot..Yes, I was AspectJ issue and I messed around corecting the syntax and it works. Once again, thanks.
