Injecting fields via Spring into entities loaded by Hibernate

Question

I am looking for a way to inject certain properties via Spring in a bean that is loaded from the DB by Hibernate.

E.g.

class Student {
   int id; //l

While the aspectj way works, I'd say the standard spring / hibernate way is to register a LoadEventListener (read more in the hibernate core reference, the spring reference and this thread)

here is a snip from the spring sessionfactory bean definition

    ...
    
        
    

and here is the LoadEventListener:

public class MyLoadListener implements LoadEventListener{

    public void setSpringManagedProperty(String springManagedProperty){
        this.springManagedProperty = springManagedProperty;
    }
    private String springManagedProperty;

    @Override
    public void onLoad(LoadEvent event, LoadType loadType) throws HibernateException{
        if(MyEntity.class.getName().equals(event.getEntityClassName())){
            MyEntity entity = (MyEntity) event.getInstanceToLoad();
            entity.setMyCustomProperty(springManagedProperty);
        }

    }

}

Look mom, no aspectj needed.
