Hi,
Calling entityManager.clear() seems the best approach since most of the
queries are not executed inside a transaction. But I have no idea on where I
should use it or what would be a good implementation pattern.
I mean, let's say I have a @ViewScoped with a couple of injected
@ApplicationScoped.
@ViewScoped
public class MyViewBean{
@Inject
private MyRepo1 myRepo1;
@Inject
private MyRepo2 myRepo2;
@PostConstruct
void init(){
someVar1= myRepo1.loadSomeStuff();
someVar2 = myRepo2.loadSomeStuff();
}
..
}
@ApplicationScoped
public class MyRepo1{
@PersistenceContext(unitName = "myUnit")
private EntityManager entityManager;
public List<Something> loadSomeStuff(){ //Non transactional
entityManager.createQuery(....).getResultList();
}
}
}
So, should I call entityManager.clear() after all non transactional queries
(or at least some of them)? Can I do it in some web filter?
This seems pretty basic stuff but I can't get it right...
