Access to Session using Spring JPA and Hibernate in order to enable filters

问题

In a Spring JPA + Hibernate environment I need to enable Hibernate entity filters. So I should have access to Hibernate Session object, but I'm using EntityManagerFactory and Spring JPA magics. There is any Session interceptor so I can call the enableFilters() method on it every time Spring create a new Session?

回答1:

I ended up with AOP solution :

@Aspect
@Component
public class EnableFilterAspect {

    @AfterReturning(
            pointcut="bean(entityManagerFactory) && execution(* createEntityManager(..))",
            returning="retVal")
    public void getSessionAfter(JoinPoint joinPoint, Object retVal) {
        if (retVal != null && EntityManager.class.isInstance(retVal)) {
            Session session = ((EntityManager) retVal).unwrap(Session.class);
            session.enableFilter("myFilter").setParameter("myParameter", "myValue");
        }
    }

}

here's one i use for apps that support is_delete on objects -

    entityManager.unwrap(Session.class)
            .enableFilter("notDeleted")
            .setParameter("isDeleted", false);
