OSIV with requestCycleListener

2012-03-21 Thread grazia 
Would you recommend using a requestCycleListener to implement the OSIV
pattern and storing the hibernate session in a threadlocal ? 
Any comments ? tips ?

public class MyRequestCycleListener extends AbstractRequestCycleListener {

private static final ThreadLocalSession requestCycleThread = new
ThreadLocalSession();

/** Keys for session factories that have been opened for this request */
//protected static HashSet keys = new HashSet();

public static ThreadLocalSession getRequestCycleThread() {
return requestCycleThread;
}

@Override
public void onBeginRequest(RequestCycle cycle) {

if (requestCycleThread.get() == null) {
Session session = MyRequestCycle.getHibernateSession(null); 
requestCycleThread.set(session);
 }
 }

@Override
public void onEndRequest(RequestCycle cycle) {
if (requestCycleThread.get()!= null){
MyRequestCycle.closeHibernateSessions();
requestCycleThread.set(null);
 }
}

Grazia,

Those are good lifecycle events, but consider configuring
org.hibernate.context.ManagedSessionContext and using its ThreadLocal. Then
client code can use the more conventional
SessionFactory#getCurrentSession().
