hibernate 4 spring 4: On Lazy loading - Could not obtain transaction-synchronized Session for current thread - spring

Question

I added aspect advice to lazy loading for init session.
After migrating to Spring 4, Hibernate 4, Java 8 got exception:
org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
Hibernate config:
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="reattachSessionAspect" class="prj.ReattachSessionAspect" factory-method="aspectOf"/>
<bean class="org.springframework.transaction.aspectj.AnnotationTransactionAspect" factory-method="aspectOf"/>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan">
<list>
// model packages
</list>
</property>
<property name="hibernateProperties">

Aspect class (exception caused by sessionFactory.getCurrentSession()):
#Aspect
public class Aspect {
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
private static ThreadLocal<Boolean> LOCK = new ThreadLocal<Boolean>();
#Around("reattachSession()")
public Object reattachSession(ProceedingJoinPoint pjp) throws Throwable {
Object obj = pjp.proceed();
if (obj instanceof AbstractPersistentCollection) {
AbstractPersistentCollection ps = (AbstractPersistentCollection) obj;
Field field = getClass(ps.getClass()).getDeclaredField("session");
field.setAccessible(true);
SessionImpl o = (SessionImpl)field.get(ps);
if (!ps.wasInitialized() && (o == null || o.isClosed()) && (LOCK.get()==null || !LOCK.get())) {
LOCK.set(true);
Transaction t = null;
try {
Session session = sessionFactory.getCurrentSession();
t = session.beginTransaction();
session.update(pjp.getTarget());
Hibernate.initialize(ps);
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
if (t != null && t.isActive()) {
t.rollback();
}
throw new RuntimeException(e);
} finally {
LOCK.set(false);
}
}
}
return obj;
}
private Class getClass(Class clazz) {
if(clazz.equals(AbstractPersistentCollection.class)){
return clazz;
} else {
return getClass(clazz.getSuperclass());
}
}
#Pointcut("execution(#prj.AddSession * *(..))")
public void reattachSession(){
}
}
Method that cause exception when called:
#Lazy
#Transactional(propagation = Propagation.REQUIRED)
public List<Detail> getDetails() {
return details;
}
In services layers session getting right. And before migrating all worked. Before migrating i had current_session_context_class=thread.
Can someone advise me what i doing wrong ?
