org.hibernate.HibernateException No Session found for current thread

1. Problem Description

Spring 3.2.6

Hibernate 4.2.0 org.hibernate.HibernateException No Session found for current thread

2. Analysis:

Quoted from R1: getCurrentSession() only makes sense inside a scope of transaction. You need to declare an appropriate transaction manager, demarcate boundaries of transaction and perform data access inside it.

3. Solution:

3.1 Add configuration in application context.

<aop:aspectj-autoproxy />

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager"/>

3.2 Add Spring's @Transactional annotation

@Autowired
private SessionFactory sessionFactory;

/**
* @return session object
*/
private Session currentSession() {
return sessionFactory.getCurrentSession();
}

/**
* @param operator
*/
@Transactional
public void saveOperator(Operator operator){
currentSession().save(operator);
}
