Spring - Hiber. Transaction is not working...

Hi all,

I have a problem with Spring and Hibernate. I have defined a facade and some DAO�s with a transactional behaviour, but they�re not working in a transactional way.

This is my Spring applicationContex:

...

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource"><ref local="MyDataSource"/></property>
<property name="mappingResources">
<list>
....
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">...</prop>
<prop key="hibernate.show_sql">..</prop>
</props>
</property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory"><ref local="sessionFactory"/></property>
</bean>

<!-- DAO�S -->
<bean id="UserDao" class="com.....UserDaoImpl">
<property name="sessionFactory"><ref local="sessionFactory"/></property>
</bean>

<bean id="PlantaDao" class="com.....PlantaDaoImpl">
<property name="sessionFactory"><ref local="sessionFactory"/></property>
</bean>

... more Dao�s ...


<bean id="FacadeDaoTarget" class="....FacadeDaoImpl">
<property name="userDao">
<ref local="UserDao"/>
</property>
<property name="plantaDao">
<ref local="PlantaDao"/>
</property>
... more Dao�s ...
</bean>

<bean id="MyTransactionalDAO" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager"><ref local="transactionManager"/></property>
<property name="target"><ref local="FacadeDaoTarget"/></property>
<property name="transactionAttributes">
<props>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="load*">PROPAGATION_REQUIRED,readOnly</prop>
<!-- Transaccionales -->
<prop key="add*">PROPAGATION_REQUIRED</prop>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>


Well, I think that�s OK configured, but when I execute a transactional operation against any DAO, that is not transactional at all.

For example, in UserDaoImpl:

public Long saveUser(User user, Work work) throws DataAccessException, java.sql.SQLException
{
Long id = (Long)getHibernateTemplate().save(user);
if(true) throw new SqlException("My Exception");
}

If I force to fail it, the user is saved. Even if i don�t cast any exception and the method fails due to a real exception, there is not Transacional behaviour.


Please help...
What I�m doing wrong??
Can you help me??

Thanks in advance and forgive my terrible English
