I'm working with Spring 3.0.5,Hibernate 3.3 and generic-hibernate-dao. I've configured Hibernate SessionFactory as below:
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean?">
<property name="dataSource">
<ref local="dataSource" />
</property>
<property name="packagesToScan" value="com.xxx.re.admin.model" /> <property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.hbm2ddl.auto">validate</prop>
</props>
</property>
</bean>
<!-- Transaction manager for a single Hibernate SessionFactory? (alternative
to JTA) -->
<tx:annotation-driven />
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager?">
<property name="sessionFactory">
<ref local="sessionFactory" />
</property>
</bean>
I've created a BaseDAOImpl and extended with a domain DAO as below:
public class BaseDAOImpl<T, ID extends Serializable> extends GenericDAOImpl<T, ID> {
@Autowired @Override public void setSessionFactory(SessionFactory? sessionFactory) {
super.setSessionFactory(sessionFactory);
}
}
@Repository public class LocaleDAOImpl extends BaseDAOImpl<Locale, Long> implements LocaleDAO {
}
On accessing my spring controller (calling the dao.findAll()
) I get the following error:
org.hibernate.HibernateException?:
No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here.
Annotate your controller with
@Transactional
(or maybe some service if it is an intermediate between your controller and DAO). Service is actually a better place, otherwise you need to place<tx:annotation-driven />
in*-servlet.xml
MVC configuration file as well.I have never used this library (I personally use Spring Data JPA from Spring portfolio), but the documentation doesn't say anything about transactions, so I guess it is up to the user to configure them.
UPDATE: looking at the examples they provide seems like I am right:
