hibernate4, spring 3: No Session found for current thread

Question

I've seen several similar questions, but none of the suggested solutions helped me.

Detail, it's a simple exemple :

File: MandatTypeBean.xml

<bean id="mandatTypeDAO" class="gestint.data.dao.impl.MandatTypeDAOImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<bean id="ActionMandatType" class="gestint.data.action.MandatTypeAction">
    <property name="mandatTypeDAO" ref="mandatTypeDAO" />
</bean>   

File: HibernateSessionFactory.xml

<bean id="sessionFactory" 
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

   <property name="dataSource">
      <ref bean="DataSource"/>
    </property>

    <property name="hibernateProperties">
         <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
            <prop key="hibernate.show_sql">true</prop>  
         </props>
    </property>


    <property name="mappingResources">
        <list>
          <value>gestint/data/model/MandatType.hbm.xml</value>
        </list>
    </property>  
</bean>

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

File: MandatTypeDAO.java

public class MandatTypeDAOImpl implements MandatTypeDAO {
private SessionFactory sessionFactory;

public SessionFactory getSessionFactory() {
    return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
     this.sessionFactory = sessionFactory;
}   

public List<MandatType> listMandatType() {      
    sessionFactory.getCurrentSession().isConnected();       

    return null;
}

}

File: MandatTypeAction.java

public class MandatTypeAction extends ActionSupport{
    private static final long serialVersionUID = 1L;

    private MandatTypeDAO mandatTypeDAO;    
    private List<MandatType> mandatList = new ArrayList<MandatType>();

    public void setMandatTypeDAO(MandatTypeDAO mandatTypeDAO) {
        this.mandatTypeDAO = mandatTypeDAO;
    }

    public List<MandatType> getMandatTypeList() {
        return mandatList;
    }

    public String listMandatType() {            
        mandatList = mandatTypeDAO.listMandatType();
        return SUCCESS;
    }

}

And my error..

When I try to acces to public List<MandatType> listMandatType() with a simple linge for testing :

sessionFactory.getCurrentSession().isConnected();

I get this error :

Somebody can help me ?

Answer 1

Add the following line in your applicationContext.xml:

<tx:annotation-driven />

Then decorate your MandateTypeAction class with @Transactional annotation and will be propagated by default (default is propagation type REQUIRED) to the called methods.

Then the transaction will be injected to the MandateTypeAction.

Answer 2

Thank's for your support ! It works,

The solutions is :

I add annotation-driven File: HibernateSessionFactory.xml

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

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

And I add the annotions to the DAO File: MandatTypeDAO.java

    @Transactional(readOnly = true)
public interface MandatTypeDAO {
    @Transactional(readOnly = true)
    List<MandatType> listMandatType();  
}

Answer 3

Why are you injecting the SessionFactory? Just use the Session directly:

@Repository
public Mydao {

   @PersistenceContext
   private Session session;

   @Transactional
   public void persist(entity e) {
       session.persist(e);
   }
}
