Why this No Session found for current thread exceptions in spring 3.1 and hibernate 4

Question

I was trying to configure spring 3.1 and hibernate. I have written a simple test project. where I have user domain and userDao and its implementation

let me show you may appliationContext

            <prop key="hibernate.query.substitutions">true=1 false=0</prop>
        </props>
    </property>
</bean>

and part of UserDaoImpl

 @Repository 
public class UserDaoImpl implements UserDao {

@Autowired
private SessionFactory sessionFactory;

@Override
public User getUser(Long userId) {
    if (userId != null && userId > 0) {
        return (User) sessionFactory.getCurrentSession().get(User.class,
                userId);
    }
    return null;
}

@Override
public void updateUser(User user) {
    if (user != null) {
        sessionFactory.getCurrentSession().update(user);
    }
}

it seems alright. But when I was trying to run my test cases I'm this exceptions.

Any kind of help is appreciated.

Thanks

EDIT:

Previous problem is solved, I have got another problem : now I'm getting

Answer 1

You must set the propagation "REQUIRED" like this:

<tx:advice id="txAdvice" transaction-manager="txManager">
    <tx:attributes>
        <tx:method name="get*" read-only="true" propagation="REQUIRED"/>
        <tx:method name="*" propagation="REQUIRED"/>
    </tx:attributes>
</tx:advice>

I do not know whether this is a spring bug.

Answer 2

There are no transactions in your sample project. Add:

<tx:annotation-driven />

And annotate your DAO with @Transactional:

@Transactional
@Repository 
public class UserDaoImpl implements UserDao

Two notes:

• you are correctly marking your DAO with @Repository, but it only handles exception translation:

  A class thus annotated is eligible for Spring DataAccessException translation

• consider placing @Transactional on higher level classes (@Services), see What is the right way to use spring MVC with Hibernate in DAO, sevice layer architecture for discussion

Answer 3

update to the latest jar. Their was jira created.

https://jira.springsource.org/browse/SPR-8776
