You need to update the value you have in your dispercher-servlet.xml

Use the following value for session context.

<prop key="hibernate.current_session_context_class">thread</prop>

thread is short for org.hibernate.context.internal.ThreadLocalSessionContext

Please check this link for more detailed information.

When I run the code with this change, it works for me. I use Spring 3.2.2 RELEASE and Hibernate 4.2 Final in JBoss AS7 – sendon1982 Apr 02 '14 at 22:21
do u test my project ? – Mikhail Apr 03 '14 at 18:39
Yes, I used your files above. Can you please send these files and pom file? I would like to check again if you are fine with it. – sendon1982 Apr 03 '14 at 22:51
The problem was in transaction. – Mikhail Apr 04 '14 at 18:08
Other problem was constructor in Repository – Mikhail Apr 04 '14 at 18:16
Yes, you are right. I checked my codes, I did not use constructor injection, I used property Autowire myself. – sendon1982 Apr 05 '14 at 11:58
When running the codes you provided here in JBoss, it failed due to the missing configure for your HibernateSpitterDao since you put the SessionFactory in the constructor. – sendon1982 Apr 05 '14 at 11:59
I did run into that problem "No Session found for current thread" in my sample project and fixed it by using thread in "hibernate.current_session_context_class" – sendon1982 Apr 05 '14 at 12:02

You have @Transactional annotation on your saveStudent dao method but also try and create a transaction manually in your dao method do one or other like so:

@Transactional(readOnly = false)
public void savestudent(Student student) {
    Session currentSession = sessionFactory.getCurrentSession();
    currentSession.save(student);
}

Also ensure that your dao class lives within or below the package that is specified in your component-scan tag otherwise the annotations will not be picked up by spring. Alternatively you could add a bean definition for your dao in the spring wiring that will also allow spring to do something with its annotations.

I had the same problem.

I was using annotation based configuration, I have configured sessionfactory, datasource and transaction manager every thing. but I did not give @EnableTransactionManagement annotation at AppConfig class.

The code looks like below after adding the transaction annotation.

@Configuration
@ComponentScan("com.bmp.*")
@EnableWebMvc
@PropertySource("classpath:${env}.properties")
@EnableTransactionManagement
public class AppConfig {
-----
}

The above annotations resolved my problem.

Solution 1. Delete Constructor in Repository class. 2. Delete transactions in Repository class.

Please use the @Repository annotation in dao layer and @Transnational on top of save student
