Answer 1

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 2

update to the latest jar. Their was jira created.

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

Answer 3

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.
