Question

I understand the similar question have been asked before here, but I couldn’t find the solution to my problem. Basically, I am trying to use JPA through Hibernate in Spring, but the data is not being persisted for some reason.Turning on debug on spring transaction reveals nothing – EntityManager open and closed, but nothing shows up as far as transaction manager concerns … I am sure I miss something big, any help is appreciated! see the following for more details.

TIA

The basic layout is as follows: class FooDaoJPA’s save function calls out entityManager.persist(object) to persist the object.

class FooServiceImpl implements the service interface by:

@Transactional(rollbackFor = DataAccessException.class,
                    readOnly = false, timeout = 30,
                    propagation = Propagation.SUPPORTS,
                    isolation = Isolation.DEFAULT)
 public void saveFoo(Foo foo) throws DataAccessException {
        fooDao.save(foo);
}

Noted that fooDao is injected by Spring IoC

Finally controller is injected a FooService and call saveFoo() to persist data.

JPA configuration

<!-- JPA Entity Manager Factory -->
<bean id="entityManagerFactory" 
          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
          p:dataSource-ref="feDataSource"/>

<!-- Transaction Config -->
<bean id="transactionManager"
          class="org.springframework.orm.jpa.JpaTransactionManager"
          p:entityManagerFactory-ref="entityManagerFactory"/>

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

Note the mode="aspectj" in your configuration. It requires additional configuration and usually you shouldn’t use it unless you understand what does it mean and why do you need it. See 10.5.6 Using @Transactional.
