junit test with jparepository not creating object in database - spring

Question

I am starting a project using Spring 3.2.1.RELEASE, Hibernate 4.1.9.FINAL as jpa provider, spring data 1.2.0.RELEASE for repository and bitronix 2.1.3 as transaction manager. I am new to all of these technologies so I'm sorry if I'm missing some huge point.
I am running a simple unit test to create a User object in a database:
#ContextConfiguration(locations={"classpath:tests-context.xml"})
#Transactional
#TransactionConfiguration(transactionManager="transactionManager", defaultRollback=false)
#RunWith(SpringJUnit4ClassRunner.class)
public class UserTest extends AbstractTransactionalJUnit4SpringContextTests
{
#Autowired
protected UserMgmtService userService;
#Test
public void createUserTest()
{
User user = new User();
user.setFirstName("jonny");
user.setLastName("doe");
user.setUsername("user5");
user.setPasswordHash("1238");
user.setEmail("user5#domain.com");
System.out.println("Created user" + user);
User testUser = userService.saveUser(user);
System.out.println("Saved user" + testUser);
Assert.assertEquals("The user should be equal to saved user", user, testUser);
}
}
My test-context.xml used is as follows:
<context:annotation-config/>

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
<!-- User service implementation bean -->
<bean id="userMgmtService" class="users.service.impl.UserMgmtServiceImpl"/>
</beans>
The Repository implementation is a standard JPARepository:
public interface UserRepository extends JpaRepository<User, Long>
{
User findByUsername(String username);
}
And the service implementation only makes calls to the repository:
#Service("userMgmtService")
public class UserMgmtServiceImpl implements UserMgmtService
{
#Autowired
private UserRepository userRepository;
#Override
public User saveUser(User user)
{
User savedUser = userRepository.save(user);
return savedUser;
}
The problem is that when I execute the test, it passes, but no user is created in the database. I thought it might be because of the Rollback behavior so I set the defaultRollback=false in the User test. Here is some information provided by the transaction framework when set to DEBUG that might be relevant:

The logs show a testException=[null] but I have no idea why that would be.. I even tried to use the saveAndFlush() method provided by the JPARepository but doing so I get the error javax.persistence.TransactionRequiredException: no transaction is in progress
So if anyone has some idea of what I am doing wrong and can point me in the right direction I would very much appreciate the help.

Answer 1

After some careful reading of the logs, I found this warning:
WARN Ejb3Configuration:1309 - HHH000193: Overriding hibernate.transaction.factory_class is dangerous, this might break the EJB3 specification implementation
This was related to a property that I had set in the jpaPropertyMap bean in my tests-context.xml file:
<entry key="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory" />
It turns out that once I removed this line in the configuration file I could see hibernate performing an "insert" action and the user was actually created in the database. Since I am new to spring and all the technologies I used, I must have copied the configuration from somewhere without really analysing it. So, I am now able to run junit4 tests in a project using spring data, hibernate and bitronix as transaction manager.
