Rollback error in using Spring DBUnit, Spring Data and embedded H2 database

I've been stuck in a curios error.

I have a small DBUnit Test:

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration("classpath:spring/testApplicationContext.xml") 
@Category(Integrationtest.class)
@TestExecutionListeners({ 
    DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class,
    TransactionDbUnitTestExecutionListener.class
    })
@DatabaseSetup("classpath:db/wbSchluesselwertData.xml")
public class KontaktrolleRepositoryIntegrationTest {


    @Autowired
    KontaktrolleRepository kontaktrolleRepository;

    @Autowired
    KontaktBeteiligterRepository kontaktBeteiligterRepository;

    @Autowired
    WbSchluesselwertRepository wbSchluesselwertRepository;
........
........
    @Test
    @Transactional
    public void that_Kontaktrolle_Is_Inserted_Into_DB() throws Exception {

        WbSchluesselwert wbRolle1 = wbSchluesselwertRepository.findOne(new Long(11)); 

        KontaktBeteiligter b1 = new KontaktBeteiligterBuilderAws(erzeugtAm).withName("Posteingang")
                .withStandort("Cologne").withOrganization("private").build();


        KontaktBeteiligter result = kontaktBeteiligterRepository.save(b1);

        Kontaktrolle r1 = new KontaktrolleBuilder(erzeugtAm).withBeteiligter(result).withRollenartId(wbRolle1).build();

        Kontaktrolle resultRolle = kontaktrolleRepository.save(r1);

        assertNotNull(resultRolle);
        assertNotNull(resultRolle.getKontaktrolleId());
        assertThat(resultRolle.getKontaktrolleId(), greaterThan(0L));

    }

Nothing more. First I want to search an entry which is prefilled by DBUnit (wbSchluesselwertData.xml). And after that I want to save two entries via Spring Data CrudRepository within a embedded H2 memory Database.

This datasource is wrapped by an HibernateJpaVendorAdapter and the adapter itself in a LocalContainerEntityManagerFactoryBean:

<bean id="emf"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
    <property name="packagesToScan" value="de.axa.chronik.persistence.domain" />
</bean>

If I run the unit test above I got the following error:

21:21:55,808 DEBUG JpaTransactionManager:594 - Closing JPA EntityManager [org.hibernate.ejb.EntityManagerImpl@f6b9e9] after transaction
21:21:55,808 DEBUG EntityManagerFactoryUtils:338 - Closing JPA EntityManager

    at org.h2.message.DbException.getJdbcSQLException(DbException.java:332)

So the subsequent attempt to persist the entity fails because the connection has been closed. Are there exsisting effects between hibernate persist and the use ob Spring DBUnit which I disregard?

Any help is appreciated. Many thanks in advance.

Try to change your TestExecutionListeners. This setup worked for me:

@TestExecutionListeners({
    DependencyInjectionTestExecutionListener.class,
    DbUnitTestExecutionListener.class,
    TransactionalTestExecutionListener.class
})

There's no org.h2.jdbc.JdbcSQLException: The object is already closed [90007-175] error anymore, and my tests are executed inside a transaction now. BUT changes made in DbUnit's @DatabaseSetup are not rolled back when transaction ends (i.e. after each test case).
