无法让@Rollback为我的Spring JPA集成测试工作

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/META-INF/catalog-spring.xml" })
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
public class TermTest
{
    @Autowired
    private CatalogService service;
    @Rollback(true)
    @Test
    public void testSimplePersist()
    {   
        Term term = new Term();
        term.setDescription("Description");
        term.setName("BirdSubject8");
        term.setIsEnabled("F");
        term.setIsSystem("F");
        term.setTermType("TERM");
        service.createTerm(term);
    }
}
