Spring Test Transaction回滚问题

我有一个问题,理解@Transactional和@TransactionConfiguration(defaultRollback = true)注释。

我有一个将userAccount插入数据库的测试代码,然后应该插入另一个具有相同名称的帐户,这会导致DataIntegrityViolationException,因为AccountName被标记为Unique。如果在TestClass级别没有分析@Transactional和@TransactionConfiguration(defaultRollback = true),这样可以正常工作。但是如果启用了Rollback,我就不会得到Exception,因为即使在相同的方法中,数据也不会插入到数据库中。如果我在插入第一个帐户后设置了断点,则数据库仍为空。

这是我的代码:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/spring/applicationContext.xml"})
@Transactional
@TransactionConfiguration(defaultRollback = true)
public class DaoTests {

    @Autowired
    private Repository repo;
    @Autowired
    private AccountService userService;

    @Before
    public void orgInstAccount() {
        Organization o = new Organization();
        o.setName("Organisation 1");
        repo.saveEntity(o);

        Institution i1 = new Institution();
        i1.setName("xyz");
        i1.setOwningOrganization(o);
        repo.saveEntity(i1);

    }

    @Test(expected = DataIntegrityViolationException.class)
    public void saveUserFail() {

        Account user = new Account();
        user.setAccountname("chz");
        user.setPassword(userService.calcMD5Hash("123"));
        user.setOwningInstitution(repo.getInstitutionByName("xyz"));
        repo.saveEntity(user);
        Assert.assertNotNull(repo.getAccountByName("chz"));


        Account userNew = new Account();
        userNew.setAccountname("chz");
        userNew.setPassword(userService.calcMD5Hash("123"));
        userNew.setOwningInstitution(repo.getInstitutionByName("xyz"));
        repo.saveEntity(userNew);
        //Here the Exception should be thrown but everything works fine.

    }

}

存储库实现是:

@Repository
@Transactional
@SuppressWarnings("unchecked")
public class RepositoryHibernateImpl implements Repository {

    @Autowired
    private SessionFactory factory;

    @Override
    public void saveEntity(Entity hce) {
        factory.getCurrentSession().save(hce);
    }
}

问题可能是因为Repository和TestClass标有@Transactional?

先谢谢你。

调用flush(),它会尝试立即调用sql而不是将其推迟到事务边界

factory.getCurrentSession().flush()
