我正在使用Spring 3.2.1.RELEASE，Hibernate 4.1.9.FINAL作为jpa提供程序，spring数据库1.2.0.RELEASE用于存储库和bitronix 2.1.3作为事务管理器启动项目。我是所有这些技术的新手，所以如果我错过了一些重点，我很抱歉。
我正在运行一个简单的单元测试来在数据库中创建一个User对象：
@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);
}
}
我使用的test-context.xml如下：
<context:annotation-config/>

</beans>
Repository实现是标准的JPARepository：
public interface UserRepository extends JpaRepository<User, Long>
{
User findByUsername(String username);
}
服务实现只调用存储库：
@Service("userMgmtService")
public class UserMgmtServiceImpl implements UserMgmtService
{
@Autowired
private UserRepository userRepository;
@Override
public User saveUser(User user)
{
User savedUser = userRepository.save(user);
return savedUser;
}
问题在于，当我执行测试时，它会通过，但数据库中没有创建用户。我认为这可能是因为Rollback行为所以我在User测试中设置了defaultRollback = false。以下是设置为DEBUG时可能相关的事务框架提供的一些信息：

日志显示testException = [null]但我不知道为什么会这样......我甚至尝试使用JPARepository提供的saveAndFlush（）方法但是这样做我得到了错误javax.persistence.TransactionRequiredException: no transaction is in progress
所以如果有人知道我做错了什么并且可以指出我正确的方向，我会非常感谢你的帮助。
答案 0 :(得分：1)
仔细阅读日志后，我发现了这个警告：
WARN Ejb3Configuration:1309 - HHH000193: Overriding hibernate.transaction.factory_class is dangerous, this might break the EJB3 specification implementation
这与我在tests-context.xml文件中的jpaPropertyMap bean中设置的属性有关：
<entry key="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory" />
事实证明，一旦我在配置文件中删除了这一行，我就可以看到hibernate执行“插入”操作，并且实际上是在数据库中创建了用户。由于我是Spring和我使用的所有技术的新手，我必须从某个地方复制配置而不进行真正的分析。所以，我现在能够使用spring数据，hibernate和bitronix作为事务管理器在项目中运行junit4测试。
