我正在使用 Spring 3.2.1.RELEASE、Hibernate 4.1.9.FINAL 作为 jpa 提供程序、spring data 1.2.0.RELEASE 用于存储库和 bitronix 2.1.3 作为事务管理器来启动一个项目。我对所有这些技术都是新手，所以如果我遗漏了一些重要的观点，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用户对象：

@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/>

    class="bitronix.tm.TransactionManagerServices">

    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />


<!-- User service implementation bean -->
  <bean id="userMgmtService" class="users.service.impl.UserMgmtServiceImpl"/> 

</beans>

Repository 实现是一个标准的 JPARepository：

public interface UserRepository extends JpaRepository<User, Long>
{
User findByUsername(String username);
}

并且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;
}

问题是当我执行测试时，它通过了，但没有在数据库中创建用户。我认为这可能是因为回滚行为，所以我在用户测试中设置了 defaultRollback=false。以下是事务框架在设置为 DEBUG 时提供的一些可能相关的信息：

日志显示 testException=[null] 但我不知道为什么会这样。我什至尝试使用 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我做错了，可以为我指明正确的方向，我将非常感谢您的帮助。

在仔细阅读日志后，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，并且用户实际上是在数据库中创建的。由于我是 spring 和我使用的所有技术的新手，我一定是从某个地方复制了配置而没有真正分析它。因此，我现在可以在项目中使用 spring data、hibernate 和 bitronix 作为事务管理器来运行 junit4 测试。
