java - Spring @Transactional 方法不回滚

Question

我有问题要问 Spring、hibernate 和 testng。

我正在开发一个应用程序并尝试编写一个事务性单元测试。问题是，当我的业务方法被标记为“事务性”时，我如何回滚我的数据库操作？

代码:

@Test
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
@TransactionConfiguration(defaultRollback = true)
public class SampleTest extends
AbstractTransactionalTestNGSpringContextTests {


@Autowired
private AuthorDao authorDao; 

@BeforeTest
void createAppCtx() {
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
            "/applicationContext.xml");

}


@Test
void testStg() {

    Person person = new Author();
    person.setFirstName("Edward");
    person.setLastName("Kowalski");
    authorDao.createAuthor(person);
}

在我的 authorDao 中，我有以下方法:

@Repository
@Transactional
public class AuthorDao {

@PersistenceContext
private EntityManager entityManager;


public AuthorDao() {

}

public AuthorDao(EntityManager entityManager) {
    this.entityManager = entityManager;
}

public Author createAuthor(Person author) {
    entityManager.persist(author);
    return (Author) author;
}

如果需要应用上下文，我也可以附加它。
因此，正如您所见，业务方法是事务性的，因此调用后会进行提交。那么重点是如何避免在测试类中提交？是否可以？

非常感谢您的帮助。

编辑:应用上下文:

也将@Transactional 添加到测试方法，以便应用 TransactionConfiguration。
