我正在尝试测试将实体类添加到数据库中。但目前我只能做一次(((第二次启动测试,它失败了(((另外我注意到测试完成后数据没有被清除(((所以下一个测试只是崩溃,因为之前的数据仍然存在。代码和消息跟踪如下:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:application-context-test.xml"})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionalTestExecutionListener.class,
DbUnitTestExecutionListener.class })
@Transactional
public class HibernateAddingToBase {
@Autowired
SessionFactory sessionfactory;
Session session;
@Autowired
DataSource dataSource;
@Before
public void setUp() throws MalformedURLException, SQLException, DatabaseUnitException {
session = sessionfactory.getCurrentSession();
}
@Test
@Rollback(false)
@DatabaseSetup(value = "classpath:sampleData.xml")
@ExpectedDatabase(
value = "classpath:ExpectedAddedCategories.xml",
assertionMode = DatabaseAssertionMode.NON_STRICT
)
@DirtiesContext
public void testAddCategories() {
Category cat = new Category("sport");
Category cat2 = new Category("art");
Category cat3 = new Category("video");
session.persist(cat);
session.persist(cat2);
session.persist(cat3);
}
例外:

我尝试使用所有建议的 inet 解决方案(@DirtiesContext、空数据集文件等)清理数据库 - 它们在这里不起作用(((所以我的任务是每次启动它时都让这个测试工作。有什么想法吗?
