我正在尝试设置基本的 JPA 插入测试。但数据库中没有保存任何内容。
数据库是Postgresql。 Hibernate 用作持久性提供者。
提前谢谢了。
@Entity
public class Currency {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
protected Integer id;
@Column
private String code;
@Column
private String name;
...
}
CRUD 类:
@Repository
@Scope(BeanDefinition.SCOPE_PROTOTYPE)
@Transactional(propagation = Propagation.REQUIRED)
public class CRUDServiceBean implements CRUDService {
@PersistenceContext(type = PersistenceContextType.EXTENDED)
private EntityManager entityManager;
public EntityManager getEntityManager() {
return entityManager;
}
public <T extends BaseEntity> T persistAndCommit(T t) {
entityManager.persist(t);
entityManager.refresh(t);
entityManager.getTransaction().commit();
return t;
}
...
...
}
所有测试的基类:
@RunWith(SpringJUnit4ClassRunner.class)
@Configurable(autowire = Autowire.BY_NAME)
@ContextConfiguration(locations = { "classpath:context-test.xml" })
public class BaseTest {
}
测试类:
public class CurrencyCreateTest extends BaseTest {
@Autowired
CRUDService crudService;
@Test
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void createCurrency() throws Exception {
Currency currency = new Currency();
currency.setCode("EUR");
currency.setName("Euro");
currency = crudService.persistAndCommit(currency);
}
}

如果您的测试成功通过并且没有收到任何异常,那么请使用@TransactionConfiguration(defaultRollback=false)每个测试类或使用@回滚(假)每个测试方法。
事务测试将在 Spring 测试上下文中默认回滚。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={
"test-context.xml"})
@TransactionConfiguration(defaultRollback=false)
@Transactional
public class SampleCrudTest {
@Autowired
private SampleCrud sampleCrud;
@Before
public void onSetUpInTransaction() throws Exception {
//Populate Test Data
}
@Test
public void registerSample() {
Sample sample = new Sample("foo");
sampleCrud.save(sample);
assertNotNull(sample.getId());
}
}
