我有一个Spring-JUnit测试,其中的安装方法使用JPA实体来设置测试数据。在测试本身中,遗留代码使用JDBC-Templates来查询插入的测试数据。当遗留代码发出查询时,对jdbcTemplate.query(...)的调用将挂起。
我的单元测试看起来像这样:
@TransactionConfiguration(defaultRollback = false)
@ContextConfiguration(locations = { "/testContext.xml" })
@Transactional
public class MyTest {
@PersistenceContext(unitName = "someUnit")
private EntityManager entityManager;
@Test
public void test() {
// here some legacy Code is called that uses JDBC Templates to query
// the inserted test data. The legacy code hangs upon jdbcTemplate.query(...)
}
@Before
public void before() {
this.entityManager.persist(new Entity1(...));
this.entityManager.persist(new Entity2(...));
}
}
我的问题是:为什么enitymanager在退出before()方法时没有提交?或者它是否提交并立即启动仍然引用存储实体的新事务?我还试着没有junit注释@Before注释并手动调用before()方法。但是这给出了相同的结果。
非常感谢任何建议。

测试类
@ContextConfiguration(locations = { "/testContext.xml" })
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = false)
@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
public class MyTest extends AbstractTransactionalJUnit4SpringContextTests{
@PersistenceContext(unitName = "someUnit")
private EntityManager entityManager;
@Autowired
private BeforeService beforeService;
@Test
public void test() {
beforeService.before();
// here some legacy Code is called that uses JDBC Templates to query
// the inserted test data. The legacy code hangs upon jdbcTemplate.query(...)
}
}
服务前
public class BeforeService {
private EntityManager entityManager;
@PersistenceContext
public void setEntityManager(final EntityManager entityManager) {
this.entityManager = entityManager;
}
@Transactional(propagation=Propagation.REQUIRES_NEW)
public void before() {
entityManager.persist(new Entity1(...));
entityManager.persist(new Entity2(...));
}
}
我希望我已经向你提供了有关你问题的所有答案。
