您好，我启动了将Jersey与spring集成的应用程序。为了测试我的资源，我正在使用spring-test，如下所示：
@ContextConfiguration(locations = { "classpath*:testApplicationContext.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
@TransactionConfiguration(defaultRollback = false) //just to check if txmanager was working
public class UserDAOTest {
@Autowired
private UserDAO dao;
@Autowired
private AuthorizationVerifyer verifyer;
@Before
public void init() {
User user = new User(null, "name", "email", "pass", DateTime.now(), true);
User savedUser = dao.save(user);
assertNotNull(savedUser);
assertNotNull(savedUser.getId());
}
问题是我所有的测试都在@Before方法中中断。为什么？因为用户ID为空。
让我们回顾一下我的testApplicationContext.xml：

我的UserDAO类：
@Component
public class UserDAO {
private GenericDAO<Long, User> dao;
@PersistenceContext
private EntityManager manager;
@Transactional
User save(User user) {
return dao.save(user);
}
...
有人可以帮我解决这个问题吗？
谢谢

编辑6我更改了这一行：
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
现在，我又遇到了一个例外：

最佳答案
聊天讨论摘要
将@Transactional添加到测试类
在@TransactionConfiguration中添加transactionManager
@TransactionConfiguration（transactionManager =“ transactionManager”，defaultRollback = true）
@交易
//测试类
一些论坛建议使用Jadira
带有此注释
@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTimeWithZone")
