java - Jersey + Spring = @Transactional 不起作用

标签 java spring junit jersey transactional

您好，我启动了一个与 Spring 集成的 Jersey 应用程序。为了测试我的资源，我使用 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());
    }

问题是我的所有测试都在 @Before 方法中中断。为什么？因为用户 ID 为空。 让我们检查一下我的 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);
    }
...

有人可以帮助我让它工作吗？ 谢谢

编辑添加一些控制台日志:

编辑 6 我更改了这一行:

@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)

现在我遇到了另一个异常:

java.lang.AbstractMethodError: org.joda.time.contrib.hibernate.PersistentDateTime.nullSafeSet(Ljava/sql/PreparedStatement;Ljava/lang/Object;ILorg/hibernate/engine/spi/SessionImplementor;)V
    at org.hibernate.type.CustomType.nullSafeSet(CustomType.java:155)
    at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:2602)

最佳答案

聊天讨论摘要

  1. 将@Transactional添加到测试类
  2. 在@TransactionConfiguration中添加transactionManager

@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true) @事务性 //测试类

一些论坛建议使用Jadira 使用此注释

@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTimeWithZone")
