No Session found for current thread
I'm new in spring (spring 3.1.2, hibernate 4, mysql 5.1).
I'm trying to test a simple service by using java configuration:
HTML Code:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig .class })
public class UserServiceTest {
@Autowired
private UserService userService;
@Test
public void testUserService() {
List<User> user = userService.listUsers();
assertEquals(2, user.size());
}
}
But this error is thrown ... I've read several posts with the same error but I didn't find the solution... If someone have any idea :), it would be great.
HTML Code:

The java configuration :
HTML Code:
@Configuration
@ComponentScan(basePackages = {"com.my.xxx.dao","com.my.xxx.service"})
public class MyConfig {
private static final Logger logger = LoggerFactory.getLogger(MyConfig.class);
@Bean
public SessionFactory sessionFactory() {

return mySessionFactory;
}
@Bean

@Bean

@Bean

My service :
HTML Code:
@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public void addUser(User user) {
userDao.addUser(user);
}
@Override
public List<User> listUsers() {
return userDao.listUsers();
}
@Override
public void removeUser(User user) {
// TODO Auto-generated method stub
}
}
My DAO :
HTML Code:
@Repository
@Transactional
public class UserDaoImpl implements UserDao {
@Autowired
private SessionFactory sessionFactory;
@Override
public void addUser(User user) {
// TODO Auto-generated method stub
}
@SuppressWarnings("unchecked")
@Override
public List<User> listUsers() {
List<User> users = (List<User>)sessionFactory.getCurrentSession().createSQLQuery("select * from Users").list();
return (List<User>) sessionFactory.getCurrentSession().createQuery("from User")
.list();
}
@Override
public void removeUser(User user) {
// TODO Auto-generated method stub
}
}
My entity :
HTML Code:
@Entity
@Table(name = "Users")
public class User implements Serializable {
@Id
@Column(name = "u_id")
@GeneratedValue
private Integer id;
@Column(name="u_lastname")
String name;
@Column(name="u_firstname")
String firstname;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
}
