Я использую @Bean и @Annotation в своих классах так:
@Transactional
@Configuration
public class UserDAO {
@Bean
public UserDAO userDAO()
{
return new UserDAO();
}
private HibernateTemplate hibernateTemplate;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}
public void Save(User s){
this.hibernateTemplate.save(s);
}
}
Вот мой spring-servlet.xml. Обратите внимание, что я не пишу никаких бинов типа 'userDAO':

Все работало нормально, я могу сохранить пользователя в моем веб-приложении. Теперь я хочу сделать простой тест, подобный этому:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration (locations = {"classpath:**/spring-servlet.xml"})
@DependsOn("UserDAO")
@Transactional
@Configuration
public class UserDAOTest extends AbstractTransactionalDataSourceSpringContextTests {
@Autowired
private UserDAO userDAO;
@Autowired
private SessionFactory sessionFactory;
public UserDAO getUserDAO() {
return userDAO;
}
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Test
public void testSave() {
User spr = new User();
spr.setKzId(0);
spr.setOpis("User test");
spr.setPlan("Plan test");
spr.setPolrocze(1);
spr.setPrognoza1("test1");
spr.setPrognoza2("test2");
spr.setRok(2000);
userDAO.Save(spr);
User spr2 = userDAO.GetUserById(spr.getId());
Assert.assertEquals("User test", spr2.getOpis());
}
}
Но после запуска этого теста я получил ошибку:
