Я использую Spring с Hibernate и всегда получаю NPE для объекта sessionFactory.
Мой файл конфигурации:
@Configuration
public class HibernateConfiguration {
@Bean
public AnnotationSessionFactoryBean sessionFactory() {
Properties props = new Properties();
props.put("hibernate.dialect", MySQL5InnoDBDialect.class.getName());
props.put("hibernate.format_sql", "true");
props.put("hibernate.connection.driver_class", "com.mysql.jdbc.Driver");
props.put("hibernate.connection.password", "xxx");
props.put("hibernate.connection.url", "jdbc:mysql://localhost/Market");
props.put("hibernate.connection.username", "philipp");
AnnotationSessionFactoryBean bean = new AnnotationSessionFactoryBean();
bean.setAnnotatedClasses(new Class[] { xxx.class, xxx.class, xxx.class });
bean.setHibernateProperties(props);
bean.setSchemaUpdate(true);
return bean;
}
@Bean
public HibernateTransactionManager transactionManager() {
return new HibernateTransactionManager(sessionFactory().getObject());
}
@Bean
public PersistenceExceptionTranslationPostProcessor persistenceExceptionTranslationPostProcessor() {
return new PersistenceExceptionTranslationPostProcessor();
}
}
Мой класс DAOImpl:
@Repository("xxx")
public class xxxDAOImpl implements xxxDAO {
private SessionFactory sessionFactory;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
private Session currentSession() {
return sessionFactory.getCurrentSession();
}
...
Прецедент:
@ContextConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
public class TestxxxDAOImpl {
@Test
@Transactional
public void testInsertxxx() throws Exception {
xxxDAO xxxDAO = new xxxDAOImpl();
xyz xyz = new xyz();
xxxDAO.insert(xyz);
assertNotNull(xyz.getId());
}
}

I get always an NPE from the currentSession when the test calls the insert method.
public void insert(xxx xxx) {
currentSession().save(xxx);
}
private Session currentSession() {
return sessionFactory.getCurrentSession();
}
