«Нет CurrentSessionContext настроен», когда приложение пытается выполнить запрос в базе данных

Question

В моем текущем проекте загрузки Spring, когда я пытаюсь выполнить запрос в базе данных, используя этот метод из моего класса dao (это уникальный, который я использовал в этом этап развития):

public class Dao<E extends Model> { 

    @Autowired 
    private SessionFactory sessionFactory; 

    ... 

    @Transactional 
    public E findByField(String field, String value) { 
     return (E) sessionFactory.getCurrentSession().createQuery("from "+clazz.getSimpleName()+" where "+field+" = :data").setParameter("data", value).uniqueResult(); 
    } 
} 

Я получаю эту ошибку:

     ... 35 common frames omitted 

этот метод вызывается из этого класса обслуживания:

@Component 
public class AcessoService implements UserDetailsService { 

    @Autowired 
    private UsuarioDao usuario; 

    @Override 
    @Transactional 
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { 
     Usuario account = (Usuario) usuario.findByField("login", username); 

    if(account==null) 
     throw new UsernameNotFoundException("No such user: " + username); 
    else if (account.getRole().isEmpty()) 
     throw new UsernameNotFoundException("User " + username + " has no authorities"); 

    List<Permission> lista = new ArrayList<Permission>(); 
    int max = account.getRole().size(); 
    for(int i=0; i<max; i++) { 
     int max2 = account.getRole().get(i).getPermission().size(); 
     for(int j=0; j<max2; j++) 
      lista.add(account.getRole().get(i).getPermission().get(j)); 
    } 

    boolean accountIsEnabled = true; 
    boolean accountNonExpired = true; 
    boolean credentialsNonExpired = true; 
    boolean accountNonLocked = true; 

    return new User(account.getLogin(), account.getSenha(), accountIsEnabled, accountNonExpired, credentialsNonExpired, accountNonLocked, getAuthorities(lista)); 
    } 
} 

Это мой application.properties файл:

# jdbc.X 
spring.datasource.driverClassName=org.postgresql.Driver 
spring.datasource.url=jdbc:postgresql://localhost:5432/mystore?charSet=LATIN1 
spring.datasource.username=klebermo

и у меня есть этот класс конфигурации, чтобы установить SessionFactory боб:

@Configuration 
public class HibernateConfig { 
    @Bean 
    public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) { 
     HibernateJpaSessionFactoryBean factory = new HibernateJpaSessionFactoryBean(); 
     factory.setEntityManagerFactory(emf); 
     return factory; 
    } 
} 

каждый может увидеть то, что я здесь отсутствует?

Answer 1

Итак, после дополнительных поисков я наконец нашел решение этой проблемы. Я solvw это добавить этот метод в моем Dao класс:

public Session getSessionFactory() { 
    try { 
     return sessionFactory.getCurrentSession(); 
    } catch (Exception e) { 
     return sessionFactory.openSession(); 
    } 
} 

и изменение вызова:

sessionFactory.getCurrentSession() 

в методах этого:

getSessionFactory() 

UPDATE

другое решение, которое я нашел, это использование

@Autowired 
private EntityManagerFactory factory; 

и

public EntityManager getEntityManager() { 
    return factory.createEntityManager(); 
} 

в моем классе дао, и в каждом из способов, использовать что-то вроде этого:

@Transactional 
public void insert(E object) { 
    getEntityManager().persist(object); 
}
