Hibernate почему создает n запрос вместо 1?

Hy Я хочу загрузить все рабочие таблицы из таблицы JobSeeker с помощью одного запроса и с критериями, а вместо спящего режима вместо спящего 1 запроса написать n запрос для n JobSeeker, и у меня нет идеи, почему бы вам помочь. Это мой JobSeeker класс:Hibernate почему создает n запрос вместо 1?

@Entity 
@Table(name="JOB_SEEKER") 
public class JobSeeker extends BaseEntity{ 

@Column(name = "name", length = 128, nullable = false) 
@Expose 
private String name; 

@OneToOne 
@JoinColumn(name = "user_id") 
private User user; 

. 
. 
.

Это мой класс User:

@Entity 
@Table(name="USER_AUTH") 
public class User extends BaseEntity { 

@Column(name = "username", nullable = false, length = 64, unique = true) 
@Size(max=64) 
@Expose 
@NotEmpty 
private String username; 

@Column(name = "password", nullable = false, length = 64) 
@Size(min=6,max=64) 
private String password; 

@OneToOne(mappedBy = "user", cascade=CascadeType.ALL) 
private UserSettings userSettings; 


@OneToOne(mappedBy = "user", fetch = FetchType.LAZY, cascade=CascadeType.ALL) 
@Fetch(FetchMode.SELECT) 
private JobSeeker jobSeeker; 
. 
. 
.

И UserSettings класс:

@Entity 
@Table(name="USER_SETTINGS") 
public class UserSettings extends BaseEntity{ 

@OneToOne 
@JoinColumn(name = "user_id") 
@Expose 
private User user; 
. 
. 
.

И мой FindAll выбрать:

Session session = getCurrentSession(); 

Criteria criteria = session.createCriteria(JobSeeker.class, "jobSeeker") 
     .setFirstResult(dataTableFilter.iDisplayStart) 
     .setMaxResults(dataTableFilter.iDisplayLength); 
List<?> list = new ArrayList(); 
list = criteria.list();

И это делает это querys:

Я пытался поставить в JobSeeker класса @OneToOne (скачивает = FetchType.LAZY) с этой записью только один запрос, но, например, в findOne() не дает прокси-сеанса для пользователя, не загружал пользователя, и мне это нужно. В findAll мне нужен только JobSeeker без пользователя. Я бы написал select с hibernate.query, но мне нужно сделать с критериями. Кто-нибудь может мне помочь?

UPDATE: Общий класс:

public abstract class AbstractHibernateDao<T extends BaseEntity, PK extends Serializable> implements IOperations<T, PK> { 

    private Class<T> clazz; 
    private Class<PK> pkClazz; 

    @Autowired 
    private SessionFactory sessionFactory; 


    protected final void setClazz(final Class<T> clazzToSet, final Class<PK> plClazzToSet) { 
     clazz = Preconditions.checkNotNull(clazzToSet); 
     pkClazz = Preconditions.checkNotNull(plClazzToSet); 
    } 

    @Override 
    public final T findOne(final PK id) { 
     return (T) getCurrentSession().get(clazz, id); 
    }

UPDATE Если fetchType ленивым идет хорошо на FindAll пишет только один запрос

@OneToOne(fetch = FetchType.LAZY, optional = false) 
@JoinColumn(name = "user_id") 
private User user;

но дает эту ошибку на jobSeekerService.findOne (идентификатор):

yo should google о n + 1 проблемах в спящем режиме и каждом круге. Есть способы настроить его. –

Это первое, что я делаю, но у меня не было решения для моей проблемы, вот почему я пришел сюда и спросил его – FAndrew

Просто замените конкретный фрагмент кода следующим кодом, и все готово.

@OneToOne(mappedBy = "user", fetch = FetchType.LAZY, optional = false, cascade=CascadeType.ALL) 
@Fetch(FetchMode.JOIN) 
private JobSeeker jobSeeker;

Престол, я просто изменил FetchMode.JOIN вместо FetchMode.SELECT.

С Hibernate Документов

SELECT: используйте избранный для каждого отдельного объекта, сбора, или присоединиться к нагрузке

Для получения более подробной информации, пожалуйста, обращайтесь: Hibernate Docs.

UPDATE: По умолчанию поведение в Hibernate, как это для извлечения стратегии, которая также играет роль здесь,

OneToMany: LAZY 
ManyToOne: EAGER 
ManyToMany: LAZY 
OneToOne: EAGER

Для преодоления этого вам просто нужно обновить отображение OneToOne в JobSeaker классе, как это,

@OneToOne(fetch = FetchType.LAZY, optional = false) 
@JoinColumn(name = "user_id") 
private User user;

Refer: Use of Optional flag.

ОБНОВЛЕНИЕ: Теперь у нас отключено поведение по умолчанию для активной загрузки спящего режима. Поэтому нам нужно вызвать спящий режим для загрузки данных, используя такой запрос соединения:

Session session = getCurrentSession(); 

Criteria criteria = session.createCriteria(JobSeeker.class, "jobSeeker") 
     .createAlias("jobSeeker.user","user") //default inner join 
     .setFirstResult(dataTableFilter.iDisplayStart) 
     .setMaxResults(dataTableFilter.iDisplayLength); 
List<?> list = new ArrayList(); 
list = criteria.list();

Я изменил и дал те же запросы. – FAndrew

, какую версию Hibernate вы используете? –

4.3.6.Final - version – FAndrew

Hibernate почему создает n запрос вместо 1?
