Запрос на спящий режим не возвращает правильные результаты

Question

Я разрабатываю веб-приложение с спящим и весенним периодом. Я использую аннотацию для любой конфигурации.

Моя проблема заключается в том, чтобы выбрать таблицу с двумя внешними ключами.

Объект, который содержит все есть:

@Entity 
@Table(name = "WAR_PLAYERS_ATTACKS") 
public class WarPlayerAttack implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "WAR_PLAYER") 
    private WarPlayer warPlayer; 

    @Id 
    @ManyToOne 
    @JoinColumn(name = "ATTACK") 
    private Attack attack; 

    @ManyToOne 
    @JoinColumn(name = "TYPE_ATTACK") 
    private TypeAttack typeAttackInWar; 

    public WarPlayerAttack() { } 

    // getters and setters 
} 

Entity warPlayer:

@Entity 
@Table(name = "WAR_PLAYERS") 
public class WarPlayer implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name = "ID", nullable = false) 
    private int id; 

    @ManyToOne 
    @JoinColumn(name = "WAR") 
    private War war; 

    @ManyToOne 
    @JoinColumn(name = "PLAYER") 
    private Player player; 

    @Column(name = "WAR_NUMBER") 
    private int warNumber; 

    @Column(name = "HAVE_KING") 
    private boolean haveKing; 

    @Column(name = "HAVE_QUEEN") 
    private boolean haveQueen; 

    @Column(name = "HAVE_POTIONS") 
    private boolean havePotions; 

    @OneToMany(mappedBy = "warPlayer", fetch = FetchType.EAGER) 
    private List<WarPlayerAttack> attacks; 

    public List<WarPlayerAttack> getAttacks() { 
     return attacks; 
    } 

    public void setAttacks(List<WarPlayerAttack> attacks) { 
     this.attacks = attacks; 
    } 

    private String comment; 

    public WarPlayer() {} 

Мой DAO

@Override 
    public List<WarPlayerAttack> findByIdEnemyAndIdWar(int idEnemy, int idWar) throws DaoException { 

     List<WarPlayerAttack> attackss = null; 
     List attacks; 

     try { 
      attackss = getSession() 
       .createQuery("from WarPlayerAttack wpa where wpa.attack.enemy.id in :idEnemy and wpa.attack.enemy.war.id in :idWar") 
       .setParameter("idEnemy", idEnemy) 
       .setParameter("idWar", idWar) 
       //.createSQLQuery("select * from WAR_PLAYERS_ATTACKS where ATTACK in (select ID from ATTACKS where ENEMY in (select ID from WAR_ENEMIES where ID = ? and WAR = ?))") 
       //.setParameter(0, idEnemy) 
       //.setParameter(1, idWar) 
       .list(); 
     } catch (Exception e) { 
      throw new DaoException(e.getMessage()); 
     } 

     return attackss; 
    } 

Моя проблема заключается в спящий режим не собирает warPlayer. Соберите только Attack и TypeAttack. Пример данных, собранных в формате JSON (атака появляется, но не warPlayer):

[ 
    {"attack":{"id":15,"enemy":{"id":10,"diffculty":0,"warNumber":2},"stars":1,"strategy":{"id":1,"value":"Air"},"timeRange":{"id":1,"value":"6H"}},"typeAttackInWar":{"id":3,"value":"Final 1"}}, 
    {"attack":{"id":16,"enemy":{"id":10,"diffculty":0,"warNumber":2},"stars":2,"strategy":{"id":2,"value":"Ground"},"timeRange":{"id":3,"value":"18H"}},"typeAttackInWar":{"id":4,"value":"Final 2"}} 
] 

Если я делать с SQL дао вернуть мне Object[] как [[1,1,1],[1,2,1]]

Столы для получения дополнительной информации:

CREATE TABLE WAR_ENEMIES (
    ID INT AUTO_INCREMENT NOT NULL, 
    WAR INT NOT NULL, 
    WAR_NUMBER INT(2) NOT NULL, 
    DIFFCULTY INT(1), 

    CONSTRAINT PK_ENEMY PRIMARY KEY (ID), 
    CONSTRAINT FK_ENEMY_WAR FOREIGN KEY (WAR) REFERENCES WARS(ID) 
); 

CREATE TABLE ATTACKS (
    ID INT AUTO_INCREMENT NOT NULL, 
    ENEMY INT, 
    STARS INT(1) DEFAULT 0,

    TIME_RANGE INT,

    WAR_NUMBER INT(2) NOT NULL, 
    HAVE_KING TINYINT(1) NOT NULL DEFAULT 1, 
    HAVE_QUEEN TINYINT(1) NOT NULL DEFAULT 1, 
    HAVE_POTIONS TINYINT(1) NOT NULL DEFAULT 1, 
    COMMENT VARCHAR(2500), 

    CONSTRAINT PK_PLAYER_IN_WAR PRIMARY KEY (ID), 
    CONSTRAINT FK_PLAYER_IN_WAR FOREIGN KEY (WAR) REFERENCES WARS(ID), 
    CONSTRAINT FK_PLAYER_IN_WAR_PLAYER FOREIGN KEY (PLAYER) REFERENCES PLAYERS(ID) 
); 
CREATE TABLE WAR_PLAYERS_ATTACKS (
    WAR_PLAYER INT NOT NULL, 
    ATTACK INT NOT NULL, 
    TYPE_ATTACK INT NOT NULL, 

    CONSTRAINT PK_WAR_PLAYER_ATTACK PRIMARY KEY (WAR_PLAYER, ATTACK), 
    CONSTRAINT FK_WAR_PLAYER_ATTACK_WAR_PLAYER 
     FOREIGN KEY (WAR_PLAYER) REFERENCES WAR_PLAYERS(ID), 
    CONSTRAINT FK_WAR_PLAYER_ATTACK_ATTACK 
     FOREIGN KEY (ATTACK) REFERENCES ATTACKS(ID), 
    CONSTRAINT FK_WAR_PLAYER_ATTACK_TYPE 
     FOREIGN KEY (TYPE_ATTACK) REFERENCES TYPE_ATTACK(ID) 

); 

Я не знаю, что я делаю неправильно. (У меня мало времени с спящим)

Заранее благодарен.

У меня была аналогичная проблема с использованием реализации EclipseLink, в которой я решил просто вызвать метод call. .Ize() в prder для инициализации ленивого набора. См. How to load lazy fetched items from Hibernate/JPA in my controller
