休眠嵌入式密鑰與另一個實體和字段

在我的情況下，我有實體'遊戲'和'GameCodeColor'。遊戲的PK是一個int ID。 GameCodeColor的PK應該是一個'遊戲'和一個整數。但在行：

sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();

我不斷收到：

"Unable to find properties (Game, GameCodeColorIndex) in entity annotated with @IdClass:h.GameCodeColor"

這裏是代碼我到目前爲止： GameCodeColorPK

package h; 

import javax.persistence.*; 
import java.io.*; 

@Embeddable 
public class GameCodeColorPK implements Serializable { 

    @OneToOne 
    @JoinColumn(name = "gc_g_Id", referencedColumnName = "g_Id") 
    protected Game Game; 
    @Basic 
    @Column(name = "gc_Index") 
    protected int GameCodeColorIndex; 

    public GameCodeColorPK() { 
    } 

    public GameCodeColorPK(Game Game, int GameCodeColorIndex) { 
     this.Game = Game; 
     this.GameCodeColorIndex = GameCodeColorIndex; 
    } 

    @Override 
    public boolean equals(Object obj) { 
     if (obj == null) { 
      return false; 
     } 
     if (getClass() != obj.getClass()) { 
      return false; 
     } 
     final GameCodeColorPK other = (GameCodeColorPK) obj; 
     if (this.Game != other.Game && (this.Game == null || !this.Game.equals(other.Game))) { 
      return false; 
     } 
     if (this.GameCodeColorIndex != other.GameCodeColorIndex) { 
      return false; 
     } 
     return true; 
    } 

    @Override 
    public int hashCode() { 
     int hash = 7; 
     hash = 71 * hash + (this.Game != null ? this.Game.hashCode() : 0); 
     hash = 71 * hash + this.GameCodeColorIndex; 
     return hash; 
    } 
}

GameCodeColor

package h; 

import javax.persistence.*; 
import java.io.*; 

@Entity 
@Table(name = "GameCodeColors") 
@IdClass(GameCodeColorPK.class) 
public class GameCodeColor implements Serializable { 

    @EmbeddedId 
    private GameCodeColorPK GameCodeColorPK; 

    public GameCodeColor() { 
    } 

    public h.GameCodeColorPK getGameCodeColorPK() { 
     return GameCodeColorPK; 
    } 

    public void setGameCodeColorPK(h.GameCodeColorPK GameCodeColorPK) { 
     this.GameCodeColorPK = GameCodeColorPK; 
    } 
    @Basic 
    @Column(name = "gcode_gc_Index") 
    private int GameColorIndex; 

    public int getGameColorIndex() { 
     return GameColorIndex; 
    } 

    public void setGameColorIndex(int GameColorIndex) { 
     this.GameColorIndex = GameColorIndex; 
    } 

    public GameCodeColor(h.GameCodeColorPK GameCodeColorPK, int GameColorIndex) { 
     this.GameCodeColorPK = GameCodeColorPK; 
     this.GameColorIndex = GameColorIndex; 
    } 
}

問題。

顯然，我不應該同時使用@IdClass和@EmbeddedId。

通常的屬性應爲小寫：

protected Game game

而且你缺少解決了getter和遊戲的制定者和gameCodeColorIndex

那麼你是對的，但它並沒有解決它。同樣的問題。 – TTT 2012-03-30 12:21:46
