Hibernate上关系复合主键的问题

Question

我有这个图

我如何在实体 EscalaDetalhes 和 DefinicaoEscala 的 Hibernate 上创建关系，因为在 DefiniciaoEscala 实体上，有一个由 idDetalhe（外部与（EscalaDetalhes））和 idTurma（外部与（Turma））形成的复合主键。

我已经完成了如下课程：

@Embeddable

public class DefinicaoEscalaPK implements Serializable {

    @Column(name="myColumn")

    private Integer idTurma;

    @Column(name="myColumn2")

    private Integer idEscalaDia;

    //GETTERS , SETTERS , HASH AND EQUALS

}

@Entity

public class DefinicaoEscala implements Serializable {

    @EmbeddedId

    private DefinicaoEscalaPK id;

    @ManyToOne()

    @JoinColumn(name = "idTurno")

    private TurnoBean turno;

    //GETTERS , SETTERS , HASH AND EQUALS

}

@Entity

@Table(name ="table")

public class EscalaDetalhes{

    @id

    private Integer idDetalhe;

    @ManyToOne()

    @JoinColumn(name="mybdColumn")

    private EscalaBean escala;

    @Column(name="myColumn") 

    private Calendar dia;

    //MY QUESTION IS HERE , HOW WOULD I DESCRIBE THE RELATION HERE?  

    private List<DefinicaoEscala> escalaDiaDetalhes;

    //GETTERS , SETTERS , HASH AND EQUALS

}

我的问题在这里，我如何描述这种关系？

private List<DefinicaoEscala> escalaDiaDetalhes;
