Java 在Hibernate中，两个实体如何与第三个实体具有多对多单向关系？

使用部署在JBoss4上的现有工作Hibernate3代码，现在我尝试将其部署在Wildfly 10（Hibernate5）上。在部署时完成验证期间，将显示以下消息：

org.hibernate.persister.walking.spi.WalkingException: Association has already been visited: AssociationKey(table=pur_DemandDtl_DemandHeader, columns={DemandEventHeaderTRIk})

（我将在下面显示完整的堆栈）

首先，我将做一个总结： 共有3节课。在两个类中，有一个成员集被注释为ManyToMany，并且是单向的。这一组有三等兵

有3个表对应于3个类中的每一个。 此外，还有第四个表表示这两种关联。 第四个表有3列。每列对应一个表。 显然，在每一行中，与两个表关联的两列中的一列都有一个空值

我几乎没有使用Hibernate的经验，但看起来每个关系的定义与我所看到的所有示例中的定义完全相同。我脑子里唯一的问题是：1）我是否必须做其他事情，因为有两张桌子与第三张桌子有关系？2） 在同一个关联表中保留两个关联是否合法？3） 前两类的层次结构有问题吗

好的，现在我将展示一些代码。我将省略一些细节，如果需要的话，稍后将添加

前两类是PromotedTL和ReserveDtl。它们共享一个公共的超类PromoReserveDtl，并且每个都与第三类DemandEventHeaderTriggerRecord具有单向的多个关系

@MappedSuperclass
public abstract class PromoReserveDtl implements Serializable,Comparable<PromoReserveDtl>{

    private Integer promoReserveDtlIk;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
        @Column(name = "PromoReserveDtlIk")
    public Integer getPromoReserveDtlIk() {
        return promoReserveDtlIk;
    }
    protected Set<DemandEventHeaderTriggerRecord> demandEventHeaderTriggerRecord = new HashSet<DemandEventHeaderTriggerRecord>();
    public void setDemandEventHeaderTriggerRecord(Set<DemandEventHeaderTriggerRecord> demandEventHeaderTriggerRecord) {
        this.demandEventHeaderTriggerRecord = demandEventHeaderTriggerRecord;
    }
    // other stuff
}  

@Entity
@Table(name="pur_PromoDtl")
public class PromoDtl extends PromoReserveDtl implements Serializable{
    @ManyToMany(fetch = FetchType.EAGER,cascade = { CascadeType.ALL })
    @JoinTable(name="pur_DemandDtl_DemandHeader",
          joinColumns=@JoinColumn(name="PromoDtlIk"),
          inverseJoinColumns=@JoinColumn(name="DemandEventHeaderTRIk"))
    public Set<DemandEventHeaderTriggerRecord> getDemandEventHeaderTriggerRecord() {
        return demandEventHeaderTriggerRecord;
    }
    // other stuff
}

@Entity
@Table(name="pur_ReserveDtl")
public class ReserveDtl extends PromoReserveDtl implements Serializable {
    @ManyToMany(fetch = FetchType.EAGER,cascade = { CascadeType.ALL })
    @JoinTable(name="pur_DemandDtl_DemandHeader",
          joinColumns=@JoinColumn(name="ReserveDtlIk"),
          inverseJoinColumns=@JoinColumn(name="DemandEventHeaderTRIk"))
    public Set<DemandEventHeaderTriggerRecord> getDemandEventHeaderTriggerRecord() {
        return demandEventHeaderTriggerRecord;
    }
    // other stuff
}

@Entity
@Table(name="pur_DemandEventHeaderTriggerRecord")
public class DemandEventHeaderTriggerRecord  implements Serializable{
    private Integer demandEventHeaderTRIk;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "DemandEventHeaderTRIk")
    public Integer getDemandEventHeaderTRIk() {
        return demandEventHeaderTRIk;
    }
    public boolean equals(Object other) {
        //...
    }
    public int hashCode() {
        //...
    }
}
