@Embeddable クラスを結合クラスの代表として使用して、エンティティをマッピングして多対多の結合テーブルを実現する際に問題が発生しています。基本的にここに私が達成しようとしているものがあります:
Java Hibernate Persistence book に記載されているチュートリアルに従いましたが、これらのメソッドからまだエラーが発生しています。

そのため、これらのテーブルを @Embeddable アノテーションと結合して、休止状態がそれをエンティティにマップできるようにします。しかし、エラー メッセージでわかるように、まったくマッピングされていません。
IncidentCategoryJoin.java:
@Embeddable
public class IncidentCategoryJoin implements Serializable {
@Parent // Optional back-pointer
private IncidentEntity incident;
@ManyToOne
@JoinColumn(name="category_id",
insertable = false,
updatable = false)
private CategoryEntity category;
@ManyToOne
@JoinColumn(name="categorytype_id",
insertable = false,
updatable = false)
private CategoryTypeEntity categoryType;
public IncidentCategoryJoin() {}
public IncidentCategoryJoin(
IncidentEntity incident,
CategoryEntity category,
CategoryTypeEntity categoryType) {
// Set fields
this.incident = incident;
this.category = category;
this.categoryType = categoryType;
// Guarantee referential integrity
incident.getIncidentCategoryJoins().add(this);
category.getIncidentCategoryJoins().add(this);
}
public IncidentEntity getIncident() {
return incident;
}
public void setIncident(IncidentEntity incident) {
this.incident = incident;
}
public CategoryEntity getCategory() {
return category;
}
public void setCategory(CategoryEntity category) {

}
public boolean equals(Object o) {
if (o != null && o instanceof IncidentCategoryJoin) {

return this.category.equals(that.getCategory()) &&
this.incident.equals(that.getIncident()) &&
this.categoryType.equals(that.getCategoryType());
} else {
return false;
}
}
public int hashCode() {
return category.getId() + incident.getId() + categoryType.getId();
}
}

なぜこれが私にとってうまくいかないのか、誰にもアイデアがありますか?? 公式の Java Hibernate Persistence book からこの方法に従っていることを心に留めておいてください。したがって、理論的には問題なく機能するはずです。SpringまたはHibernateのバグの可能性を検討しています。とにかく、ここで得られる助けに感謝します。
