Question

我目前正在尝试在我的项目中使用Hibernate Envers，但是我遇到了以下异常。我认为这是因为MedicalSummaryId不包含数据并扩展了映射的超类，但我看不出如何解决它。

我正在使用Hibernate 4.3.8.Final。

例外：

MedicalHistory.java

@Entity
@Audited
public class MedicalHistory extends BaseEntity {
    @EmbeddedId MedicalHistoryId medicalHistoryId = new MedicalHistoryId();
    @NotNull String description;
}

MedicalHistoryId.java

@Embeddable
public class MedicalHistoryId implements Serializable {
    @NotNull public MedicalSummaryId medicalSummaryId;
    @NotNull public long id = 0;
}

MedicalSummaryId.java

@Embeddable
public class MedicalSummaryId extends AggregateRootId{
     // no data
}

AggregateRoot.id

@Embeddable
@MappedSuperclass
public class AggregateRootId implements Serializable {
    protected Integer id;
}

感谢您的帮助。

问题似乎来自复合键，因此，我找到了一个不令人满意的解决方法，而不是使用复合键，如果我使用一个简单的键就可以了。
