Java Hibernate-子类必须在它之后绑定'；母亲班

将hibernate从版本4.3.7.Final升级到版本5.3.18.Final后，我得到以下错误

@Entity
@Audited
@AuditPermission(Permission.VIEW_INDIVIDUAL)
public class Individual implements ITemporalEntity {

    @Id
    @Column(name = "Individual_id")
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "Individual_generator")
    @SequenceGenerator(name = "Individual_generator", initialValue = 1, allocationSize = 1, sequenceName = "Individual_id_seq")
    private Long id;
    @Embedded
    private TemporalEntity temporal = new TemporalEntity();
    @Override
    public DateTime getCreateDate() {
     return temporal.getCreateDate();
    }

    @Override
    public void setCreateDate(DateTime createDate) {
     temporal.setCreateDate(createDate);

    }
    .......
    ...

   }

临时性类

@Embeddable
public class TemporalEntity {

@Column(updatable = false)
private DateTime createDate;

@Column
private DateTime lastModifiedDate;

@ManyToOne
@JoinColumn(name = "created_by_id", updatable = false)
private AdminUser createdBy;

@ManyToOne
@JoinColumn(name = "last_modified_by_id")
private AdminUser lastModifiedBy;

@Column(nullable = false, columnDefinition = "boolean not null default false")
private boolean deleted = false;

public DateTime getCreateDate() {
    return createDate;
}

public void setCreateDate(DateTime createDate) {
    if (createDate == null) {
        //ignore attempts to clear this field
        return;
        //throw new IllegalStateException("Null create date not allowed");
    }
    this.createDate = createDate;
}

public DateTime getLastModifiedDate() {
    return lastModifiedDate;
}

public void setLastModifiedDate(DateTime lastModifiedDate) {
    if (lastModifiedDate == null) {
        //ignore attempts to clear this field
        return;
        //throw new IllegalStateException("Null last modified date not allowed");
    }
    this.lastModifiedDate = lastModifiedDate;
}

public AdminUser getCreatedBy() {
    return createdBy;
}

public void setCreatedBy(AdminUser createdBy) {
    if (createdBy == null) {
        //ignore attempts to clear this field
        return;
        //throw new IllegalStateException("Null created by not allowed");
    }
    this.createdBy = createdBy;
}

public AdminUser getLastModifiedBy() {
    return lastModifiedBy;
}

public void setLastModifiedBy(AdminUser lastModifiedBy) {
    if (lastModifiedBy == null) {
        //ignore attempts to clear this field
        return;
        //throw new IllegalStateException("Null lastModifiedBy not allowed");
    }
        this.lastModifiedBy = lastModifiedBy;
    }

    public boolean isDeleted() {
        return deleted;
    }

    public void setDeleted(boolean deleted) {
        this.deleted = deleted;
    }

}

项目临时性接口

public interface ITemporalEntity {

    public DateTime getCreateDate();

    public void setCreateDate(DateTime createDate);

    public DateTime getLastModifiedDate();

    public void setLastModifiedDate(DateTime lastModifiedDate);

    public AdminUser getCreatedBy();

    public void setCreatedBy(AdminUser createdBy);

    public AdminUser getLastModifiedBy();

    public void setLastModifiedBy(AdminUser lastModifiedBy);

    public boolean isDeleted();

    public void setDeleted(boolean deleted);

}

错误堆栈

an assertion failure occurred (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: Subclass has to be binded after it's mother class: com.berwick.dal.TemporalEntity

My尝试解决此问题

将

@MappedSuperclass

添加到临时类 这使得这个错误消失了，但我得到了更多的错误

Duplicate generator name Individual_generator you will likely want to set the property hibernate.jpa.compliance.global_id_generators to false

这个问题与链接线程中的问题非常相似。

编写要嵌入@target注释中的实体类名

   @Embedded
   @Target(TemporalEntity.class)
   private ITemporalEntity temporal;

您不需要通过创建嵌入do it的新对象来紧密耦合临时性。这个问题与链接线程中的问题非常相似。

您不需要通过创建嵌入的新对象来紧密耦合临时性，您是否尝试更改生成器名称？检查此线程，然后回答第二个问题：是的，我知道hibernate不支持继承，这就是为什么我创建一个接口ITemporalEntity，然后创建一个新实例并实现所有字段，如图所示@Embedded private TemporalEntity temporal=新的TemporalEntity（）；您是否尝试更改生成器名称？检查此线程并回答第二个问题：是的，我知道hibernate不支持继承，这就是为什么我创建一个接口ITemporalEntity，然后创建一个新实例并实现所有字段，如图所示@Embedded private TemporalEntity temporal=new TemporalEntity（）；谢谢您的回答，但是我可以通过“可能希望将hibernate.jpa.compliance.global_id_generators属性设置为false”来修复吗？我们可以使用“组合”或“继承”两种模式。有了“@embedded”和“@embeddeble”，您就使用了合成模式。我认为使用@MappedSuperclass就是在利用继承。继承带来了额外的问题。使用组合更好。我做了更改，但仍然得到相同的错误子类必须在其母类后绑定感谢您的回答，但我可以通过“可能希望将hibernate.jpa.compliance.global_id_generators属性设置为false”来修复此问题。我们可以使用“组合”或“继承”两种模式。有了“@embedded”和“@embeddeble”，您就使用了合成模式。我认为使用@MappedSuperclass就是在利用继承。继承带来了额外的问题。使用组合更好。我做了更改，但仍然得到相同的错误，子类必须在其母类之后绑定
