从Hibernate 4迁移到5

Question

从hibernate 4.3迁移到hibernate 5时遇到了一些问题。 我正在开发一个主要项目，我们使用SequenceHiLoGenerator来生成现在已弃用的id。如何在没有重大变化的情况下更新此内容？

这是我的hibernate 4.3代码。

public class KSequenceGenerator extends SequenceHiLoGenerator {
@Override
public Serializable generate(SessionImplementor session, Object object) throws HibernateException {
    Serializable id = session.getEntityPersister(null, object).getClassMetadata().getIdentifier(object, session);
    return id != null ? id : super.generate(session, object);
}

在EJB中：

@GenericGenerator(name="id_gen", strategy="com.or.nk.ob.base.KSequenceGenerator", parameters = {@org.hibernate.annotations.Parameter(name = KSequenceGenerator.SEQUENCE, value = "building_id_seq")})

现在我有：

public class KSequenceGenerator extends SequenceStyleGenerator { 
public static final String SEQUENCE = "sequence";

@Override public Serializable generate(SharedSessionContractImplementor session, Object object) throws HibernateException { 
    Serializable id = session.getEntityPersister(null, object).getClassMetadata().getIdentifier(object, session); 
    return id != null ? id : super.generate(session, object); 
} 

}

ID：

@Id
@Column(name = "ID")
@GeneratedValue(generator = "id_gen", strategy = GenerationType.SEQUENCE)
public Long getId() {
    return id;
}
