Hibernate:save()后获取oracle 从增主键和数据生成的逐渐不一致

public boolean save(Cardownerinfo ownerinfo) {        Session session = HibernateSessionFactory.getSession();        Transaction tx = null;        try {            tx = session.beginTransaction();            session.save(ownerinfo);            tx.commit();            return true;        } catch (RuntimeException re) {            tx.rollback();            log.error("==CardownerinfoSevices save failed==", re);            re.printStackTrace();        } finally {            session.close();        }        return false;    }

public void testSave() {        Cardownerinfo ownerinfo = new Cardownerinfo();        ownerinfo.setOwnername("人卡465");        ownerinfo.setCreatetime(new Date());        CardownerinfoSevices ownerinfoSer = new CardownerinfoSevices();        boolean save = ownerinfoSer.save(ownerinfo);        if (save) {            System.out.println(ownerinfo.getOwnerid());            System.out.println("successfuly");        } else {            System.out.println("failed");        }    }
