解决方案
解决方案二：
楼主你的item不是当前Session取得的，那么至少应该是"游离"状态的才可以(新的ISession可以还原游离的item为持久对象),你这种方式插入新的记录应该是可以的（其他地方代码没错的话)，但更新可能会有问题。可能是这个原因吧：建议这样修改:publicvoidUpdate(AlterationDayPlanitem,ISessionsession){ITransactiontransaction=session.BeginTransaction();try{if(item!=null){session.SaveOrUpdate(item);transaction.Commit();session.Flush();}}catch(HibernateExceptionhex){transaction.Rollback();throwhex;}finally{session.Close();}}
item是ISession取得的，所以和ISession一起传入
解决方案三：
谢谢你的建议，我试一下
