我用s2sh做购物网站,里面用到了版本控制version,save和delete没有问题,但update就显示出错。
我一运行就点update,所以不存在已有一个线程在。
我觉得是这个问题,不知对不对。

以下是错误代码:
org.springframework.orm.hibernate4.HibernateOptimisticLockingFailureException: Object of class [com.fangyun.entity.Product] with identifier [0]: optimistic locking failed; nested exception is org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.fangyun.entity.Product#0]

org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.fangyun.entity.Product#0]

The updated primary key is 0 and there is no corresponding data. You can print the data before updating and you will know!
