Question

我不熟悉hibernate，concurrrency问题和陈旧的异常。

我在高并发环境中使用GORM处理grails。乐观锁定打开，我在事务服务中使用静态锁定方法。

        for(Entity entity : entityList) {
            //refresh and lock for update
            entity.refresh();
            entity = Entity.lock(entity.id)
            entity.setSomeData(new Date());
            entity.save()
        }

在这种情况下，以某种方式可能会出现HibernateOptimisticLockingFailureException吗？

请注意堆栈跟踪：

静态Entity.lock（）如何抛出过时的对象异常？

甚至使用静态锁定方法的陈旧例外
