Java 从Hibernate乐观锁定异常中恢复
我最近一直面临一个奇怪的问题。我试图优雅地处理陈旧状态异常。但在catch块中，它仍然抛出异常。下面是代码片段Java 从Hibernate乐观锁定异常中恢复,java,spring,hibernate,optimistic-locking,staleobjectstateexception,Java,Spring,Hibernate,Optimistic Locking,Staleobjectstateexception,我最近一直面临一个奇怪的问题。我试图优雅地处理陈旧状态异常。但在catch块中，它仍然抛出异常。下面是代码片段 public void saveObject(Object ob){ try{ sessionFactory.getCurrentSession().saveOrUpdate(ob); }catch(org.springframework.orm.hibernate5.HibernateOptimisticLockingFailureException e){

在catch块中，您应该捕获抛出的和要处理的异常。您捕获的是
乐观锁定异常
