从休眠乐观锁定异常中恢复

Question

我最近遇到了一个奇怪的问题。我试图优雅地处理过时的状态异常。但是在catch块中，它仍然会引发异常。以下是代码段

public void saveObject(Object ob){
   try{
      sessionFactory.getCurrentSession().saveOrUpdate(ob);
   }catch(org.springframework.orm.hibernate5.HibernateOptimisticLockingFailureException e){
       object latestObject = // get latest object from db;
       copyFieldsFromObToLatestObject(ob,latestObject);
       // print the version of of both object

    LOGGER.info(" ui_version="+ob.getVersion().longValue()+" 
                 entity_version="+latestObject.getVersion().longValue());
          // the ui _version is less than entity_ version as expected 

        sessionFactory.getCurrentSession().saveOrUpdate(latestObject); // at this line I still get the same optimistic locking exception 

   }
}
 /**

 ob2 is the latest object which contains the correct  version hence copying the fields from previous object to this latest object
**/
private void copyFieldsFromObToLatestObject(ob1,ob2){
    ob2.setA(ob1.getA())..
   so on
}

有人可以看看这个吗？我无法得到正确处理后仍引发乐观锁定异常的原因

Answer 1

在catch块中，您应该捕获抛出的异常并要处理。你抓住了Optimistic locking exception。我什至无法想象这是如何编译的。尝试用堆栈跟踪中的异常名称替换它吗？

Answer 2

问题已解决，我也在to字段中复制了关联的子实体的版本，这导致保存较旧的子实体版本并因此导致错误
