我们不能捕获StaleObjectStateException吗？我有使用StaleObjectStateException的catch块，所以当方法抛出此错误时，它会进入此catch块，但仍会再次抛出相同的异常。 我知道这个例外即将到来的原因，但我想抓住这个例外并继续前进。

是的，你可以捕获异常。
如果异常没有传播到您尝试捕获它的位置，则可能会出现类似这样的问题。例如：
从堆栈跟踪来看，我说这是第二种解释。已捕获原始异常并已创建包装它的HibernateOptimisticLockingFailureException。这是你看到的后一个例外。
如果要专门处理原始异常，可能需要捕获HibernateOptimisticLockingFailureException（或超类），然后调用异常对象getMostSpecificCause()以提取原始异常诊断

使用此：
@Transactional(propagation = Propagation.REQUIRES_NEW,readOnly=true)
