EJB调用的Spring事务：Catch中的事务方法需要REQUIRES_NEW，当try的事务方法具有RuntimeException时

Question

我正在从非事务类try块（由另一个EJB类调用）调用事务方法a，该块将引发RuntimeException

然后在catch块中，事务方法b将处理exp。

令人惊讶的是，我必须用“REQUIRES\u NEW”注释方法B，否则程序将出现“Transaction is not active”异常。（stacktrace与此类似）

这是否是因为方法A的事务（标记为RuntimeException的回滚）尚未在catch块中结束。然后方法B没有REQUIRES_NEW重用待回滚事务并在异常中着陆？

但这与我对spring事务的理解背道而驰，因为我认为methodA的事务应该以try块中的methodA结束。methodB将创建一个新事务，因为不再存在任何事务。

//non-transactional method
method(){
    ...
    try{
         classA.methodA();
    }catch(RuntimeException ex){
         classB.methodB(ex);
    }
    ...
}

ClassA
    @Transactional
    methodA(){...}

ClassB
    @Transactional
    methodB(){...}

堆栈跟踪：

我在DB2中使用jBoss

异常要求是方法B

第一行是方法A抛出的错误

Answer 1

唯一的可能性应该是，当EJB类调用method（）时，EJB类中已经打开了一个事务，从而导致所描述的行为。
