当异常在子方法中抛出时，事务不会回滚 - Spring

Question

I have a method Service method - SampleServiceImpl(). I have declared the Service method as following:

@Transactional
@Override
public sampleDTO SampleServiceImpl(SampleDTO sampleDTO) throws SampleException, ParseException { 
   // Method call to methodA.
   createDataA(sampleDTO);
   // Method call to methodB.
   createDataB(sampleDTO);

   return sampleDTO ;
}

Here the DataA is created and it does not throw any exception. But in DataB, we are trying to create DataB based on DataA. Due to some logic, we cannot create DataB. So, we throw a Sample Exception like:

count = checkIfDataBExisting(sampleDTO);
if(count == 1){
   throw new SampleException(ErrorConstants.DATA_B_EXISTING);
}

But the problem is, the transaction that got committed during createDataA(sampleDTO) method call, does not get rolled Back.

Why does this don't actually work? I'm bit confused with this behavior.

EDIT:1

createData1(sampleDTO) method -

private ADTO createDataA(SampleDTO sampleDTO) throws SampleException{
    ADTO aDTO = null;    
    try {
        //CREATE NEW WORK DRIVER
        aDTO = createNewDataA(sampleDTO);

        //Other arbitary database transactions occurs after creation of AData.


} catch (SampleException exc) {
    SampleException newException = new SampleException (exc.getExceptionObject().getExceptionCode(), exc);

    throw newException ;
}
return aDTO;
}

EDIT2:

SampleException Declaration -

public class SampleException extends Exception{
    //Definitions and Declarations.
}

By default declarative transactions rollback only for Runtime exceptions. SampleException has to be RuntimeException for the Transaction to be rolled back.

Your method signature:

public sampleDTO SampleServiceImpl(SampleDTO sampleDTO) throws SampleException, ParseException

makes me think that SampleException is a checked one.

See the documentation for @Transactional :

If no rules are relevant to the exception, it will be treated like DefaultTransactionAttribute (rolling back on RuntimeException and Error but not on checked exceptions).

You can either make SampleException extends RuntimeException or set the rollbackFor attribute of @Transactional .
