How to rollback message taken from IBM MQ in spring integration

问题

I have a spring integration flow like this:

    1) message-driven-channel-adapter -> 
                 1.1) output-channel connected to -> service-activator -> outbound-channel-adapter (for sending response)
                 1.2) error-channel connected to -> exception-type-router 
                            1.2.1) message is sent to different queues depending on the exception type using outbound-channel-adapter

I have set acknowledge="transacted" in message-driven-channel-adapter. I want to introduce rollback for a specific type of exception, after error-channel.

First, I tried to connect the exception-type-router output to service-activator. But i get exception:

   Code: 

     <service-activator id="rollBackActivator" input-channel="RollBackChannel" 
             ref="errorTransformer" method="rollBackMessage"/>

     public void rollBackMessage(MessagingException  message){       
         TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
     System.out.println("Message rolled back:"+TransactionAspectSupport.currentTransactionStatus().isRollbackOnly());
 }

   Exception:
   org.springframework.messaging.MessageHandlingException: org.springframework.transaction.NoTransactionException: No transaction aspect-managed TransactionStatus in scope

Then, I tried with outbound-channel-adapter expression , But got another exception again

Code:
<outbound-channel-adapter id="rollbackOut" channel="RollBackChannel" 
     expression="T(org.springframework.transaction.interceptor.TransactionAspectSupport).currentTransactionStatus().setRollbackOnly()"/>

 Exception:
 org.springframework.messaging.MessageHandlingException: Expression evaluation failed: T(org.springframework.transaction.interceptor.TransactionAspectSupport).currentTransactionStatus().setRollbackOnly()

Please advise to implement rollback in this scenario.

The container uses local transactions on the session by default. There's no AOP involved. Simply throw an exception and the container will roll back the message.
