spring poller executer channel implementation - spring-integration

Question

After my poller fetches data from DB, I am calling an external service.
After getting response from that service, I want to do call another systems in a separate thread. Means, after getting response, my poller should take another record and send.In addition calling other systems should work in parallel.
For this I used a direct channel for receiving the data from DB. Used a service activator for sending request to external service. The response is passed to an executer channel.can anyone please tell me whether the below configuration is correct for the scenario ?
For clarity I am sharing the poller.xml

Answer 1

No; it's not correct (it is almost correct).
<stream:stdout-channel-adapter id="executerchannel"/>
this overrides your executor channel definition (an outbound adapter with no channel attribute creates a channel with that id).
You will end up with a simple direct channel with 2 subscribers (stdout and your service activator) - they will get alternate messages.
I am not sure why you added that element; remove it or subscribe it to some other channel.
If you want it to go to both places; change the channel to a <publish-subscribe-channel/> with an executor.
