How to correlate Camel ExchangeCompletedEvent and multicast/split?

I have a scenario where I use ExchangeCompleteEvent to print some log.

I have Multicast in my Route as below :-

from("{{route.from}}")
.multicast()
.to("{{route.to1}}")
.to("{{route.to2}}");

The ExchangeCompleteEvent is called 3 times in such case. I think two are for above two .to calls and one is for main exchange.

I want to use it only for main exchange i.e the last call, how can I correlate the ExchangeCompleteEvent with main exchange ?

Solution

  • The child exchanges will have an exchange property stored (key is the field Exchange.CORRELATION_ID, eg CamelCorrelationId) which point to their parent exchange id. So you can look for that property to see if its present or not. If not then its the parent exchange.
