I’m struggling with this, and I can’t seem to get what I’m after. I added a SynchronizationAdapter (via addOnCompletion), but the exchange passed to the onComplete portion of the route still doesn’t have the headers I’m setting in the Syncronizationadapter. I’ve tried setting the header in both the onAfterRoute and onComplete methods, but no luck. The only place that seems to work is if I add the header in the onBeforeRoute method, but I don’t have enough information at that point to set the header correctly.
The other thing I’d tried previously that I thought would work was simply setting the headers in the Consumer, after it called getProcessor().process(exchange) - but that doesn’t work either. I’m not sure why that doesn’t work - I set headers before I call getProcessor().process(exchange), and they behave as I’d expect. However, anything I do to the exchange after I call getProcessor().process(exchange) doesn’t seem to have any effect? Maybe I need to do something different than just call getProcessor().process(exchange)? Somehow intercept the flow of the exchange after the last processor in the route, but before before camel does whatever it does that makes my copy of the exchange irrelevant? > On Sep 6, 2016, at 2:02 PM, Claus Ibsen <claus.ib...@gmail.com> wrote: > > There is an addOnCompletion on the exchange you can use.
