When deploying my microservice on spring cloud dataflow I get the following log:
No bean named 'errorChannel' has been explicitly defined. Therefore, a default PublishSubscribeChannel will be created
how do I direct error flows?
My guess is to create an errorChannel bean (as the message says). But I did not find any docs about it nor sample usages.
For example, I have a sink that executes an Insert on a database and want to direct it elsewhere if insert fails.
The default errorChannel bean has a LoggingHandler subscribed to it.
If you define your own errorHandler channel, it won't get the default LoggingHandler.
The error channel is automatically wired in.
Each consumer (or @StreamListener) gets a dedicated error channel binding.group.errors which is bridged to the global errorChannel.
You can add a @ServiceActivator to consume ErrorMessages from either of these channels.
Error channels are not applied on the producer side; you have to catch the exception yourself.
