Is there a reason you don't want to throw an exception? If you have
multiple processors in a row like that all of which might throw exceptions
that certainly seems reasonable. The other possibility here is to inject
your processors into one another in a chain of responsibility. I usually
use a chain of Pojos if I need that but it would be similar. Don't copy
this as I'm writing it in plain text after a long day flying and it's not
coming out of an IDE. Plus I never use Processors/Exchanges and use
blueprint so don't know if the XML would match what you're after. But you
get the idea.
public class MyProcessor implements Processor {
Processor nextProcessor;
//put in getters/setters
public void process(Exchange exchange) throws Exception {
// do something...
//if logic is correct then call next processor otherwise return.
nextProcessor.process(exchange);
}
}
<bean id="processorChain" class="my.first.Processor">
<property name="nextProcessor" ref="secondProcessor"/>
</bean>
etc.
<route>
<from uri="direct:in">
<bean ref="processorChain"/>
</route>
