Dynamic routing slips consumed after first execution
If you change ProofTest.verify_scenario_four
to send the same message twice:
@Test
public void verify_scenario_four() throws Exception {
String[] profiles = {"PostProcessorB"};
AnnotationConfigApplicationContext context = runContext(profiles);
DirectChannel inputMessageChannel = context.getBean("inputMessageChannel", DirectChannel.class);
DirectChannel outputMessageChannel = context.getBean("outputMessageChannel", DirectChannel.class);
outputMessageChannel.subscribe(message -> System.out.println("scenario four: " + message.getPayload()));
Message<String> startMessage = MessageBuilder.withPayload("start").build();
inputMessageChannel.send(startMessage);
inputMessageChannel.send(startMessage); // same message again
context.close();
}
private AnnotationConfigApplicationContext runContext(String... profiles) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
context.getEnvironment()
.setActiveProfiles(profiles);
context.register(BaseIntegrationConfiguration.class, PreProcessorAIntegrationConfiguration.class,
PrePostProcessorBIntegrationConfiguration.class, PostProcessorCIntegrationConfiguration.class);
context.refresh();
return context;
}
The resulting output shows that post-process B is only executed the first time:
scenario four: start->sending to pre-processing channel->beginning pre-processing->processing message->beginning post-processing->post-process B
scenario four: start->sending to pre-processing channel->beginning pre-processing->processing message->beginning post-processing
The reason is apparently that the RoutingSlipRouteStrategy is stateful, you need to create a new instance of it each time you create the routingSlip header.
