Add test case for `@MessageEndpoint` to et deal with channel from `IntegrationFlow` As far as `AbstractMethodAnnotationPostProcessor` tries to resolve `channel` on endpoint creation, the `IntegrationFlow` processing can't be done in the `BPP`, because `MessagingAnnotationPostProcessor` may parse annotations for bean before `IntegrationFlowBeanPostProcessor` will do its stuff.
Spring Integration Java DSL
The Spring Integration JavaConfig and DSL extension. Provides a set of convenient Builders and fluent API to configure
Spring Integration message flows from Spring @Configuration classes.
Example Configurations
@Configuration
@EnableIntegration
public class MyConfiguration {
@Bean
public MessageSource<?> integerMessageSource() {
MethodInvokingMessageSource source = new MethodInvokingMessageSource();
source.setObject(new AtomicInteger());
source.setMethodName("getAndIncrement");
return source;
}
@Bean
public DirectChannel inputChannel() {
return new DirectChannel();
}
@Bean
public IntegrationFlow myFlow() {
PollerMetadata pollerMetadata = new PollerMetadata();
pollerMetadata.setTrigger(new PeriodicTrigger(100));
return IntegrationFlows.from(this.integerMessageSource())
.poll(this.inputChannel(), pollerMetadata)
.transform((Integer p) -> p * 2)
.transform(Object::toString)
.channel(new QueueChannel())
.build();
}
}
As the result after ApplicationContext start up will be created Spring Integration endpoints and Message Channels as it is after XML parsing.
Such configuration can be used to replace XML configuration or together with that.
