* Add generic argument to `GenericEndpointSpec`. Since `EndpointSpec#get()` returns `Tuple` with `EndpointFactoryBean` and `MessageHandler` objects it is useful to get deal with specific generic for further `MessageHandler` configuration within `EndpointConfigurer` lambda * Change DSL-methods to get deal deal with those generics. * Add `FileWritingMessageHandler` test to demonstrate it. * Fix bug around double `MessageHandler` bean registration from `DslIntegrationConfigurationInitializer`, when handler is a reference to existing bean.
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.
