We are pleased to announce that these maintenance releases of Spring for Apache Kafka are now available, 1.2.0.RELEASE and 1.1.4.RELEASE.

These versions include several bug fixes and improvements, as well as introduce support for KStreams.

They are functionally equivalent; the 1.2.0.RELEASE is based on the 0.10.2.0 kafka-clients jar and 1.1.4.RELEASE can be used with 0.10.0.x and 0.10.1.x.

While 1.1.4.RELEASE will work at runtime with a 0.10.2.x client library, some breaking changes in the embedded kafka API means that the embedded kafka Junit @Rule in spring-kafka-test will not work and 1.2.…

The Spring Integration team is pleased to announce that the third milestone for the Spring Integration 5.0 release (5.0.0.M3) is now available.

53 JIRAs (and some GitHub issues) made into this release, including bug fixes and a number of new features. Some highlights since the previous Milestone 2:

• Initial implementation for a Spring Integration Testing Framework - the @SpringIntegrationTest annotation for test classes and MockIntegration factory help you to write unit tests for integration flows and channel adapters. We intend to flush out this capability with more features before GA, including more mocking, verifications and some send-and-receive utilities to test components in isolation. Feedback is welcome!

• POJO handler method invocations (@ServiceActivator, @Transformer etc., or such methods invoked from XML definitions) now use InvocableHandlerMethod by default. Together with the ConfigurableCompositeMessageConverter and @Default utilities that allows us to implement conditional method invocation scenarios based on the Content-Type and target method arguments resolution. To restore the previous SpEL-based behavior, the @UseSpelInvoker method-level annotation is provided.

We are pleased to announce that the third milestone for the Spring AMQP 2.0 release (2.0.0.M3) is now available.

36 JIRA Issues are included in this release, including bug fixes and a number of new features:

• Initial support for broker-less integration testing - the TestRabbitTemplate discovers listener containers in the application context and invokes those containers' listeners for send() and sendAndReceive() operations. We intend to flush out this capability with more features before GA, including routing, and simulation of the various exchange types supported by RabbitMQ. Feedback is welcome.

• Rollback with an external transaction manager is now consistent with local transactions.

• The 4.1.x amqp-client library is now the default.

• The RabbitTemplate now has an invoke() method which allows multiple operations to be performed sequentially on the same channel. This also enables features such as waitForConfirmsOrDie() provided by the underlying library, when sending multiple messages to the same channel.

Update: Kotlin is now natively supported by reactor-core and reactor-test without requiring any additional extensions.

I am excited to announce the release of the first milestone of Reactor Kotlin Extensions, which provides Kotlin extensions for Reactor API.

It provides support for Kotlin types like KClass, takes advantage of Kotlin reified type parameters and provide various extensions to allow more expressive code. You can see bellow a quick comparaison of Reactor with Java versus Reactor with Kotlin + extensions.

…

Java	Kotlin with extensions
Mono.just("foo")	"foo".toMono()
Flux.fromIterable(list)	list.toFlux()
Mono.error(new RuntimeException())	RuntimeException().toMono()
Flux.error(new RuntimeException())	RuntimeException().toFlux()
flux.ofType(Foo.class)	flux.ofType<Foo>() or flux.ofType(Foo::class)
StepVerifier.create(flux).verifyComplete()	flux.test().verifyComplete()
