Hi Spring fans! In this installment we look briefly at OAuth, as a spec, and then look at how to stand up a Spring Security OAuth-based auth service.

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.

Welcome to another installment of This Week in Spring! This week I'm in London, UK; Paris, France (for the epic Devoxx France event where I'll be speaking with my buddy Matt Raible) and Stuttgart, Germany, where I'll be speaking at conferences and to customers! If you're around, don't hesitate to say "hi"!

• the new release of Spring Tool Suite is jam-packed with new features supporting Spring Boot and Cloud Foundry. Check the New and Noteworthy and get it while it's hot! (I've just gotten a new laptop, so I'm doing that right now, too!)
• last week in the latest installment of Spring Tips I looked at some the various utility classes in the Spring Framework
• I just presented at the premier Voxxed Days CERN event and the organizers interviewed the amazing Spring Framework lead Juergen Hoeller, and me (his biggest fan)

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.

Hi Spring fans! In this installment, we'll look at some of the many *Util classes in the Spring framework. These utility classes are already there and can be a major time-saver, if you know where to look!

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()

Welcome to another installment of This Week in Spring! This week I'm in Omaha, Nebraska, speaking to customers and tonight I'll be presenting at an event co-sponsored by the Omaha, JUG and the local Omaha, Spring Users Group, talking about reactive Spring. Don't be shy, come out and say hi!

• Sébastien Deleuze just introduced the 1.0.0.M1 relese of extensions supporting using Project Reactor in the Kotlin language
• Spring REST Docs lead Andy Wilkinson just announced Spring REST Docs 1.2.0.RC1. Try it out now! For a good example of Spring REST Docs, scroll down and you'll see a very nice one from a community member.
