Hi Spring fans! We've now finished two seasons - 11 episodes and a recap post each - of Spring Tips. I'm going to take a little while to dream up some more content and, before you know it, we'll be back at it again! I'm always interested in hearing proposed topics so if you have some, please, by all means, shout it out loud to me on Twitter (@starbuxman) or by email ([email protected]).

The motivations for me in doing these Spring Tips are:

• revisit traditional topics in light of Spring Boot and
• highlight parts of the amazing Spring ecosystem that, for one reason or another, don't get enough attention.

Welcome to another installation of This Week in Spring!

• Spring Integration ninja Artem Bilan just announced Spring Integration 5.0.M3. The new release includes an integration test framework, speed improvements, support for the Spring 5 reactive WebClient, retroactive restoration of file trees when using the (S)FTP and AWS S3 inbound adapters, a smarter SOAP web-services gateway, and much more.
• Spring Integration lead Gary Russell just announced Spring for Apache Kafka 1.2.0 and 1.1.4
• Andy Wilkinson just debuted a look at the new Gradle Spring Boot 2.0 plugin
• in last week's Spring Tips I looked at how to standup a Spring Cloud Security-powered OAuth auth…

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.…

One of the main themes of Spring Boot 2.0 M1 is a range of significant improvements to its Gradle plugin. Many of those improvements have just been merged and are available in the latest Spring Boot snapshots. There's a few weeks until Spring Boot 2.0.0.M1 will be released at the beginning of May and we'd love to hear your early feedback on the new plugin before then.

You can read more about the plugin's capabilities in its reference and API documentation.

Trying the new plugin

The new plugin requires Gradle 3.4 or later. Like the rest of Spring Boot, snapshots are published to https://repo.spring.io/libs-snapshot. The easiest way to use a snapshot is to create a new Gradle project on start.spring.io…

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)
• don't miss the upcoming webinar on April 13th, Spring Boot Under the Hood
• Check out the Spring Team and Pivotal at OSCON Austin 2017…

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.
