Hi Spring fans and welcome to another installment of This Week in Spring! This week I'm in San Francisco for the first, and sure-to-be-amazing, Kotlin Conf 2017. I'll be talking about Spring Boot and Kotlin, and I hope you'll join me if you're around.

We've got a lot to cover this week so let's get to it!

• Spring Batch lead Michael Minella just announced Spring Batch 4.0.0.M5 which includes, among other things, an ItemProcessor implementation that supports Java 8 Function implementations, updated documentation and much more.
• Spring Framework lead Juergen Hoeller announced Spring Framework 5.0.1 which includes a few bug fixes which in turn pick up fixes in Reactor Netty and welcome performance improvements in AspectJ 1.8.12.
• Last week, in another installment of Spring Tips, I looked at HTTP based contracts with Spring Cloud Contract.
• Spring Cloud co-founder Spencer Gibb announced the first release candidate to Spring Cloud Edgware. There are some changes to not in the artifact names for various starters. Spring Cloud Edgware has a lot of new features…

Greetings Spring community,

Spring Web Services has released 3.0.0 for general availability as well as released a minor patch, 2.4.2.RELEASE.

As stated in the previous blog post, the 2.x series will be maintained as long as Spring Framework 4.x is supported, yet any new work will be conducted on the master branch.

The links below include related tickets.

2.4.2 Release Notes | 2.4.2 Documentation.

3.0.0.RELEASE Release Notes | 3.0.0.RELEASE Documentation.

• 3.0.0.RELEASE:

  • Better handling of large attachments to avoid OutOfMemory exceptions.

  • Wss4jSecurityInterceptor enhancements including SAML callbacks

  • SpringSecurityPasswordValidationCallbackHandler improvement to avoid NPE from lack of a logged-in user

  • Fixes to SOAP 1.1/SOAP 1.2 message header handling

  • Fix content-type for Axiom SOAP 1.2

  • Upgrade to latest versions of AspectJ

  • Support for up-and-coming Axiom 1.3 (community contributor who wants to ensure Spring WS and Axiom 1.3 work together).

• 2.4.2.RELEASE:

  • Backporting of the same SpringSecurityPasswordValidationCallbackHandler fix

  • Accidentally moved wss4j 2.x version too far forward to ensure stable compatibility. If you wish to use the very latest wss4j, you must move to the 3.0 version.

Greetings Spring Community and Pivotal GemFire/Apache Geode Users-

One question I constantly get asked is, "What is the difference between Spring Data GemFire and Spring Data Geode?"

Now that Spring Data Geode is part of the Spring Data Release Train, beginning with Kay (see the official release announcement for more details), the timing is finally right to answer this question in an open forum.

To help answer this question, I set 2 simple objectives for both Spring Data GemFire and Spring Data Geode (collectively known as SDG^2 now):

1. First, and most importantly, allow users to seamlessly interchange Spring Data Geode with Spring Data GemFire, and vice versa.

2. Next, help users migrate their Spring Boot, Pivotal GemFire or Apache Geode based applications from their local development environment to a managed environment, like Pivotal CloudFoundry, with little to no code changes at all.

Hi Spring fans! In this tip, we'll look at how to get fast-feedback and do integration testing with Spring Cloud Contract. In this video, we'll focus on HTTP-based services.

Dear Spring Community!

As an event-driven microservices framework, Spring Cloud Stream dramatically simplifies the complexity while developing event-driven applications. The feature capabilities and its benefits are not the focus of this article (to learn more, please review the Reference Guide), but instead, my goal is to show you what the framework has to offer from the testing standpoint, the tools, and techniques. This article is intended to encourage the community to share feedback on the existing testing infrastructure, so any thoughts, comments, or feature requests are welcome! We…

Hi Spring fans! Welcome to another installment of This Week in Spring! Can you believe we're already staring down the end of October 2017? This year has flown by! What a rush! This week I'm home in sunny San Francisco talking to customers and giving talks.

I'll be speaking "at" the vJUG 24 online conference. The conference lasts 24 hours! There's a talk every hour, from as many timezones as possible! I hope you'll join me (and thousands of others) as we look at Reactive Spring at 04:00 GMT on Wednesday.

And, of course, I hope you'll register and join my friend and Grails co-founder Jeff Scott Brown and me for a look at Grails for Spring Developers…

Hi Spring fans! In this tip, we'll look at how to integrate a Spring Boot application with JAX-RS (using the Jersey reference implementation). JAX-RS is a JCP standard for building REST applications.

Greetings Spring community,

Spring Web Services now official has two branches: master (3.0+) and 2.x (maintenance of the old 2.x series). The 2.x series will be maintained as long as Spring Framework 4.x is supported, yet any new work will be conducted on the master branch.

2.4.1.RELEASE is a minor patch release while 3.0.1.RC1 is a major upgrade. The links below include related tickets.

2.4.1 Release Notes | 2.4.1 Documentation.

3.0.0.RC1 Release Notes | 3.0.0.RC1 Documentation.

• 3.0.0.RC1:

  • Rebases Spring Web Services to run on Spring Framework 5.0 and Java 8

  • Drops support for the older Apache WSS4J 1.x line covered by the org.springframework.ws.soap.security.wss4j package. Instead, we only support WSS4J 2.x (in the org.springframework.ws.soap.security.wss4j2 package).

  • Upgrades our XMPP library Smack support to 4.2.

  • This version is planned to be picked up by Spring Boot 2.0 as well as Spring IO Platform Cairo.

• 2.4.1.RELEASE:

  • Maintains our existing baseline of dependencies, making movements on latest supported versions of Spring Framework and Spring Security

  • We’ll maintain the 2.x version as long as Spring Framework 4.x is supported.

  • Based on several of the gaps between Spring Framework 4.x and 5.x, there will be no more compatibility checks of our 2.x branch against Spring Framework 5.x If you need Spring Framework 5, you really need to upgrade to our 3.x branch.

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I've been in Dallas and Austin, Texas, first for customer meetings and then to attend and speak at the epic Reactive Summit. If you're around, don't hesitate to say hi on Twitter! We've got a lot to cover so let's get to it!

Also, I'll be doing a webinar with our friends at OCI on November 9th, 2017, on Grails for the Spring Developer, with my friend and Grails co-founder Jeff Scott Brown. I hope you'll join us!

• Last week, SpringSource co-founder and Spring Framework lead Juergen Hoeller won a JAX Special Jury Award for all of his considerable work since the very beginning of the Spring projects. Thanks to him, the special jury noted, "Spring Framework has never needed a complete rewrite in all of the years it has existed. Instead, it has continuously adapted to the changing trends." Thank you, Juergen, for all that you do.
• Last week, I looked at how to use Scala with a reactive Spring Boot and Spring Webflix-based application…
