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 WebFlux-based application and how to interoperate with other Reactive Streams-compliant projects like Akka Streams.
- Spring Data lead Oliver Gierke just announced Spring Data Ingalls SR8. This release includes a number of improvements and bug fixes and is a recommended upgrade for all those using the Ingalls release train.
- Spring Boot lead Phil Webb just announced Spring Boot 2.0.0.M5. The new release is now available on the Spring Initializr. It includes preliminary support for Java 9, OAuth 2 client support from Spring Security 5.0, JSON-B support, and a new Spring Session Actuator endpoint.
- Spring Tool Suite lead Martin Lippert just announced Spring Tool Suite 3.9.1. The new release updates to Eclipse Oxygen 1.a, includes JDK 9 and JUnit 5, updated the Spring Boot Dashboard to support insight of running beans in a Spring Boot release. This last thing is so cool! There’s also a refactoring to convert
application.yml, and of course a slew of bug-fixes and improvements.
- Spring ninja Stéphane Nicoll just announced Spring Boot 1.5.8 is now available. The new release includes over 40 fixes, improvements and dependency updates. This is a recommended update.
- Spring Web Services lead Greg Turnquist just announced Spring WS 2.4.1 and 3.0.0.RC1. The 2.4.1 has a few minor patches where 3.0.0.RC1 has a number of major upgrades. The new release baselines on Java 8 and Spring Framework 5.0. If you’re building SOAP-based services, this is for you!
- Have you seen the new Spring Cloud integration for Google Cloud Platform? There’s a lot to like here including integration with core GCP functionality like the project ID, and Runtime Config API, Google Cloud Pub/Sub, Google Cloud SQL, Google Cloud Storage, and Spring Cloud Sleuth integration with Google Stackdriver!
- Spring Data lead Oliver Gierke gave a really nice interview in this podcast on moving from a monolith to a system of systems. Definitely worth a listen!
- Judy Wang has a nice look at how Pivotal Cloud Foundry’s “PCF Metrics” reduce mean-time-to-recovery with better insight.
- Spring Framework founder and Atomist’s CEO Rod Johnson introduces Atomist’s larger perspective of automation of development in this interesting blog post. Atomist provides a number of tools that could be very useful for Spring developers.
- our very own Kenny Bastani looks at using event-driven architectures with a variety of Spring-based technologies in this sample application
- I loved Vedran Pavić’s slides for his presentation, From Zero to Open-Source Hero: Contributing to Spring Projects
- Spring framework founder and Atomist CEO Rod Johnson expands on Atomist’s perspective around the automation of development in this blog post. This is rocket sauce for developers.
- I did a webinar for the folks at JetBrains on Reactive Spring. That webinar is now available here. The webinar introduces Reactor, Spring Framework 5.0 (and Spring WebFlux), Spring Data Kay, Spring Boot 2.0 (and the Actuator), Spring Security 5.0, and the
WebClient, all in the Kotlin language! I hope you enjoy.
- I thought this was pretty cool — Pivotal has a TV commercial!
- Spring testing ninja Sam Brannen put together a nice example on how to write a JUnit 5 Jupiter extension that replaces a common
@Rulefrom the JUnit 4 programming model.
- Redmonk’s James Governor has some insight into the death of Hudson, which Oracle publicly deprecated last week at Oracle OpenWorld, and the prevalence of technologies like Jenkins, and rising stars like Pivotal’s Concourse.
- Also, Redmonk’s James Governor also reviews some of the news from the Cloud Foundry Summit including the emerging details of Kubo, the Kubernetes implementation managed by Pivotal Cloud Foundry.
- This is an oldie but a goodie from Tim Spann at Hortonworks on creating a Spring Boot microservice to read Apache Phoenix Data.
- TechCrunch also had a roundup of the recent Cloud Foundry Summit news, focusing on the integration of Kubernetes for containers into Cloud Foundry. This is ideal for stateful services like Elasticsearch.
- JAXEnter’s Jane Elizabeth has a nice look at Spring Data Kay, the recently released (reactive Spring Data implementation.
- The JAX Innovation awards just took place and, in particular, we’re elated to see that Spring Framework lead Juergen Hoeller has won a JAX Special Jury Award. TL;DR: Spring is one of the largest and continuously maintained codebases and no other person in the Java community has done more to contribute to and shape such a codebase for so long. Thanks to Juergen, the codebase hasn’t required a complete rewrite. As the announcement says, “Thank you, Jürgen, for everything you’ve done for Spring Framework!”
