This Week in Spring: Manifest Editing, Boot 2.0M1, and Kotlin

Welcome to another installment of This Week in Spring! This week I’m in Amsterdam, NL and Essen, DE, talking to customers about cloud-native transformation. We’ve got a lot to cover so let’s get to it.

• Spring Tool Suite lead Martin Lippert just announced a preview of Concourse Pipeline and Cloud Foundry manifest editing support releases as a language server. These language servers can be used by any IDE or text editor that supports them, including in this case Microsoft’s Visual Studio Code and later STS itself.
• Spring Cloud Stream ninja Soby Chako just announced Spring Cloud Stream.SR2
• Simon Baslé just announced the Reactor Bismuth release train M1
• Stéphane Nicoll just announced Spring Boot 2.0M1! It’s finally here! Get the bits of the first major release towards a reactive Spring Boot 2.0. There’s so much good stuff, including an updated Gradle plugin, relaxed binding improvements, major dependency upgrades and so much more!
• I think this article by Paweł Chudzik on poor man’s batch solutions — iterating over large datasets — was very interesting. The conclusion is obvious: if you want to scroll through a large number of records then use a java.util.Stream<T> finder query in your Spring Data repository. That’s one obvious conclusion. May I also humbly recommend that you look at Spring Batch and have a rich man’s batch at poor man’s prices?
• Want easier handling form encoded JSON in Spring MVC? Vote for this issue!
• I liked this walkthrough on how to implement a forgotten password flow with Spring Boot on the Code by Amir blog by Amir Boroumand.
• Amir Boroumand also has a nice walkthrough on creating a REST API with Spring Boot
• Our friends at JDriven are doing what appears to be an awesome (though I think Dutch-language) on MQTT and Spring Cloud Stream and Spring Cloud Data Flow.
• I liked this fairly approachable look at how to deploy Hashicorp Vault to Cloud Foundry by our very own Toshiaki Maki.
• Want a bit of insight into what the future of Serverless looks for Spring? Check out the slides to the good Dr. Dave Syer’s presentation on Spring Cloud Function at Spring IO.
• WeaveWorks’ Scope is now available and supports Cloud Foundry.
• I liked this rant from Steve Yegge on why Kotlin is a nice language. Interesting reading!
