This Week in Spring - July 26th, 2016

Welcome to another installation of This Week in Spring! This week I’m mostly in San Francisco and Saint Louis, busily preparing for the big event next week!

This is my favorite time of year! As we lead to SpringOne Platform, there’s so much good stuff being released that one can hardly keep up! I am really looking forward to this year’s SpringOne Platform show, coming in early August. It’s an amazing time to build applications, and SpringOne Platform is in a unique position to capture the larger discussion: why do we #devops, #cloud, #agile, or #microservice? Join the discussion August 1-4, 2016 in beautiful Las Vegas and let’s find out!

Spring Integration AWS 1.0.0 GA available now

Dear Spring Community,

It is my pleasure to announce that the Spring Integration AWS 1.0.0.RELEASE is available now.

As usual, thanks to the community for any feedback and contributions!

This release contains several critical bug fixes (mostly community driven) and aligns requirements of the upcoming Spring Cloud Stream Application Starters release.

We haven’t added any new features since the latest announcement and have concentrated mostly on improvements, bug fixes and integration testing, to deliver this product as soon as possible. For the next 1.1 version we would like to hear from you about priorities since there are still many Amazon features to cover.

Spring Cloud Contract 1.0.0.M1 Released

On behalf of the Spring Cloud team it is my pleasure to announce the 1.0.0.M1 release of the new Spring Cloud project called Spring Cloud Contract. You can grab it from the Spring’s milestone repository or even better - go to start.spring.io and pick it from there.

Spring Cloud Contract

The microservice approach has plenty of benefits but also introduces complexity. This is an inevitable result of working with distributed systems: with increasing complexity inevitably more questions are posed. In this article we show how to test microservices and create a better API by using the Consumer Driven Contracts approach. In order to make testing microservices easier we are more than happy to introduce a new project in the family of Spring Cloud projects - Spring Cloud Contract. This project provides support for Consumer Driven Contracts and service schemas in Spring applications, covering a range of options for writing tests, publishing them as assets, asserting that a contract is kept by producers and consumers, for HTTP and message-based interactions.

This article is a companion of another recent one on how to do zero-downtime deployment with a database.

Notes on Reactive Programming Part III: A Simple HTTP Server Application

In this article we continue the series on Reactive Programming, and the focus is less on learning the basic APIs and more on more concrete use cases and writing code that actually does something useful. We will see how Reactive is a useful abstraction for concurrent programming, but also that it has some very low level features that we should learn to treat with respect and caution. If we start to use these features to their full potential we can take control of layers in our application that previously were invisible, hidden by containers, platforms and frameworks.

It is my pleasure to announce that the Spring for Apache Kafka 1.0.2 maintenance release is available now.
