This Week in Spring - February 20th, 2018

Engineering | Josh Long | February 20, 2018 | ...

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm speaking at the San Diego JUG with Mario Gray on testing with Spring. Then I'm off to the IBM Index conference here in San Francisco where I'll be talking about building reactive microservices, and then it's off to Devnexus in Atlanta, GA, where I'll be talking about Kotlin and testing. I hope you'll join me and say hi if you're nearby.

  • Stéphane Nicoll has just announced Spring Framework 5.0.4.
  • Check out this whitepaper on building flexible Spring Cloud Data Flow data pipelines
  • It's now even easier to use Spring Cloud Stream from the Spring Initializr: now you need only choose a binder implementation (Kafka, or RabbitMQ) and then choose whether you want the implementation to be reactive or not, and you're off to the races!
  • Spring Cloud Task lead Michael Minella just announced Spring Cloud Task 2.0.0.M3. The new release includes smarter default behavior when an application closes, the ability to restrict tasks from running concurrently,

Spring Cloud Contract in a polyglot world

Engineering | Marcin Grzejszczak | February 13, 2018 | ...

This article contains a short reminder of what Contract Testing is, how Spring Cloud Contract implements it, and how Spring Cloud Contract can be used in a polyglot world.

What is Contract Testing

In order to increase the certainty that our systems behave properly, we write different types of tests. According to the test pyramid the main types of tests are unit, integration, and UI. The more complex the tests, the more time and effort they require and the more brittle they become.

In a distributed system, one of the most frequent problems is testing integrations between applications. Let’s assume that your service sends a REST request to another application. When using Spring Boot, you can write a @SpringBootTest in which you test that behavior. You set up a Spring context, you prepare a request to be sent…​ and where do you send it? You haven’t started the other application, so you get a Connection Refused

Spring Web Flow 2.5 RC1 is available

Engineering | Rossen Stoyanchev | February 12, 2018 | ...

The first and only release candidate planned for Spring Web Flow 2.5 is now available from the Spring Milestones repository. The samples repository has been updated to use it.

This release provides an upgrade path to Spring Framework 5 along with Java 8, Servlet 3.1, Hibernate 5, Tiles 3, and JSF 2.2 as minimum requirements.

In this release "spring-js" has been merged with "spring-webflow" so there is no longer a separate "spring-js" module. As a result some configuration classes have changed packages. The "spring-js-resources" module is still available but as an optional module that must be…

Note

See the latest announcements on Announcing the Spring Authorization Server and Spring Security OAuth 2.0 Roadmap Update

Current State

The current state of OAuth 2.0 Support, within the Spring projects portfolio, is spread out between Spring Security OAuth, Spring Cloud Security, Spring Boot 1.5.x, and the new support introduced in Spring Security 5. As a user of OAuth, you may be asking, "Which project(s) do I use? And why has Spring Security 5 introduced new support into the mix?"

To put it simply, there was a need to unify the OAuth 2.0 support into one project in order to provide a…
