Hi, Spring fans! What's shaking? It's one of those weeks where, even though the thing I wanted to happen - a vacation with the family - didn't happen, what did happen - accidentally lots of free time with no meetings - has turned out wonderfully. It was all I could do to pry myself from the IDE to pull together this week's roundup, but I am glad I did! There's a ton of great stuff there. Let's dive into it.

• I love this post by the good Dr. David Syer: "Wiremock" for RSocket
• In this week's installment of A Bootiful Podcast, JHipster creator and Microsoft Java Developer Advocacy manager Julien Dubois
• Kotlin 1.5.0 Release Community Event
• This is super interesting: OpenJDK on RISC-V - an update from Alibaba
• To all the readers of my little book so far: Thank you! Schiko on Twitter: "Reactive Spring" by @starbuxman is without a doubt the best programming book i've ever read. Thanks Josh! https://t.co/nAzdK4kNyn #springboot #Java" / Twitter

Dear Spring Community,

Today it’s my pleasure to announce releases of Spring Integration for Amazon Web Services extension versions 2.5.1 and Spring Cloud Stream Binder for AWS Kinesis 2.2.0.

These releases can be downloaded from Maven Central:

compile 'org.springframework.integration:spring-integration-aws:2.5.1'

If you don’t use Kinesis Binder. Or via Binder dependency:

compile 'org.springframework.cloud:spring-cloud-stream-binder-kinesis:2.2.0'

Spring Integration for AWS extension of 2.5.1 has some minor bug fixes after the previous 2.5.0 announcement.

The Spring Cloud Stream Binder for AWS Kinesis 2.2.0 is the first release in the project generation which is based on a new independent Spring Cloud for AWS artifact. It also was upgraded to the latest Spring Cloud 2020.0.3…

Hi, Spring fans! In this installment Josh Long (@starbuxman) talks to JHipster creator and Microsoft Java Developer Advocacy manager Julien Dubois (@juliendubois)

If you have an application that connects to an RSocket server at runtime, how do you test it? We need a way for a test to start a server and tell us where it is listening, and then we need to be able to register request and response examples (a.k.a. "contracts"). That’s what this project provides - it’s like Wiremock but for RSocket.

Getting Started

The easiest way to use the project is as a JUnit (Jupiter) extension, e.g:

@SpringBootTest
@ExtendWith(RSocketServerExtension.class)
class SocketsApplicationTests {
	...
}

With this extension installed the Spring Boot tests will run with an RSocket server listening on a port given by test.rsocket.server.port, so the test can connect directly to it, or (more likely) the code that it is testing will connect to it. You might need to tell it where to connect via the @SpringBootTest annotation, e.g. if the application is looking for a property at runtime called rsocket.port…

Hi, Spring fans! Welcome to another installment of This Week in Spring! How're you doing? I'm doing well! I hope you're doing well, too. Can you believe we've just entered the month of June 2021? WHERE HAS THIS YEAR GONE ALREADY! It's insane. But, the march of Spring continues, and with each passing week a ton of new stuff to talk about arrives. Let's get into it!

• In last week's episode of A Bootiful Podcast, I talked to Micrometer-lead Tommy Ludwig
• Announcing the general availability of the Azure Spring Cloud Terraform provider
• Cool to see an Azure Spring Cloud success story in the MSBuild keynote
• Get your reactive microservices to Kubernetes with Spring Boot and JHipster
• Michael Coté asks on Twitter: What's an API Gateway and why would you use it? Also, what does "business value" mean here? See the full interview with Rita Marinachi, Chris Sterling, and me to hear even more and also a how API gateways fit with service meshes.

Hi, Spring fans! Welcome to another installment of This Week in Spring! How're you doing? I'm still fresh off my little vacation last week, feeling fantastic. I've spent the last several days working with Spring Boot and Spring Native and I have to tell you, they're epic.

It's gotten to the point where I sometimes spend time working on enabling Spring Native integrations for other projects - it really makes some third party abstractions come alive! It's hard to know what the right comparison is. There's not much you can do in this life that results in such an instantaneous, night-and-day difference in performance and memory profile with so few (user-visibile) changes. Imagine snapping your fingers and having your luxury hypercar (Spring Boot in this metaphor) transform into an equally capable, and very…
