Hi, Spring fans! Welcome to another installment of This Month in Spring! How are you? It's September 26th, 2023, and I am in sunny Singapore for SpringOne at VMWare Explore Singapore. If you're around, don't forget to say hi!
I know, I know, when we last chatted I was wrapping up at SpringOne in Las Vegas, but we're holding another one! It's a lot of fun, too.
It's gonna be a fun and busy week in Singapore, and then next week I'm off to Antwerp, Belgium, for the amazing Devoxx BE 2023. Then, I'm off to Morocco, for Devoxx MA 2023. Then, I'm off to Amsterdam for SpringOne Tour Amsterdam. If you're in any of these places, do not hesitate to reach out and say hi! I'd love to chat!
We've got a ton of things to cover so let's dive right into it!
- I love Java, and I think it's one of the most productive ways to write systems, so I wrote a quick explainer I'd appreciate you sharing with the world on how to, assuming you've got a *nix environment and nothing else installed, go from zero to hero with Java 21 and Spring Boot 3.
- Java 21 is here, and I wrote a huuuuge explainer about all the new features in this blog here: Hello, Java 21
- If you want to watch your knowledge instead of read it, you might watch this video instead
- Want to learn more about one key dimension of the new features in Java 21? Check out this article from Java language architect Brian Goetz from 2022: Data Oriented Programming in Java

- Piotr Mińkowski has a great point: If you are looking for a gRPC and Spring Boot integration [you can use that starter](https://github.com/LogNet/grpc-spring-boot-starter. In comparison to more popular
net.devh:grpc-spring-boot-starter- it is more often released and has support for Spring Boot v3. - Spring Test lead Sam Brannen shares that Spring Framework 6.1 M5 introduces
@ContextCustomizerFactoriesto register aContextCustomizerFactory, superseding@ContextConfiguration(initializers)when you need access to the test class. Nice! - the good and the great Dr. David Syer has an interesting project here that looks at aggregating OpenAPI schema, here spring-projects-experimental/spring-openapi-aggregator
- Speaking of the good and great Dr. Syer, he and I are doing a keynote at this year's SpringOne in Singapore, and we'll be speaking at the local Java User Group there, too.
