What happened at Spring I/O 2022 conference? Spring Boot 3 is coming
My review as a participant, Presentation videos, and more
Spring I/O 2022 was terrific for me, it came back as an in-person event after two years, and I attended this fantastic conference in Barcelona (26–27 May 2022). It was the 9th in-person edition of this conference, with more than 60 presentations, six workshops, and 1200 attendees. I met a lot of excellent Java and Spring developers, and the conference focused on the Spring Framework ecosystem as expected.

Open ceremony and Keynote
After a lovely opening ceremony and welcome speech, the most important speech was from Juergen Hoeller (Spring Framework co-founder and project lead) about Spring Framework 6 and Spring Boot 3. Juergen said Spring Framework 6 is a new generation of this framework for the next decade.
I think the most important announcement for Spring Framework 6 was to increase the framework baseline to JDK 17+ and support AOT (Ahead-Of-Time) processing feature to support GraalVM native executables and more.
Spring Framework 6.0 GA will be released in November 2022.

Conference sessions
According to the schedule, for every day at specific times, there were 3 or 4 different presentations in 3 or 4 different rooms (Track) at the same time where you needed to choose one presentation to participate in, and there were three workshops for every day of the conference.
There were a lot of engaging presentations that I am sure in the coming weeks and the Spring I/O youtube channel will publish in its channel. You can watch them on this playlist.
Of all of them, the Bootiful Kubernetes Operators by Cora Iberkleid and Josh Long was more appealing to me than the rest. This excellent presentation showed how to extend Kubernetes by writing a Kubernetes controller using Spring Boot, compiling it to native executables using GraalVM and Spring Native, and finally installing it on a Kubernetes cluster. Fortunately, the video of this presentation is available on the Spring I/O YouTube channel right now:
Spring I/O founder Sergi Almar
Josh long, in his awesome (Bootiful podcast) podcast, just had an interesting interview with Spring I/O founder Sergi Almar. It is worth hearing everything about Spring I/O from its founder Sergi Almar:
Final Thoughts
It was awesome to meet so many folks from Spring Community in the beautiful city of Barcelona. I hope I can attend Spring I/O 2023 next year.
