This Month in Spring - December 2022

December 7, 2022 Josh Long

Hi, Spring fans! Welcome to another installment of This Month in Spring! As I write this it's early December, 2022, and that means this will be the last installment of This Month in Spring until the new year!

Since we last spoke, we've released Spring Framework 6.0 and Spring Boot 3.0. I did a video covering some of my favorite features in the new Spring Framework 6.0 release and then I did another video introducing the new ahead-of-time AOT compilation engine in Spring Boot 3. If you'd like to learn more, you should check this videos out.

Here's an overview video:

And here's the deep dive into the new Spring Boot 3 AOT engine, making it trivial to build GraalVM native images:

This last video is a deep-dive into the Spring component model and provides an introduction to the new AOT engine, a revision of what it looks like to use some of Spring's rich component model with the new AOT engine, how to migrate existing applications, and then a dissection of the details of the AOT engine and how you can wield it to make troublesome code work in a GraalVM application.

And now, here we are, staring down the holiday season and the new year. I've got many plans for the holiday break, and if I manage to get even 1/10th of it done, then I'll have a lot of good stuff for you next month!

And in the meantime, we have a ton of stuff to review, so let's dive into it!
