Reactor Kafka Project Will Be Discontinued

TL;DR: We’ve decided to discontinue future maintenance of the Reactor Kafka project and deprecate its associated components within the Spring portfolio.

Hi, Spring fans! Welcome to another installment of This Week in Spring! As I write this, I'm in sunny Stockholm, Sweden for the JForum #123 installment. This is, apparently, the first time the meetup is completely full up since before the pandemic, with more than 150 people in attendance! Tak, Stockholm!

Then, tomorrow, I'm off to beautiful Barcelona, Spain, for the amazing Spring I/O event. I'll be doing part of the keynote with Spring AI founder Dr. Mark Pollack; I'll be looking at Spring's rich integration with AOT and GraalVM with GraalVM founder Thomas Wuerthinger; and I'll be doing…

Your First Spring AI 1.0 Application

by Dr. Mark Pollack, Christian Tsolov, and Josh Long

Hi, Spring fans! Spring AI is live on the Spring Initializr and everywhere fine bytes might be had. Ask your doctor if AI is right for you! It's an amazing time to be a Java and Spring developer. There's never been a better time to be a Java and Spring developer, and this is doubly true in this unique AI moment. You see, 90% of what people talk about when they talk about AI engineering is just integration with models, most of which have HTTP APIs.
