In the rapidly evolving world of artificial intelligence, developers are constantly seeking ways to enhance their AI applications. Spring AI, a Java framework for building AI-powered applications, has introduced a powerful feature: the Spring AI Advisors.

The advisors can supercharge your AI applications, making them more modular, portable and easier to maintain.

If reading the post isn't convenient, you can listen to this experimental podcast, AI-generated from blog's content:

What are Spring AI Advisors?

At their core, Spring AI Advisors are components that intercept and potentially modify the flow of chat-completion requests and responses in your AI applications. The key player in this system is the AroundAdvisor…

Dear Spring community,

Spring Framework 6.2 is shaping up for general availability in November 2024, with particularly significant revisions in the core container and in our web support: see "What's New in Spring Framework 6.2". This release is designed for use with JDK 17-23 and Jakarta EE 9-10.

At the same time, we are planning toward 2025 already, and it is my pleasure to announce that our November 2025 release will be the start of a new major generation: Spring Framework 7.0!

We will upgrade our baseline to Jakarta EE 11 (Tomcat 11, Hibernate ORM 7, Hibernate Validator 9) and embrace the upcoming JDK 25 LTS, while retaining a JDK 17 baseline in alignment with the wider Java ecosystem. For Kotlin applications, we intend to base Spring Framework 7's support on Kotlin 2. Last but not least, our null-safety strategy is converging with the recently released JSpecify…

Upgrading takes time. We understand that. Spring Boot 3 came out in November of 2022 bringing with it a new, modernized baseline of Java 17 and the migration from Java EE to Jakarta EE. It included over 55 managed dependency updates. Native compilation via GraalVM was a first-class option across the portfolio and observability out of the box was a core capability of all Spring projects. However, it wasn't until Spring Boot 3.2 where we began to see that the community's adoption of Spring Boot 3 surpassing that of Spring Boot 2's adoption. Spring Boot 3 has quickly overtaken Spring Boot 2 but…
