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…

Recap of Part I

In the first part of this blog series, we explored the basics of integrating Spring AI with large language models. We walked through building a custom ChatClient, leveraging Function Calling for dynamic interactions, and refining our prompts to suit the Spring Petclinic use case. By the end, we had a functional AI assistant capable of understanding and processing requests related to our veterinary clinic domain.

Now, in Part II, we’ll go a step further by exploring Retrieval-Augmented Generation (RAG), a technique that enables us to handle large datasets that wouldn’t fit…

Hi, Spring fans! In this installment I talk to Java Developer advocate at Oracle, Billy Korando, about the amazing new features in Java 23 and beyond!

Introduction

In this two-parts blog post, I will discuss the modifications I made to Spring Petclinic to incorporate an AI assistant that allows users to interact with the application using natural language.

Introduction to Spring Petclinic

Spring Petclinic serves as the primary reference application within the Spring ecosystem. According to GitHub, the repository was created on January 9, 2013. Since then, it has become the model application for writing simple, developer-friendly code using Spring Boot. As of this writing, it has garnered over 7,600 stars and 23,000 forks.

The application…

Hi, Spring fans! Welcome to another installment of This Week in Spring! I'm in delightful Dallas, TX, at the amazing JConf.dev show. Then I'm off to Germany, and then back home to do some laundry before heading out to Denver, CO, for the amazing Dev2Next show, before then heading out to Belgium for Devoxx Belgium. It's going to be a fun few weeks. How're you doin'?

• Reload SSL certificates from HashiCorp Vault for Spring Boot
• Huge thanks to Sébastien Deleuze for finding this amazing demonstration from Dr. Fabio Niephaus, which invokes a Rust image processing library that's compiled to WebAssembly from a Spring Boot application running in the JVM using GraalWasm.
• Love to see this: applications are being upgraded to Java 23 left and right!. Have you upgraded yet?
• Speaking of Java 23: it's out! Get the bits now! My favorite installation? sdk install java 23-graalce.
• Did you see the new support in Spring Tools 4 (supporting Visual Studio Code and Eclipse) that offers an inlay hint for query parameters, showing you the name of the method parameter right where you reference it in the query…

I am happy to announce the availability of Spring Modulith 1.3 M3, 1.2.4, and 1.1.9. While the latter two ship the usual bugfixes and service release bugfix upgrades, I am particularly delighted about the milestone releases as it contains two major community contributions. Here are the most significant new features:

• Support for change-aware test execution (contributed by @lukasdo and @davidbilge) which optimizes test runs along the changes made to the application by skipping tests not affected by those.
• A new deleting event publication completion mode to — as the name suggests — immediately delete completed event publications.
• Support for contributing application modules from other packages and external JARs.
• Support for Microsoft SQL Server in JDBC-based event publication registry (contributed by @oyjoh, GH-804).
• Deprecate spring.modulith.republish-outstanding-events-on-restart in favor of the variant residing in spring.modulith.test.… (GH-823…
