Hi, Spring fans! As I write this, I'm winging my way to lovely London, UK, for the amazing Devoxx UK event! I'll be looking at the wide and wonderful world of Springdom. Then, from there, it's off to Code Remix in Miami. I'll also be speaking at the Tampa JUG while I'm there, so look out! After that, I'll be headed back to Europe—a wee bit further north this time—to Stockholm for the amazing JForum event, where I'll be doing a much deeper dive into all things Spring.

You know what I'm most excited about? You don't have to look far to figure it out—just check out the ol' Spring Calendar. Spring…

The Model Context Protocol (MCP) is a powerful feature in Spring AI that enables AI models to access external tools and resources through a standardized interface. One interesting capabilities of MCP is its ability to dynamically update available tools at runtime.

This blog post explores how Spring AI implements dynamic tool updates in MCP, providing flexibility and extensibility to AI-powered applications.

The related example code is available here: Dynamic Tool Update Example

Understanding the Model Context Protocol

Before diving into dynamic tool updates, let's understand what MCP is and…

Hi, Spring fans! In this installment I talk to Mary Ellen Bowman, a legendary Spring instructor!

Hi, Spring fans! In this episode, we catch up with Java Champion, Tessl Devrel head, Virtual JUG co-founder, and friend Simon Maple! This episode was recorded at the amazing ArcOfAI conference held in amazing Austin, TX!

Hi, Spring fans! Welcome to another installment of This Week in Spring, which I'm writing from magnificent Minneapolis, Minnesota, where I'm recording an amazing Frontend Masters course introducing Spring Boot.

• I love this article introducing Spring AI in JavaPro magazine
• Want to run an LLM entirely in Java, supercharged with GraalVM native images? Check out this tweet from GraalVM developer advocate Alina Yurenko — it's dope.
• I loved it so much I made a quick YouTube Short on the same topic.
• By the way, want to learn Java? This is a great resource.
• The amazing Spring AI co-lead Christian Tsolov has a great talk introducing MCP.
• Spring team alumnus Arjen Poutsma has helped shape the APIs in Spring for a long time with his famous Poutsma Principles — in this blog, he discusses them.
• Spring Data 2025.0.0-RC1…

Hi, Spring fans! In this episode I'm joined by well-known member of the Java community Jeff Genender, whose contributions to Apache over the decades have driven several key projects with which you're no doubt familiar.

• Spring AI M7 is here! This new release includes a bunch of awesome new features! And some refactorings. Notably that the Spring AI auto-configuration has changed from a single monolithic artifact to individual auto-configuration artifacts per model, vector store, and other components. This change was made to minimize the impact of different versions of dependent libraries conflicting, such as Google Protocol Buffers, Google RPC, and others. By separating auto-configuration into component-specific artifacts, you can avoid pulling in unnecessary dependencies and reduce the risk of version…

This blog post demonstrates practical implementations of Prompt Engineering techniques using Spring AI.

The examples and patterns in this article are based on the comprehensive Prompt Engineering Guide that covers the theory, principles, and patterns of effective prompt engineering.

The blog shows how to translate those concepts into working Java code using Spring AI's fluent ChatClient API.

For convenience, the examples are structured to follow the same patterns and techniques outlined in the original guide.

The demo source code used in this article is available at: https://github.com/spring…
