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…

Hi, Spring fans! Last week I was in scintilliating Seoul, Korea, and then tantalizing Tokyo, Japan, and now I'm in marvelous Mumbai, India, at the airport, actually, headed to New Delhi, India. It's been a busy week for me and even busier a week for the community, so let's dive into it!

• Java 23 is here! Happy Java 23 day to those who celebrate! Now to wait for SDKMAN to pick it up...
• In last week's podcast episode, I (finally!) got to sit down with Spring creator Rod Johnson.
• Spring Tools has some cool new upgrades.
• I love this documentary looking at the success of Kotlin.
• Nice tip from Spring community member and JetBrains developer advocate Pasha Finkelshteyn: when you put a cron pattern like * 2 */3 * * 2 inside an @Scheduled annotation in a Spring application, IntelliJ IDEA explains what you just wrote!. Speaking of IntelliJ, the new EAP release is out and has some truly cool AI-centric features…

In this wide-ranging interview, I finally sit down one-on-one and talk to Dr. Rod Johnson, the creator of Spring, entrepreneur, venture capitalist, engineer, father, Kotlin fan, AI researcher, and musician, about this, that, and everything in between, fresh off our recent SpringOne presentation on Spring AI with Spring AI founder Dr. Mark Pollack. This is an extra special, extra-long episode!

Hi, Spring fans! Or, I suppose: 안녕하세요, Spring 팬 여러분! I'm writing this from a café in scintillating Seoul, Korea. It's amazing. I've been talking to developers of all stripes who are using and building upon Spring to do all sorts of cool stuff.

And tomorrow, it's off to jolly Japan. I'll be speaking, among other places, at the Japanese Spring User Group in Tokyo. I'd love to see you there!

We've got a lot to cover so let's dive right into it!
