In a recent research publication: Building effective agents, Anthropic shared valuable insights about building effective Large Language Model (LLM) agents. What makes this research particularly interesting is its emphasis on simplicity and composability over complex frameworks. Let's explore how these principles translate into practical implementations using Spring AI.

While the pattern descriptions and diagrams are sourced from Anthropic's original publication, we'll focus on how to implement these patterns using Spring AI's features for model portability and structured output. We recommend…

TL;DR; The Spring portfolio will begin releasing its milestones and release candidates to Maven Central starting with the releases related to the major versions due out in November.

As we enter the new year, we look forward to many new opportunities for the Spring ecosystem. We see JDK 25 coming in the fall. We see both minor versions of the entire portfolio and a new major version coming out this year with a long list of new capabilities. And we see Spring AI going GA ushering in a new class of workloads for enterprise applications, bringing agentic AI to the enterprise through programming…

On behalf of the team and everyone who has contributed, I’m pleased to announce the availability of 2024.1.2 and 2024.0.8 service releases. These releases ship with dependency upgrades, fixes for regressions and selected improvements.

The upcoming Spring Boot releases will pick up the above releases by next week.

Next week, we are shipping a first milestone of the Spring Data 4.0 development line (Calver 2025.1.0 M1) containing several refinements around JPA support including the baseline upgrade to JPA 3.2 (Hibernate 7.0 Beta3, Eclipselink 5.0 B05) based on Spring Framework 7.0 M1. This is…

The experimental Spring gRPC project released its 0.3.0 version recently. Jars are available in Maven Central, and you can generate a new project with Spring gRPC at https://start.spring.io. We recommend you do that if you are trying it out because there are some build plugins to configure and the generated project will have that all sorted out for you.

The new release has some updates to factory interfaces on the client side. Also there is now full support for autoconfiguration of client side interceptors, including the ones from Micrometer. On the server side we now support Spring Security…

Hi, Spring fans! In this installment I talk to the legendary Dan Haywood, contributor to the Apache Causeway project.

Hi, Spring fans, and greetings from the island of St. Barths! Salut depuis l'île de Saint-Barthélemy!

I'm on a bit of PTO and have been bouncing around from one beach to another with my family. I just landed on a winning combination for a beach: warm water, a restaurant/bar, and some for-pay seats with shade. There are precisely three things to do in such a cherished spot: use it as a launchpad for occasional dips in the sea, read, and sleep—usually in that order!

And you know what I've been reading? The wild and wacky antics of the Spring community, of course!

There's a ton of exciting news…

We're pleased to announce Spring AI MCP 0.5.0 milestone release.
