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.

Hi, Spring fans! In this installment we talk to Wiremock's leaders Lee Turner and Tom Akehurst

Hi, Spring fans! How are ya? I'm doing fine. Excited, even. You see, Spring AI M7 is coming soon! In theory, it drops on Thursday. Don't hold us to that — these things can change :-) But soon, and it's turning out to be a whopper of a release!

You should try upgrading your application to the new M7 by using the -SNAPSHOT builds. The coordinates for the various starters have been reworked, so things will break there. Don't panic — you just need to update the coordinates. There's good information in the documentation.

Here's the gist:

• Model starters: spring-ai-{model}-spring-boot-starter → spring-ai-starter-model-{model}
• Vector Store starters: spring-ai-{store}-store-spring-boot-starter → spring-ai-starter-vector-store-{store}
• MCP starters: spring-ai-mcp-{type}-spring-boot-starter → spring-ai-starter-mcp-{type}

Hi, Spring fans! In this installment I talk to AWS Developer Advocate and industry legend James Ward about AWS Bedrock, Amazon Cohere, Spring AI, MCP, and so much more!

Using Spring AI 1.0.0-SNAPSHOT: Part 2 - Important Changes and Updates

This blog post is a continuation of our previous article Using Spring AI 1.0.0-SNAPSHOT: Important Changes and Updates, where we introduced the significant changes to artifact IDs, dependency management, and autoconfiguration in Spring AI 1.0.0-SNAPSHOT.

Since publishing that article, the Spring team has released an updates to the snapshots, In this follow-up article, we'll explore the latest changes and provide additional guidance for developers working with the snapshot versions. For comprehensive details, refer to the Spring AI Upgrade Notes…

Spring AI offers support for Model Context Protocol, or MCP for short, which allows AI models to interact with and access external tools and resources in a structured way. With Spring AI, developers can create their own MCP Servers and expose capabilities to AI models in just a few lines of code.

Authorization and security in MCP

MCP Servers can run locally, using the STDIO transport. To expose an MCP server to the outside world, it must expose a few standard HTTP endpoints. While MCP Servers used privately might not require strict authentication, enterprise deployments need robust security and permission management for exposed endpoints. This challenge is addressed in the newest version of the MCP specification (2025-03-26), which was released last week. It lays the foundation for securing communications between Clients and Servers, leveraging the widespread OAuth2 framework…

Hi, Spring fans! Welcome to another exciting installment of This Week in Spring! It's April Fools day, so be wary of things you read on the internet, but it's also the 11th anniversary of Spring Boot 1.0, which was released this day in 2014! (that's not an April Fools). Happy birthday!

I'm in excellent Austin, TX, at Dr. Venkat Subramaniam's phenomenal Arc of AI show. I love this show! So many amazing people - many of whom also happen to be world-class speakers and engineers - converge in one place to synthesize their vantage point on "A.I." in one hour. Of course, I will be talking about…

Salut fans de Spring! In this installment I'm joined by the legendary Anthony Dahanne. If you've enjoyed success in production using Spring's built-in spring-boot:build-image capability, you've got today's guest Anthony to thank for it!

Using Spring AI 1.0.0-SNAPSHOT: Important Changes and Updates

Spring AI 1.0.0-SNAPSHOT introduces several important changes to artifact IDs, dependency management, and autoconfiguration. This blog post outlines these changes and provides guidance on how to update your projects.

The most significant change is the naming pattern for Spring AI starter artifacts:

• Model starters: spring-ai-{model}-spring-boot-starter → spring-ai-starter-model-{model}
• Vector Store starters: spring-ai-{store}-store-spring-boot-starter → spring-ai-starter-vector-store-{store}
• MCP starters: spring-ai-mcp-{type}-spring-boot-starter → spring-ai-starter-mcp-{type}
