We're excited to introduce Spring AI MCP, a robust Java SDK implementation of the Model Context Protocol (MCP). This new addition to the Spring AI ecosystem brings standardized AI model integration capabilities to the Java platform.

What is MCP?

The Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to Large Language Models (LLMs). MCP provides a standardized way to connect AI models to different data sources and tools, making integration seamless and consistent. It helps you build agents and complex workflows on top of LLMs. LLMs frequently…

The Amazon Bedrock Nova models represent a new generation of foundation models supporting a broad range of use cases, from text and image understanding to video-to-text analysis.

With the Spring AI Bedrock Converse API integration, developers can seamlessly connect to these advanced Nova models and build sophisticated conversational applications with minimal effort.

This blog post introduces the key features of Amazon Nova models, demonstrates their integration with Spring AI's Bedrock Converse API, and provides practical examples for text, image, video, document processing, and function…

OpenAI provides specialized models for speech-to-text and text-to-speech conversion, recognized for their performance and cost-efficiency. Spring AI integrates these capabilities via Voice-to-Text and Text-to-Speech (TTS).

The new Audio Generation feature (gpt-4o-audio-preview) goes further, enabling mixed input and output modalities. Audio inputs can contain richer data than text alone. Audio can convey nuanced information like tone and inflection, and together with the audio outputs it enables asynchronous speech-to-speech interactions. Additionally, this new multimodality opens up possibilities for innovative applications, such as structured data extraction. Developers can extract structured information not just from simple text, but also from images and audio, building complex, structured objects…

Since its inception, Spring Data Repositories have been designed for extension, whether you want to customize a single query method or provide a completely new base implementation.

The 2024.1 release enhances your ability to extend a repository with custom functionality making it easier than ever for anyone to create extensions that can be shared across different projects.

Let’s explore an example to see how this works in practice.

Imagine you are using MongoDB as a document store to manage a movie database. You want to leverage MongoDBs Atlas vector search functionality through your…

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's the first week of December and I am in the amazing city of Perth, Australia. Perth, for those of you who don't know, is amazing. And well worth the journey. But it is quite the journey! 27 hours, door-to-door, from San Francisco to Perth! Insanity.

I'm super happy to be here, though, talking to amazing folks before I begin my journey from Melbourne, Brisbane, and Sydney, Australia for the epic YOW! conference. It's going to be a ton of fun.

• I love this InfoQ interview with Spring Framework lead Jürgen Hoeller and Spring Framework contributor Sébastien Deleuze
• I also love this article on reactive websockets with Spring
• Extending Spring Data repositories just got easier!
• Huh. Apparently the old SpringSource repositories just got sunsetted. I had no idea we still maintained them.
• In this week's installment of A Bootiful Podcast, I talk to Dave Cramer, PostgreSQL and PostgreSQL JDBC driver contributor extraordinairre
• Spring Cloud 2023.0.4 is now available
• Spring Cloud Stream Applications is now available
• HTTP3 in Reactor!

Hi, Spring fans! Happy Thanksgiving to my American listeners! and happy Thursday to the everyone! In today's episode I talk to PostgreSQL and PostgreSQL JDBC contributor Dave Cramer. #postgresql #jdbc #sql #java

HTTP/3, the latest major version of the Hypertext Transfer Protocol, had its specification finalized in June 2022. This version is designed to enhance performance, reliability, and security. Unlike its predecessors, HTTP/3 utilizes QUIC instead of TCP as its transport layer. QUIC is a UDP-based, multiplexed, and secure transport protocol that includes built-in TLS 1.3 encryption, making QUIC encrypted by default.

To learn more about the performance and benefits of HTTP/3, check out What is HTTP/3.

For information on browser adoption, take a look at Examining HTTP/3 Usage, which also provides raw data on HTTP versions used by…
