The Spring team will be rolling out a simplified contribution process that replaces the requirement to sign a Contributor License Agreement (CLA) with a Developer Certificate of Origin (DCO). The process will start this week with Spring Framework, Spring Security, & Spring Boot and then roll out to the entire Spring portfolio.

History

Spring has long used a permissive Contributor License Agreement (CLA) in order to provide legal protections to the Spring project, users, and the Spring team. Long time contributors may remember that signing the CLA originally involved emailing a signed PDF of…

Hi, Spring fans! Happy happy = new Year(2025)! It's a new year and a new opportunity! In this episode I talk to my friend and legendary technologist Dez Blanchfield!

Hi Spring fans! Happy New Year! And welcome to another installment of This Year in Spring!

The year that was...

I write this edition from a desk overlooking the beautiful jungle of Martinique, a beautiful island nation in the French Caribbean. I’m sipping some rhum martinique, enjoying the semi-sweltering heat, and thinking about the year that's been 2024. Every year at this time, since 2011, I write this year in spring, an abbreviated look at the year from the rearview mirror.

So many amazing things happened this year. It’s sort of difficult to put my finger on any one thing. But, I shall try…

Hi, Spring fans! (and happy holidays!) in this installment I talk to Intact's Luke Shannon about their use of Spring, developer portals, and so much more.

Hi, Spring fans! Welcome to another installment of a Bootiful Podcast! It's the 17th of December, 2024! And you know what means? The end of the year is nearly upon us! I can't believe it. It's been a very long year indeed, but I'm happy to get on board a flight bound for San Francisco soon and wind down my year in the company of friends and family. I hope you will too. Let's dive right into this week's roundup!

• A nice blog by Michael Minella: Spring Support Updates
• this is an interesting comparison of performance and efficiency in a Spring application implemented using the reactive system and a Spring application implemented without reactive, and - importantly - without Java 21's virtual threads…

Hi, Spring fans! In today's installment I talk to industry legend K. Siva Prasad Reddy (@sivalabs). You've probably read one of his blogs. I know I have!

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…
