I'm excited to share that the there will be support for the OAuth 2.0 Token Exchange Grant (RFC 8693) in Spring Security 6.3, which is available for preview now in the latest milestone (6.3.0-M3). This support provides the ability to use Token Exchange with OAuth2 Client. Similarly, server-side support is also shipping with Spring Authorization Server in 1.3 and is available for preview now in the latest milestone (1.3.0-M3).

OAuth2 Client features of Spring Security allow us to easily make protected resources requests to an API secured with OAuth2 bearer tokens. Similarly, OAuth2 Resource…

Front end development these days is dominated by large JavaScript client side frameworks. There are plenty of good reasons for that, but it can be very inefficient for many use cases, and the framework engineering has become extremely complex. In this article, I want to explore a different approach, one that is more efficient and more flexible, built from smaller building blocks, and well-suited to server side application frameworks like Spring (or similar tools in a range of server side languages). The idea is to embrace the concept of hypermedia, imagine how a next-generation browser would…

Hi, Spring fans! I'm Josh Long, and I work on the Spring team. I'm excited to be keynoting and giving a talk at Microsoft's JDConf this year. I'm a Kotlin GDE and a Java Champion, and I'm of the opinion that there's never been a better time to be a Java and Spring Boot developer. I say that fully aware of where we stand in the span of things today. It's been 21+ years since the earliest releases of the Spring Framework and 11+ years since the earliest releases of Spring Boot. This year marks 20 years…

Hi, Spring fans! In this installment I talk to Cristian Schuszter, a software engineer at CERN. (This episode was recorded live at VOXXED DAYS CERN!).

Don't forget to help us out with the State of Spring Survey

UPDATE: As of March 13, 2024, Mistral AI has integrated support for parallel function calling into their large model, a feature that was absent at the time of this blog's initial publication.

Mistral AI, a leading developer of open-source large language models, unveiled the addition of Function Calling support to its cutting-edge models.

Function Calling is a feature that facilitates the integration of LLM with external tools and APIs. It enables the language model to request the execution of client-side functions, allowing it to access necessary run-time information or perform tasks…

Hi, Spring fans! In this installment, we continue our look at the venerable Spring Authorization Server, this time looking at how to configure persistence and durability for various aspects of the system
