Hi, Spring fans! How are you? Can you believe we're already staring at the end of the month? It's that time of the year when we see new releases, and the new releases reflect that frenzy! Soon: Spring Boot 3.4.0! Are you updated? Make sure you're updated!

Remember: Spring projects leave open source support after a year. So, roughly, when Spring Boot 3.4.0 drops, Spring Boot 3.2.0 and earlier won't be supported anymore. If you want to know where you stand, check the support windows on the various projects' pages

• Spring Framework 6.2.0 available now! This foundational piece kicks off our release cycle for the season. Remember: we do new releases of Spring Framework and Spring Boot every six months! Spring Framework 6.2 brings new baseline dependencies, removed APIs, tweaked Priority behavior in the core container, deeper generic type matching, @Fallback beans, SpEL updates, smarter resource loading in web…

Why Spring AI: The Seamless Path for Spring Developers to the World of Generative AI

Intro

As a Java developer exploring the world of generative AI, you’re probably aware of several frameworks that promise to make AI integration easy. I believe Spring AI stands out as the natural choice, especially for developers already working within the Spring ecosystem. Built on the same foundation as Spring Boot and Spring Data, Spring AI makes adding AI capabilities to your applications seamless and intuitive, without requiring you to learn an entirely new set of paradigms.

Seamless Integration with the…

Hi, Spring fans, JVM enjoyers, and cloud natives! Have I got a treat for you today! We're going to be talking to my longtime pal Ken Sipe. #groovy #java #kotlin #go #rust #spring #jvm

Hi, Spring fans! Welcome to another installment of This Week in Spring!

• Modern Java is amazing
• I'll be speaking at VOXXED Days Amsterdam next year. Will you be there?
• this French language post on how to integrate Langchain4J with Spring is pretty amazing
• the latest Pkl release …

Hi, Spring fans! In this installment, I talk to legendary Gradle Developer Productivity Engineering guru (formerly of JFrog) and hero to the JVM-language community, Baruch Sadogursky, recorded live from Dr. Venkat Subramaniam's amazing conference, Dev2Next 2024!

This Week in Spring - November 5th, 2024

Hi, Spring fans! Welcome to another installment of This Week in Spring! It's the 5th of November, 2024, and, um, I - an American - am desperately trying to keep calm and carry on. I did everything I can do (VOTE!), and so it's with considerable enthusiasm that I dive into this week's (hopefully distracting) roundup!

• Dr. David Syer announcing the Spring GRPC project
• a Spring Boot and GraalVM native image application, demonstrated by awesome Oracle GraalVM developer advocate Alina Yurenko
• understanding the Spring Boot @SpringBootApplication annotation
• understanding the lifecycle of a Spring Boot application
• there's never been a better time to be a Java and Spring developer!
• A New Developer's Journey, in 2024
• Super cool! Java 24 is targeting a fix to allow developers to synchronize code on virtual threads and avoid pinning

Hi, Spring fans! How're things? It's almost Halloween! I'm so excited! I'm going as a PHP program. Boooooooo...t. I'm writing this from the amazing Vaadin Create conference in Frankfurt, Germany, about to do my keynote for an amazing, Spring-loving audience here. So, without further ado, let's dive right into it!

• RestClient support for OAuth 2 in Spring Security 6.4
• Spring Modulith 1.3 RC1, 1.2.5, and 1.1.10 released. The RC has several cool new contributions, including one from my friend and teammate Cora Iberkleid introducing an archiving event publication completionm mode; and one contribution from me, that supports externalizing events with Spring Integration MessageChannels. Nice! Get the bits now!
• An awesome blog from Marcin Grzejszczak: Let's Use OpenTelemetry with Spring
• Spring Boot 3.4.0 RC1 is available now
• in last week's A Bootiful Podcast, I talked to GraalVM benevolent dictator …

In Spring Security 6.2 and 6.3, we have worked to steadily improve configuration for applications using OAuth2 Client. Configuration for common use cases has been simplified by allowing applications to publish beans which are automatically included in the overall OAuth2 Client configuration during application startup. Recent improvements include:

• Extension grant types can be enabled simply by publishing a bean of type OAuth2AuthorizedClientProvider (or ReactiveOAuth2AuthorizedClientProvider)
• OAuth 2.0 Access Token Requests can be extended with custom parameters simply by publishing one or more beans of type OAuth2AccessTokenResponseClient (or ReactiveOAuth2AccessTokenResponseClient)
• Spring Security automatically publishes a bean of type OAuth2AuthorizedClientManager (or ReactiveOAuth2AuthorizedClientManager) if one is not already published, requiring less boilerplate configuration when an application needs to obtain access tokens

Introduction

In the dynamic realm of observability, OpenTelemetry is a new set of tools that emerged from the now-deprecated OpenCensus and OpenTracing projects. When it comes to Spring Framework, Spring Boot, Spring Data, and Spring Cloud observability, mature solutions like Micrometer, the de facto Java standard of observability, are being used to instrument their various modules. The OpenTelemetry project consists of many components. The one we find most compelling is the OpenTelemetry Protocol (OTLP), which allows developers to harness the power of a consistent telemetry format for any…
