There's a new release of the amazing—if experimental—Spring gRPC project: version 0.4.0. I won't get into the nitty-gritty of all that's new, but I just wanted to highlight how elated I am to use it and walk you through the step-by-step path to gRPC joy. A million little things fall into place to make it the smoothest experience I've ever had using gRPC!

I went to the Spring Initializr and selected GRPC, GraalVM, and Web. I'm a Maven enjoyer, but you do you. I chose Java 23, 'natch, since Java 24 is coming in a week or two. I figured this…

Hi, Spring fans! Welcome to another installment of This Week in Spring, and Happy Devnexus 2025 to those who celebrate! That's right sports fans, I'm off to awesome Atlanta, Georgia later today for Devnexus, one of the world's largest annual gatherings of Java community and luminaries alike. I'll be doing a talk on the latest-and-greatest in Spring Boot as well as another talk looking at Spring AI with the legendary Dr. Mark Pollack, founder of Spring AI. And, of course, I'll be soaking up all the other talks by Spring luminaries like Glenn Renfro, Jonatan Ivanov, Ken Kousen, Ryan Baxter…

I am happy to announce the availability of Spring Modulith 1.4 M2, 1.3.3, and 1.2.9. While the latter contain a few bug fixes and the usual dependency upgrades to the latest Spring Boot releases, the milestone release ships a couple of important new features.

• The observability module now automatically creates counters for application events published by modules. A new ModulithEventMetrics API has been introduced and can be used through ModulithEventMetricsCustomizer beans registered in the ApplicationContext (GH-1068).
• The runtime support has been revamped to avoid the dependency on an external library to topologically sort application modules, so that they can be traversed in dependency order (GH-1060). This allows assuming a stable module order in the application metadata file that – previously only created in AOT mode – is now also written when generating documentation (GH-1063). That in turn allows us to avoid the full bootstrap of an ApplicationModules instance at runtime, for example, to execute ApplicationModuleListener beans (GH-1062, GH-1065…
