Hi, Spring fans! How're you doin'? I'm doin' alright! Last week I was in Antwerp, Belgium, for the amazing Devoxx BE show. I did a presentation with my friend and hero James Ward on Spring and Kotlin (that was voted third most-liked talk at a show with more than 250 speakers!) That was a personal career highlight for me - it's not often you get to win and have fun in life. And, as if that wasn't awesome enough, this week I am in Las Vegas, NV, for JavaOne! Fingers crossed, this week will go smoothly, too! Both Devoxx and JavaOne are the first such shows since at least before the pandemic. It's…
Hi, Spring fans! It's Sunday the 16th of October as I write this and I'm winging my way to sunny Las Vegas, Nevada, where I'll be attending (and presenting at) the first JavaOne show in years! It didn't exist as the JavaOne we know and love for years, even before the pandemic interrupted life as we know it worldwide. So this isn't just the first JavaOne since 2019, it's the first JavaOne since 2017! I can't wait to be there, to see the amazing community, to soak up the sun and fun with my teammates and friends in the ecosystem. And we want to see you, too.
There are a few of us doing talks…
Hi, Spring fans! I was just at Devoxx in Belgium, where hundreds of experts from across the Java ecosystem converged for the first time since 2019 to deliver their biggest and best.
I could do a proper trip report, but I really just came here to point you to two talks from two of my amazing teammates, Stéphane Nicoll (@snicoll) and Brian Clozel (@bclozel), who have been very hard at work on both Spring Framework 6 and Spring Boot 3, both of which will land by the end of November, 2022. These are brand new generations of the framework, implying huge new paradigms and new opportunities for…
Hi, Spring fans! In this installment, Josh Long (@starbuxman) looks at the latest and greatest in Spring Boot 3 AOT, then talks to Google's Josh Suereth (@jsuereth) about observability with OpenTelemetry, building better build tools, and so much more.

The Spring Observability Team has been working on adding observability support for Spring Applications for quite some time, and we are pleased to inform you that this feature will be generally available with Spring Framework 6 and Spring Boot 3!
What is observability? In our understanding, it is "how well you can understand the internals of your system by examining its outputs". We believe that the interconnection between metrics, logging, and distributed tracing gives you the ability to reason about the state of your system in order to debug exceptions and latency in your applications. You can watch more about what we think observability is in this episode of Enlightning with Jonatan Ivanov…
Project Loom has made it into the JDK through JEP 425. It’s available since Java 19 in September 2022 as a preview feature. Its goal is to dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications.
This makes lightweight Virtual Threads an exciting approach for application developers and the Spring Framework. Past years indicated a trend towards applications that communicate over the network with each other. Many applications make use of data stores, message brokers, and remote services. I/O-intensive applications are the primary ones that benefit from Virtual Threads if they were built to use blocking I/O facilities such as InputStream and synchronous HTTP, database, and message broker clients. Running such workloads on Virtual Threads…
Hi, Spring fans! Welcome to another installment of This Week in Spring! I write this installment as I pack and prepare for my trip to Antwerp, Belgium, for the always-amazing Devoxx show in Antwerp, Belgium. I've so missed this show over the pandemic and am so looking forward to returning. I hope to catch any and all of you there, too! I'll be copresenting with my pal James Ward about some of the new and novel in Spring Boot 3 and Kotlin. It's going to be awesome - join us and we'll have some fun together!
Now, we've got a ton to cover so let's dive right into it!

Hi, Spring fans! In this installment, Josh Long (@starbuxman) talks to longtime Spring community member and legend Marten Deinum (@mdeinum) about scuba diving, software, Spring, community, and more.
Also: I fixed the odd silence in the middle of the last few episodes! thanks for suffering through it with me. I have no idea what went wrong but I know now how to fix it
