Hi, Spring fans! Welcome to another installment of This Week in Spring! It's been a busy week indeed since we last spoke! Last week I was in Amsterdam for the IntelliJ IDEA conference and for the JSpring event in Utrecht. Now, I'm in Tokyo, Japan, for the JJUG Spring 2025 event. Importantly: both of these are Java events that take place on or around the spring season in the northern hemisphere, and are not (just?) about Spring Framework. Funnily enough, though, I did get a kick out of seeing this article of Spring creator Rod Johnson presenting at JSpring in Utrecth 20 years ago!. The more…

Hi, Spring fans! In this installment I talk to IntelliJ IDEA lead Aleksey Stukalov

Hi, Spring fans! Welcome to another installment of This Week in Spring! I just finished recording my session with IntelliJ IDEA project lead Aleksey Stukalov about all the amazing features coming to IntelliJ IDEA to better support Java, Kotlin, and Spring developers.

It went off without a hitch (even though we're using a few early features), and I want to thank the Jetbrains team for the chance to participate.

Tomorrow, I speak at the amazing JSpring conference (sibling conference to the amazing JFall conference), too.

Hi, Spring fans! In this installment we talk to the legendary Victor Rentea. This episode was recorded live at Devoxx UK 2025.

Hi, Spring fans! Welcome to another installment of This Week in Spring! This time, I'm talking to you after an insane week behind me. Last week I flew from San Francisco to Stockholm, Sweden where I was the speaker for the JForum event, a monthly meetup. Spring drew the largest audience to JForum since before the pandemic! Then, it was off to beautiful Barcelona for the fantastic Spring I/O event, where I did a keynote with Dr Mark Pollack on Spring AI, then hosted a joint talk with Spring cofounders Rod Johnson and Juergen Hoeller. Then, I did a joint talk with GraalVM found and Oracle vice…

The emergence of Large Language Models (LLM) has propelled Generative AI and surfaced one of its key components to a broad audience: Embeddings.

Embeddings are a vector representation of data in a high-dimensional space capturing their semantic meaning. Vector representations allow for more efficient and effective search (Vector Search) of similar items. Vector search is typically used to build Retrieval-augmented generation (RAG) systems and so there is demand for vector databases.

While new vector databases are on the rise, existing database engines are gradually incorporating vector search…

Hi, Spring and Spring I/O fans! In this installment we have the privilege of chatting with friend of the community and legend Sergi Almar about the amazing Spring IO 2025, where this episode was published, and a lot more.

In the past couple of years we have seen heavy investment throughout the Java ecosystem to reduce application startup times. The main focus gravitates around Ahead-of-Time optimizations. May it be condensing code into a GraalVM native executable, capturing already optimized bytecode with Coordinated Restore at Checkpoint (CRaC), Class Data Sharing (CDS) or its more recent successor AOT cache (part of project Leyden). While barriers to entry vary between the different approaches, all of them move performance optimizations away from runtime into an earlier phase, such as build time or a separate…

Hi, Spring fans! Welcome to another installment of This Week in Spring! As I write this, I'm in sunny Stockholm, Sweden for the JForum #123 installment. This is, apparently, the first time the meetup is completely full up since before the pandemic, with more than 150 people in attendance! Tak, Stockholm!

Then, tomorrow, I'm off to beautiful Barcelona, Spain, for the amazing Spring I/O event. I'll be doing part of the keynote with Spring AI founder Dr. Mark Pollack; I'll be looking at Spring's rich integration with AOT and GraalVM with GraalVM founder Thomas Wuerthinger; and I'll be doing…
