🎾 Nice combo for 2026!
Spring I/O 2026 will take place the same week as the Barcelona Open Banc Sabadell, one of my favourite weeks of the year as a tennis lover. I never miss the tournament!
If you join Spring I/O, you can also catch some world-class tennis right next door.

Still on Java 17 and planning to upgrade?
☕️ Skip 21 and go straight to 25.
Java 25 provides memory efficiency gains and garbage collection improvements with zero code changes. Align it with your Spring Framework 7 / Spring Boot 4 upgrade.
Strong recommendation by Juergen Hoeller.

Who else remembers going to the store to buy Spring Framework 1.0 on floppy disks with a 500-page manual? 😅
Ok, not really for Spring…But Spring Framework 7.0.0-M9 (last milestone) is out 🎉 no store trip needed, just update your dependencies and give it a spin.

The Spring Debugger from @intellijidea.com autodetects your datasources and registers them into the Database tool window. This is particularly helpful when testing with Testcontainers.
It gives you instant database inspection, no setup. Super handy. 🧐

I’m still surprised by how much XML shows up in the Spring Framework docs in 2025.
For newcomers, it might look like XML is the recommended approach, but annotation-based and Java-based configuration have been the norm for years. Heard it many times in my trainings.

Continuing with the Spring optimization journey,
Spring Data 4.0 goes full speed ahead with AOT repositories 🚀.
Now your repository query methods are converted to actual source code at build time and compiled together with your application.

Over 80% of YC S25 startups are AI companies 🤯
I’m glad frameworks like Spring AI exist, making it possible to build AI applications without leaving the JVM. That lowers the barrier for thousands of Java/Spring developers to join this wave.

My Spring Boot apps expose plenty of metrics through Micrometer + Prometheus, but I'm really bad at creating Grafana dashboards.📈
I’ve been experimenting with the MCP server for Grafana and now instead of hand-crafting dashboards, I just ask: "Generate an HTTP dashboard for me":

🚀 Your Spring app could start up way faster.
With AOT Cache (introduced in Java 24) + Spring AOT, startup times drop like magic.
Curious how much you can gain? 👇

The next few months are going to be very interesting for Java / Spring devs. Java 25 is just 19 days away and can't wait to upgrade.
I know some of you might still be on Java 8, but remember, as @starbuxman.joshlong.com says, Java 25 will be +3x better than Java 8!

Just received a message that made my day.
I've been teaching Spring for the last +16 years and welcoming newcomers to the Spring ecosystem. This kind of feedback means a lot 💚.

📍Next year, we’re moving to a new venue. I’ll miss the place we’ve called home since 2018, but change brings fresh energy!
Spring I/O 2026 (13-15 April) is already taking shape, and I can’t wait to see you there. #springio26

It usually takes me a week to decompress after @springio.net, maybe more as I get older 😅.
Spring I/O has exceeded my expectations one more year. Every session, every hallway chat, every spontaneous moment reminded me why this community is so special.
