Spring Boot 4's new BeanRegistrar interface finally gives us a clean way to register beans programmatically! No more wrestling with BeanFactoryPostProcessor for dynamic registration. Perfect for conditional loading & performance optimization 🚀 Blog: danvega.dev/blog/programmatic-bean-registration

The Halloween @github.com contribution view is pretty neat :D

A new feature dropped on start.spring.io! Because you all love YAML so much, we've added radio buttons to switch the configuration format from properties to YAML. Hope you brought a ruler and don't live in Norway!

We've published a new installment of our "Road to GA" blog series. This time it's about the huge modularization effort the Spring Boot team has done and which is coming in Spring Boot 4: spring.io/blog/2025/10... #java #spring #springboot

Submit! It’s a great conference, the organizers are absolutely lovely, and speakers are very well treated 😊

Mark your calendars 🗓️ The amazing @garnier.wf joins me on Monday for #SpringOfficeHours at 10:00 AM EDT as we talk about Securing MCP Server with Spring AI www.youtube.com/watch?v=Eh2T...

Uh, today I fell for a phishing email for the first time. Very well crafted, with some info they got from previous leaks, but a slip up on my part. They extracted some personal info but nothing I couldn’t deal with, thankfully. Then they called, v sophisticated too. But I was already aware 😮‍💨

@devoxx.com blues, by @ddoutsiopoulos.bsky.social 🍟

I've done a lot of cleanup on #SpringSecurity MFA support this past week. The updates (along with improved docs) can be seen in the reference docs.spring.io/spring-secur...

YouTube decided to display my leaked passwords as the thumbnail for a … 2h49 video 😱 If you want to learn about authorization, roles and permissions in Spring Security, and optionally steal my very secure passwords, check out my deep dive from @devoxx.com ! youtu.be/LGlyLmxjutI

I love the hallway track at conference! So much joy in meeting with the community ☺️

Who spends time during the break of their 3h deep dive session to bring me a snack?! The Queen of #eatingwhileothersareworking, @alina-yurenko.bsky.social in person. A living example of the Speaker’s Code of Honor. #devoxx @devoxx.com

At the MCP Dev Summit keynote, David Soria Parra (MCP co-creator) called out the MCP Java SDK - "really really popular"! Grateful to be part of it. Shoutout to @thedsp.bsky.social and the #MCP & @spring-ai.bsky.social communities for building something special together! 💚

I was going through some of my favorite shots of @ddoutsiopoulos.bsky.social , and came across this one…

Exciting News! Spring Authorization Server is moving to #SpringSecurity 7.0 spring.io/blog/2025/09...

Spring Boot 4 sera disponible en Novembre prochain. Si vous connaissez un JUG en France ou en Belgique qui serait intéressé par une session, n'hésitez pas à faire signe. RT apprécié :)

Avec les passkeys, on a une authentification sécurisée, pratique et sans mot passe. Découvrez comment les implémenter en pratique avec @garnier.wf ! www.paris-web.fr/202...

You may want to bookmark this "The Road to GA" blog post by @michaelminella.com that we will update every week until end of November with the links to the individual blog posts describing #Spring Boot 4.0 new features. spring.io/blog/2025/09...

Psitt ! Vous venez à Paris Web ? Nous sommes toujours dans l’attente de votre proposition de lightning talk… 😉 www.paris-web.fr/act...

I really liked this presentation about authorization with Spring Security by @garnier.wf at @springio.net. Fantastic followup to last year's session on authentication and protection against common security attacks. #springio www.youtube.com/watch?v=-x8-...

📅 The wait is over: the #Devoxx Belgium 2025 schedule is out! Plan your week, pick your favourites ❤️https://m.devoxx.com/events/dvbe25/schedule

Yay! The recording of my Spring I/O 2025 talk is on! A great sequel to my talk from last year, too :)

First conference rejection of the year! Can't seem to crack that particular nut, I've been trying for 4 years in a row 🤔

On a non-technical note, I've just finished "Redshirts" by John Scalzi, and let me tell you, it's an absolute banger. An exquisite parody, joyful and funny, extremely easy to read, yet surprisingly deep when you stop and think about it. 100% recommend!

If you prefer following the Spring team on BlueSky instead of or in addition to X/Twitter, make sure to follow @spring.io where we start to communicate like we do on SpringCentral.
