#jQAssistant 2.9.0 released! - Overriding of rules - Key columns for concepts and constraints - Mark concepts as abstract - Provide Java annotations as separate artifact - Added annotation for TechnicalDebt - Searchable HTML report in a reworked look & feel github.com/jQAssistant#...

Spring Data introduced the awesome AOT compiled repositories feature in their 2025.1 release, and the @springtools.bsky.social 5 release takes full advantage of that, bringing insights right into the editor, incl. generated query statements, jump the implementation, and more... 😎

DDD – Demo-Driven Development.

I really, really like Alistair's pragmatic presentation on Hexagonal Architecture. 4m30s – everything that makes up its core in one slide: interfaces to separate technical code from business logic, connected via dependency injection. 1/5

I just fixed the "floppy disk drive" ticket in Spring Modulith. 🙂 github.com/spring-proje... #Commodore1541

Hallo Freund:innen des gepflegten #Java-Backends! 👋 Am 12.2. berichte ich bei der Java User Group Hamburg über #Spring Modulith. 👉 nilshartmann.net/t/e... #Java-Backends!#Springicht von der Warteliste abschrecken lassen...)

🥁📢 Spring Modulith 2.1 M1, 2.0.2, and 1.4.7. The milestone upgrades to Boot 4.1 M1 and adds support to reset the time machine and to skip all tests in case our JUnit integration detects no changes to the project. Grab it while it's 🔥! 🍃📦 #SpringModulith

Today marks the 30th anniversary of #Java 1.0! Happy Birthday! 🥳🎂☕️🫶

A Structurizr MCP server is available on GitHub! It provides an easy way to load workspaces from the local file system (JSON or DSL) and to load JSON workspaces from a self-hosted Structurizr server. Link: github.com/structurizr/...

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring Boot 3.5.10 has been released and is now available from Maven Central. spring.io/blog/2026/01... @spring.io #spring #springboot #java

I'm so glad #GitHub finally moved to a <div /> soup to make what's previously been a boring-looking <table />, much more “dynamic.” 🙄

With the release of version 0.13.0, NullAway’s support for JSpecify continues to improve. A huge thank you to Manu Sridharan and all the contributors involved! github.com/uber/NullAwa... #java #spring

I want a "open all files change in the latest commit" feature in my IDE.

Spring Data 2025.1.2 & 2025.0.8 released spring.io/blog/2026/01...

Today marks the 18th anniversary of the first commit of what should eventually become Spring Data JPA. What a ride! 🥳🍃🛢️ github.com/synyx/hades/... #SpringData #JPA #Synyx

That’s a frickin‘ insane lineup. Sheeran, Mayer, Palladino, Grohl, Slatkin. And a riff RATM could’ve come up with. 🤯 #Drive

I constantly hear people excited about #IDEA and how productive they are with it. But why on earth do I constantly run into some of the most fundamental things, like the build not working every time I try it? – youtrack.jetbrains.com/issue/IDEA-3... – youtrack.jetbrains.com/issue/IDEA-3...

I'll be giving a “Tactical Domain-Driven Design with Java and Spring” workshop at Voxxed Days Ticino this year. Be sure to sign up if you're in the area! ☕️⚗️🍃 - Workshop – vdt26.voxxeddays.ch/talk/?id=5439 - Workshop tickets – vdt26.voxxeddays.ch/workshops/ #Java #Spring #DDD

🍃 With #SpringFramework 7.0.3, you'll be able to globally disable test ApplicationContext pausing (in case pausing causes issues for you) by setting the "spring.test.context.cache.pause" property to "never". github.com/spring-proje...

Expectedly brilliant interview with @karenhao.bsky.social about the problems and not so obvious personal and economic drivers behind the state-of-the-art #AI.

⏰ Tomorrow is the LAST DAY to submit your session for Spring I/O 2026. If you've been thinking about submitting, this is your sign, do it now! Don’t let the "I'll do it later" turn into "maybe next year".

Let me introduce you to another new validation in the Spring Tools: it reminds you that you should not try to define the path in the controller annotation itself - and as a bonus, comes with the corresponding quick fix 🥳

#JUnit 6.0.2 is released! 🐞 Bug fixes and enhancements since 6.0.1 docs.junit.org/6.0.2/releas...

Proof is overrated. This is a brilliant talk by Rory Sutherland: [youtu.be/lhlS-Wds02M...] where he makes two essential points. First, it's a huge problem when "rational" people get veto power over creative, innovative, "irrational" people. 1/11

🎉 New year, new goals, and last chance to submit your proposal! 🎤 Only 4 days left to submit your session ⏰ Kick off 2026 by sharing your ideas, lessons, and passion with the community.
