It's the end of July! JULY! The seventh month of the year, done and dusted! AHHHHH! I've got memories of being on a tropical beach over the winter holidays, sipping rum and dodging mosquitoes like I was doing a rhythmic gymnastics routine just recently.

I'm happy to announce, that Spring Data JDBC and R2DBC finally support Composite IDs starting with version 4.0.0-M4.

On the Java side these columns get mapped to an entity with an attribute for each column Usage should be straight forward and I'll demonstrate it in the following article for JDBC.

Hi, Spring fans! It's almost SpringOne time!! AAAAH it's all moving so quickly! I can hardly stand it. SpringOne's next month, in lovely Las Vegas, and I'll be there. Will you? Have you registered?

We'll be looking at the impending Spring Boot 4.0 and Spring Framework 7.0 releases! It's going to be a ton of fun. Indeed, you'll notice that's a theme these days: tons of new projects in the milestones or early days stages of development, making their way down the winding road to GA, in time for Spring Boot 4.0 and Spring Framework 7.0. This is my favorite time: we should all be trying the bits…
