Can AI really speed up coding without weakening software quality? In the new episode of The Marco Show, @sdeleuze talks about how Spring AI fits into the Spring ecosystem and why human judgment remains central even as GenAI changes how developers work.

I did a video which I think you might enjoy if you really want to understand how to approach Spring and @SpringBoot, from a very fundamental perspective.
Watch this, understand it, and I promise you'll be MUCH better prepared for working with Spring
Enjoy!

Hi Spring fans! Spring Boot 4.1 is here and with it a ton of amazing features. I'm delighted to have had the opportunity to sit down with Moritz Halbritter, of Spring Boot and Spring Initializr fame, to talk about some of the amazing features.

gRPC in Java used to mean proto files, code gen, build plugins, server wiring, client channels. A lot of busywork before "hello world."
Spring Boot 4.1 fixes most of it. If you can build a REST app, you already know the moves:
→ define the contract
→ drop in a @GrpcService bean
→ inject a stub on the client
Full server, client, and in-memory test, from scratch 👇

Spring Boot 4.1 adds one property:
spring.datasource.connection-fetch=lazy
Your transactional methods grab a connection the moment they open, even when they never run a query. A cache hit, an early return, a slow API call before the save. That connection sits idle. Lazy waits until a statement actually runs.
I built a demo that proves it with HikariCP metrics. Watch the acquire count drop from ~100 to ~0.

You could call tools. You couldn't build on top of tool calling! #SpringAI 2.0 lifts the tool loop out of the chat models and into the advisor chain - composable, observable, replaceable: spring.io/blog/2026/06/15/sp…@SpringAICentral#MCP
AI is transforming open-source security at unprecedented scale. We've reviewed every report and addressed what matters. May's release train moves to June 8–14 — upgrade to the latest Spring patches and stay protected. 🔐spring.io/blog/2026/06/01/sp…
