CDS with Spring Framework 6.1

Engineering | Sébastien Deleuze | December 04, 2023 | ...

As a follow-up to the Runtime efficiency with Spring blog post, I am happy to share that our exploration of Project Leyden optimizations has led to some interesting discoveries regarding the JDK's little-used CDS ("Class Data Sharing") feature and has materialized into a new feature that we have been able to ship in Spring Framework 6.1.

Hi, Spring fans! I hope everyone who celebrated Thanksgiving had a wonderful time. Did you indulge in too much turkey? Anyway, let's jump into this week's edition of This Week in Spring—a particularly special one for a couple of reasons. First, it's our first issue after the launch of Spring Boot 3.2 last Thursday.

Spring Modulith 1.1 GA and 1.0.3 released

Releases | Oliver Drotbohm | November 24, 2023 | ...

On behalf of the community I am delighted to announce the general availability of Spring Modulith 1.1 and the 1.0.3 bugfix release. This rather short stint after our 1.0 GA release in just three months ago brings us back in sync with the Spring Boot release train which we are going to follow going forward. We still managed to package up quite a few great new features, most notably:

  • Support for event externalization into AMQP, Kafka, JMS, AWS SNS and SQS (the latter two contributed by Maciej Walkowiak) #248 #344
  • API to deal with completed and incompleted event publications #294
  • Strengthened relationship constraints for code residing in the application root #317
  • A Now interface extracted from Moments and additional methods to access today (LocalDate) and the current point in time as Instant.
  • @ApplicationModuleListener moved into the events package (in the …-events-api artifact) #322
  • Support for the actuators in native images #376, #375
  • A Neo4j implementation of the Event Publication Repository (contributed by Gerrit Meier)
