Engineering | November 28, 2023 | ...

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. Second, it's my inaugural post as a member of the Broadcom family. Exciting times!

Spring Boot 3.2: A Game Changer

Spring Boot 3.2 is nothing short of revolutionary. I've delved into its myriad features in an in-depth video, which you can watch here. This release includes:

  • reactive cache/scheduled abstraction
  • virtual threads (project Loom)
  • CRaC
  • improved GraalVM native image support
  • Spring for Apache Pulsar support

  • reloadable SSL
  • Java 21
  • observability
  • spring.main.keep-alive=true
  • Docker for Neo4J, ActiveMQ, etc.
  • dependencies updates (of course)
  • TransactionalExecutionListener
