Spring Framework 6.0 RC1 Released: Key Features and Changes

Hello everyone, I'm Chen (intro).

Spring Framework 6.0 released its first RC version.

The release notes state that Spring Framework 6.0 is a major update, and RC1 requires Java 17 or higher , and has migrated to Jakarta EE 9+ (using the jakarta namespace instead of the previous javax -based EE API), along with other infrastructure changes.

Based on these changes, Spring Framework 6.0 supports the latest web containers such as Tomcat 10 / Jetty 11, and the latest persistence framework Hibernate ORM 6.1. These features are only available for the jakarta namespace variants of the Servlet API and JPA.

A major change in this version is the completion of AOT compilation for the Spring application context and corresponding AOT processing support, which helps optimize deployment, from fine‑tuned JVM deployments to first‑class support for GraalVM native images.

It is worth noting that developers can now experience virtual threads (preview in JDK 19's Project Loom) in Spring‑based applications, with a new option to plug in an Executor based on virtual threads, aiming to provide first‑class configuration when Project Loom becomes generally available.

In addition to the above changes, Spring Framework 6.0 also includes many other improvements and features, such as:

Providing an HTTP client interface based on @HttpExchange

Support for RFC 7807 problem details

Spring HTTP client offers Micrometer‑based observability

…

Additionally, the team says they will release the first RC of Spring Boot 3.0 next week, the second RC of Spring Framework 6.0, and the GA in November.
