Welcome to this repository!

If you're into Spring Boot, you're in good hands: this repository highlights some of the new features available starting Spring Boot 3.0.

In a nutshell, this version brings in these new features:

Spring Framework 6.0: the next big thing in the Spring success story, Java 17 is now the base version
GraalVM support: native image as a first-class citizen in the Spring ecosystem, compile your Java app as a native process with a lower memory footprint and a faster startup
better support for OpenTelemetry: Spring Boot provides the latest version of Micrometer, a vendor-neutral application metrics facade which allows you to leverage OpenTelemetry to plug in your favorite observability tools
the move to Jakarta API: no more javax.* packages, it's time to move to the next version of Java EE, aka Jakarta with jakarta.* packages
and more...

Check out this video from Josh Long to learn more about Spring Boot 3.0 and Spring Framework 6.0:

This repository is splitted in modules:
