The annual SpringOne conference was held online on September 1-2 because of the pandemic. Pivotal, the owner of the Spring project, holds an annual conference to bring together thousands of developers, customers, and partners around the world to exchange practical experiences and discuss technology trends. At the same time, each conference will reveal the next big step of the Spring project. The highlight of this year’s conference was Spring Framework 6.0. Let’s take a look at Spring’s roadmap for some time to come.

Spring Framework 6.0 is getting a lot of attention. It will be based on Java 17 and Jakarta EE 9. Here’s what it looks like now:

Spring 6.0 will be the beginning of Spring’s next decade. What can be revealed so far is:

  • The Spring 6.0 development branch should be finalized by the end of September.
  • A milestone release of Spring 6.0 is available by the end of 2021.
  • The official candidate (RC) version of Spring 6.0 will be released in mid-2022.

Migrate to Jakarta EE 9+

  • jakarta.servlet(Tomcat 10, Jetty 11 related).
  • jakarta.persistence(Hibernate ORM 6?) .

Cloud native

Improved support for GraalVM and Project Leyden, a Java static diagram Project.

Spring Boot 3.0

Spring Boot 3 is definitely based on Spring Framework 6, and Spring Boot 3 will completely open the way to cloud native.

Spring Boot 3 is expected to be released in late Q4 2022.
