Supporting Jakarta EE 10 makes Spring Framework 6 compatible with the latest web servers, such as Tomcat 10.1, Jetty 11, and Undertow 2.3.

'The migration to Jakarta EE has been challenging for us as framework developers', 'the work for observability has also been widespread', and 'the work for Ahead-of-Time (AOT) compilation with GraalVM Native Image has been in the works in some form or another since at least 2019'.įor more insights into the making of these two releases, please see the related interview with Josh Long. In a recent interview, Josh Long, Java Champion and Spring Developer Advocate at VMware, discussing the extended development time for Spring Framework 6, stated: For the first time since 2010, a Spring Framework update followed not one, but two years after the previous major release - version 5.3 in 2020. VMware announced Spring Framework 6 and Spring Boot 3 at its SpringOne 2021 conference. Spring has taken the approach of enabling Spring developers to build on their existing expertise to achieve the benefits of native compilation without significant changes, something unique in the ecosystem. Michael Minella, senior director of software engineering at VMware, told InfoQ: It has built-in support for creating native executables through static Ahead-of-Time (AOT) compilation with GraalVM Native Image. Spring Boot 3 requires Spring Framework 6.

It also embeds observability through Micrometer with tracing and metrics. Spring Framework 6 requires Java 17 and Jakarta EE 9 and is compatible with the recently released Jakarta EE 10. After five years of Spring Framework 5, these releases start a new generation for the Spring ecosystem. VMware released the long-anticipated Spring Framework 6 and Spring Boot 3.
