Spring Modulith 0.1 RC1 released

I am pleased to announce the first and final release candidate of Spring Modulith 0.1. The release primarily is a preparation for the GA one to follow Spring Boot 3.0 GA some time next week. That said, we managed to sneak a couple of improvements into the Application Module Canvas that will surely be helpful. The Canvas now lists Spring bean references into other modules explicitly and thus documents the required interface of the module, just like constructor arguments describe the dependencies of a class.

Spring Framework 6.0 goes GA

Dear Spring community,

It is my pleasure to announce that Spring Framework 6.0.0 is generally available from Maven Central now! This is the start of a new framework generation for 2023 and beyond, embracing current and upcoming innovations in OpenJDK and the Java ecosystem. At the same time, we carefully designed it as a straightforward upgrade from Spring Framework 5.3.x for modern-day runtime environments.

As a major revision of the core framework, Spring Framework 6.0 comes with a Java 17+ baseline and a move to Jakarta EE 9+ (in the jakarta namespace), with a focus on the recently released Jakarta EE 10 APIs such as Servlet 6.0 and JPA 3.1. This provides access to the latest web containers such as Tomcat 10.1 and the latest persistence providers such as Hibernate ORM 6.1. Don’t be stuck on Java EE 8, make the leap to the jakarta namespace, ideally straight to the Jakarta EE 10 level! The upcoming Spring Boot 3.0.0 release includes corresponding managed dependencies for you.

Spring Boot 3.0.0-RC2 available now

On behalf of the team and everyone who has contributed, I’m happy to announce that Spring Boot 3.0.0-RC2 has been released and is now available from https://repo.spring.io/milestone.

This release includes 116 enhancements, documentation improvements, dependency upgrades, and bug fixes.

This is the second release candidate and so doesn’t include much in the way of new features. It does, however, bring a migration to Jakarta EE 10 APIs and a few changes to /actuator endpoints. Our final release is scheduled for November 24, 2022 so this is your last chance to provide feedback or raise issues for any problems that you encounter.

Updates on Spring Cloud Stream 4.0.0 Schema Registry Support

This blog gives an update on the Schema Registry support that is part of Spring Cloud Stream version 4.0.x.

Many enterprises use a schema registry for schema evolution use cases, such as the Confluent Schema Registry. Starting with version 1.1.x of Spring Cloud Stream until 3.0.0, we provided a schema registry server and AVRO-based schema registry client converters that can reconcile the schema from the schema registry server. Spring Cloud Stream version 3.0.0 moved the Schema Registry components into a top-level spring-cloud project, and Spring Cloud Stream included those in its BOM for the end user applications to consume them. However, this didn’t scale well, and with the 3.2 version, we decided to stop having them as part of the Spring Cloud Stream BOM.
