Hot on the heels of Spring Boot 3.0 GA, it's my pleasure to announce the availability of Spring Modulith 0.1. The release concludes the integration of the Moduliths project into the Spring ecosystem. I want to especially thank Dmitry Belyaev and Björn Kieling who helped a lot during the migration and contributed significant new features to the project, the event publication repository implementations for JDBC and MongoDB in particular.

For a general introduction into the project, please check out the original announcement and this InfoQ article.

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.

Also, the Canvas now includes value types exposed by a module. These types are identified by either the annotations or interfaces provided by the jMolecules DDD library…

I am pleased to announce the availability of the second milestone of Spring Modulith 0.1. The release contains a few minor bug fixes and a couple of community contributions to the reference documentation. Find a complete overview about the changes included in the release here. For a general introduction into the project, please consult the announcing blog post.

The current plan is to ship an 0.1 RC1 after Spring Boot’s second RC, followed by a GA version on the heels of Boot’s GA.

When designing software systems, architects and developers have plenty of architectural options to choose from. Microservice-based systems have become ubiquitous in the last couple of years. However, the idea of monolithic, modular systems has also regained popularity recently. Independent of the architectural style ultimately selected, the individual applications comprising the overall system need their structure to be evolvable and able to follow changes in business requirements.

Traditionally, application frameworks have provided structural guidance by providing abstractions aligned with technical concepts, such as Spring Framework’s stereotype annotations (@Controller, @Service, @Repository, and so on). However, shifting the focus to align code structure with the domain has proven to lead to better structured applications that are ultimately more understandable and…

Updates

• [09-19] Vulnerability announced here and Spring Data REST 3.6.7 and 3.7.3 released
• [09-19] Blog post updated to refer to the CVE report published

The Spring Data 2021.1.7 and 2021.2.3 releases shipped on September 19th contained releases for Spring Data REST 3.6.7 and 3.7.3 which include fixes for CVE-2022-31679. Users are encouraged to update as soon as possible.

I am excited to announce that Spring HATEOAS 1.4 GA has been part of the cascade of releases that lead to the Spring Boot 2.6 last week. The release ships a couple of new features and all bug fixes we have incorporated in the 1.3.x line. The most notable new features are:

• Full support for level 4 URI templates

• Support for non-composite request parameter rendering

• Improved HAL-FORMS support (additional property constraints, custom media types)

• Additional HTML input types (checkbox, radio, file)

• General dependency upgrades, including Spring Framework 5.3.13 and Jackson 2.13.9.

Find more detailed information about all changes made in the 1.4 line in the release’s change log. The release was included in the Spring Boot 2.6 release announced last week…

On behalf of the Spring community I’d like to announce the availability of Spring HATEOAS 1.2.6 and 1.3.1. The releases contain general bugfixes and are scheduled for inclusion in the upcoming Spring Boot service releases.

Find the detailed changelogs for 1.2.6 here and the one for 1.3.1 here.

For all users building hypermedia based API, I’d like to announce that we shipped Spring HATEOAS 1.3 M2. We ship two major themes with the release:

• Revised support for HAL-FORMS and most of the additional property attributes derived from types or JSR-303 annotations. For details checkout the revamped section of the references docs or a more complete example.

• We significantly revamped the way we register the media type conversion within the WebMVC infrastructure. This is a response to challenges in selecting the best media type to render in certain Accept header edge conditions. This change should be a non-issue but it would be great if you could test the new setup for a spin and report any glitches you potentially encounter.

With Spring Data Lovelace just released in its generally available version last week, it is time to have a brief walk through the new features we have added. The release train is pretty packed with features. In this blog post, I cover the more general ones. Advanced, store-specific news is covered in the following blog posts:

• Jens Schauder introducing Spring Data JDBC

• Jens again on how to model aggregates with Spring Data JDBC

• Christoph Strobl on MongoDB

• Mark Paluch on Spring Data for Apache Cassandra & Redis

Read up on those? Alright, then let’s get started on the more general items…

On behalf of the Spring Data team, I'd like to announce the availability of the Lovelace RC2 release. This ships in preparation of Spring Boot 2.1 M2 and, of course, our own GA release mid-September. The release ships with 82 tickets fixed. You can find more details in the the updated and curated release wiki.

A pretty late but significant new feature has made it into the release: deferred repository initialization for Spring Data JPA. The feature allows your startup to use Spring Framework's JPA background initialization option more effectively and can significantly cut down startup time. See the previewing example…
