Hi, Spring fans! Welcome to another jam-packed installment of This Week in Spring! It's the week of Thanksgiving here in the United States and I feel like I've got a ton of things and a ton more people for which and for whom to be thankful, and a huge, constant part of that is you, dear community. I say this in this column all the time, but you - the community - are the main reason that Spring is worth doing. I know that I speak for the entire Spring team when I say: thank you! And, speaking for myself, I hope that, whether you're in the US celebrating Thanksgiving or anywhere else, that you…

Spring Data Elasticsearch is one of the community modules shipped with the 2020.0 release. On behalf of P.J. Meisch, who is doing most of the heavy lifting these days, we’re happy to share his insights on the current release.

On behalf of everyone that has contributed, I am pleased to announce that Spring Native for GraalVM 0.8.3 has been released and is available from Spring milestone repository, check the updated reference documentation for more details.

In practice, the target is to support your Spring application (typically a Spring Boot one), unmodified, on this new…

Spring Data Neo4j is a Spring Data community project that is maintained and developed by Neo4j, Inc. On behalf of the team working on the module at Neo4j, we are happy to share their insights about recent changes and new features shipped with the 2020.0.0 release.

Neo4j users who use Spring Boot 2.3 require special attention because the configuration infrastructure for Spring Data Neo4j 6.0 has changed in an incompatible way.

That said, not only has the configurational infrastructure changed, but the whole project changed.

The module has some history and went through several major changes. For…

Hi, Spring fans! In this episode Josh Long (@starbuxman) talks to Dan North (@tastapod), creator of BDD, optimizer of teams and all around legend.

This release is a major milestone in Spring's R2DBC support. Spring support for R2DBC started as an experimental project two years ago to evaluate how a reactive SQL integration might look. With this release, Spring Data R2DBC underwent a major refactoring by moving several components into a dedicated spring-r2dbc module and deprecating components that are provided by the Spring Framework. Besides that change, Spring Data R2DBC ships with the following most notable changes:

• Add lifecycle callbacks through the EntityCallback API
• Reactive auditing
• Pass-through of enum values and Postgres Geo types
