This Week in Spring - November 24th, 2020

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’re healthy, happy and safe, as always. Now then, we’ve got a ton of things to get to this week so let’s get to it!

Spring Data 2020.0 - New and Noteworthy in Spring Data R2DBC 1.2

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
