Welcome to another installment of You May Not Need Another Library For That (YMNNALFT)! I've spent a lot of time since 2016 illuminating (or trying to, anyway!) some of the more enormous opportunities in the Spring ecosystem in my Spring Tips videos. Today, however, I come to you in a different spirit, wanting to focus on the little, sometimes hidden, gems that do fantastic things and that might spare you an additional third-party dependency and its implied complexity.

Integrating two services separated by a common, potentially volatile, and overwhelmed network is one of the most challenging…

HTTP services are a common source of data…

Spring Data has migrated its entire history of issues from Jira to GitHub. The goal of this blog post is to give you context and details about this migration.

Migration Details

Spring Data issues have been managed for over ten years in Jira. Today, every issue and every comment has been imported into GitHub. There is a lot to consider in such a move, so let's take a tour and go over some details.

Spring Data consists of 19 individual projects, each one of which is associated with its own issue tracker namespace. Four projects (Spring Data Build, BOM, Envers, and R2DBC) have been using GitHub…
