Maintainers

The Spring Framework does not use a CODEOWNERS file. Ownership is mapped here from git history (git shortlog, git log against main) over the last year. Names are git-author names.

Recent active contributors (last 12 months)

Name	Approximate commits (last 12 months)
Sam Brannen	585
Juergen Hoeller	380
Rossen Stoyanchev	261
Sébastien Deleuze	214
Brian Clozel	192
Stéphane Nicoll	26
Tran Ngoc Nhan	21
Yanming Zhou	14
Patrick Strawderman	10
Johnny Lim	10

These five (Brannen, Hoeller, Stoyanchev, Deleuze, Clozel) account for >88% of the last year's commits and are the de-facto core team.
