From 5f5430408319d3613535fb129fc6b8e0e5bfc9cb Mon Sep 17 00:00:00 2001 From: Soby Chacko Date: Wed, 16 Jul 2025 22:26:33 -0400 Subject: [PATCH] GH-3930: Add Jackson 3 support; deprecate Jackson 2 Fixes: https://github.com/spring-projects/spring-kafka/issues/3930 * Manage dependencies, similar way we do for Jackson 2 * Add Jackson 3 counterparts for existing Jackson 2 based classes (mostly copy/paste) * Deprectate Jackson 2 classes * Update tests * Initial round of updates in docs Signed-off-by: Soby Chacko --- build.gradle | 9 + samples/sample-01/README.adoc | 4 +-
