Make it easier to map MessageSourceProperties onto a user-provided AbstractResourceBasedMessageSource by henriquejsza · Pull Request #51484 · spring-projects/spring-boot · GitHub
This adds a ResourceBasedMessageSourceConfigurer bean that applies MessageSourceProperties to any AbstractResourceBasedMessageSource. The auto-configured ResourceBundleMessageSource now uses the configurer, while the configurer remains available when no resource bundle is found or when an application defines its own message source.
The conditions continue to use current-context lookup so parent/child context behavior is preserved. Tests cover configurer availability, configuring a user-defined ReloadableResourceBundleMessageSource, and using a user-provided configurer.
