- commons-lang3 is no longer brought by Swagger Core (swagger-api#5323). - SwaggerAnnotationIntrospector methods take a MapperConfig<?> first parameter; overrides with the 2.x signature compile but are no longer called. - DETECT_PARAMETER_NAMES adds writeOnly properties to generated schemas for constructor parameters without a matching getter or field. - Mappers created outside ObjectMapperFactory silently drop $ref, $id, $schema... from Swagger models. See swagger-api#4991. Signed-off-by: Badr NASS LAHSEN <badr.nasslahsen@gmail.com>

MIGRATION.md. The change is documentation only, in one file.
until it declared the dependency itself.
SwaggerAnnotationIntrospectorsubclasses: its methods take aMapperConfig<?>first parameter. An overridewith the 2.x signature and no
@Overridestill compiles, and is silently never called.DETECT_PARAMETER_NAMES: constructor parameters without a matching getter or fieldbecome
writeOnlyschema properties. The example is verified against the 3.0.0 branch.ObjectMapperFactorysilently drop$ref,$id,$schema… from Swagger models, because ofJackson 3's accessor naming. springdoc-openapi lost the
$refs of a user-providedOpenAPIbean this way.Fixes:
