Support Composed Constraints

[michael-arndt-gcx]

Jakarta Bean Validation allows to compose constraints as described in 3.3. Constraint composition.

I'd like to implement basic support for this. My idea would be to add a preprocessing step to

swagger-core/modules/swagger-core/src/main/java/io/swagger/v3/core/jackson/ModelResolver.java

Line 1560 in df88c8a

protected void applyBeanValidatorAnnotations(BeanPropertyDefinition propDef, Schema property, Annotation[] annotations, Schema parent, boolean applyNotNullAnnotations) {

which flattens all Annotations. That means: when an annotation is annotated with javax.validation.Constraint, all its annotations are treated as if all annotations are on the annotated element.

This has been requested as feature e.g. in springdoc/springdoc-openapi#1486
