display constraints from x-field-extra-annotation parameter of Swagger/OpenAPI definition

Content & configuration

Swagger/OpenAPI definition:

components:
 schemas:
   SomeDto:
     required:
       - someProperty
     type: object
     properties:
       someProperty:
         type: string
         x-field-extra-annotation:
               - "@jakarta.validation.constraints.NotEmpty"
              - "@org.hibernate.validator.constraints.UUID(allowNil = false)"

Swagger-UI configuration options:

SwaggerUI({
  // your config options here
})

?yourQueryStringConfig

Is your feature request related to a problem?

I use openapi-generator-maven-plugin to build DTO and Controller classes. I have to put some constraint annotations into x-field-extra-annotation of a parameter. But When I run the application I do not see these constraint annotations in swagger-ui.

Describe the solution you'd like

I want that swagger-ui displays values of x-field-extra-annotation for assosiated parameters of dto.

Describe alternatives you've considered

I tried to "override" indeh.html, and write there custom js plug whicj could display at least names on annotations from x-field-extra-annotation. But I figured out that swagger-ui does not receive any information from Swagger/OpenAPI definition .yaml file which is not shown in swagger-ui. I mean the dto's property does not contain x-field-extra-annotation parateters at all.

Additional context

Start with the Swagger/OpenAPI schema in the issue and the SwaggerUI configuration path, then trace how vendor extensions are retained and rendered for DTO properties and parameters. Done means values from x-field-extra-annotation are visible for the associated parameters in Swagger UI.
