Overwrite server URLs for static/custom OpenAPI Specs

[coiouhkc]

Is your feature request related to a problem? Please describe.

When using static/custom OpenAPI Spec to be the source for the Swagger UI, one currently doesn't seem to have a possibility to overwrite the server URL (which is not known at the design/spec phase of writing the spec and is subject to change based on the deployment/ target env).

See e.g. https://quarkus.io/guides/openapi-swaggerui#quarkus-smallrye-openapi_quarkus-smallrye-openapi-servers

Describe the solution you'd like

I'd like to have an option to overwrite the server URL(s) in the custom statically served OpenAPI Spec.

One possible solution (which I implemented as a workaround in current project) would be to use an interceptor doing a preHandle on the springdoc.swagger-ui.url and given that it's set and called replaces the server(s) portion of the static/custom OpenAPI Spec with contents of the newly added property springdoc.swagger-ui.serverUrl(s).

Describe alternatives you've considered

• Solution based off Desired Server URLs #2750 doesn't work with statically served custom OpenAPI Specs

Additional context

• if this feature request gets accepted, happy to work on a PR.

@coiouhkc,

You can already Customize Servers via application.yml #2948
Or you have already ServerBaseUrlCustomizer.
