How to load openapi local files into swagger on localhost? (Files generated by restdocs)

I have my api documentation generated by restdocs through unit tests. Although it works fine for most of my needs, I'm still lacking a bit of the nice swagger features, so I was trying to have the best of both words by converting the restdocs into swagger. After trying for a long time, I finally managed to get it done with the help of some third part libraries (https://github.com/ePages-de/restdocs-api-spec https://github.com/BerkleyTechnologyServices/restdocs-spec). This generates the open api files under the static docs folder. However, when I try to access the swagger url http://localhost:8081/swagger-ui/index.html, It wouldn't show it there, which would have worked by default if adding swagger directly with the swagger annotation on the controller. I can manually import the openapi yml file and see it through the https://editor.swagger.io/ but there may be a better way to map swagger to automatically find the openapi files directly from my code so I can keep using the default swagger url for this?

Thank you.

UPDATE

Trying with the docs under the resources folder, but still getting the same error. I've opened a new question with details here Failed to load api definition when loading files from application properties

You have need to put the openapi specification yml in the resource folder and set springdoc.swagger-ui.url=/openapi-3.yaml in the application.properties file of spring boot app.

Checkout springdoc api documentation

In application properties need to make sure

spring.web.resources.add-mappings=false

shouldn't be added its preventing to serve static content.

Also openapi-3.0.yml should be placed inside of resources/static folder.
