How to generate OpenApi 3.0 spec from existing Spring Boot App? : <p>I have a project (Spring Boot App + Kotlin) that I would like to have an Open API 3.0 spec for (preferably in YAML). The Springfox libraries are nice but they generate Swagger 2.0 JSON. What is the best way to generate an Open Api 3.0 spec from the annotations in my controllers? Is writing it from scratch the only way?</p>
