Using Spring with OpenAPI
summary
Demonstrates turning Spring MVC code into reusable OpenAPI artifacts by generating a YAML with springdoc (build- or runtime), producing a Spring server and a Java client with the OpenAPI Generator Maven plugin, and implementing the generated API to return a test payload ("hello spring one"). Shows runtime Swagger UI and a generated client that compiles, then packages the service into a container and registers the spec into Tanzu Application Platform so the cluster UI discovers and exposes the API descriptor.
