Dynamic OpenAPIs with Spring Cloud Gateway
summary
Shows a working solution that generates a single aggregated OpenAPI from many service specs, exposes only endpoints marked with the extension x-bmw-public, rewrites public paths and tags, and prunes unused schemas. Uses Swagger/OpenAPI libraries to merge and transform YAML and the programmatic Spring Cloud Gateway API to create routes on the fly; the gateway polls services and refreshes routes every five minutes. Prototype completes in a one-week spike and runs in production over a year without issues.
