Introduction: OpenAPI and RAML are two popular languages used in API documentation. 1) SHALL designate the OAS feature set. 0) to validate properties that are not known. It seems insane that given explicit instructions to use it, it cant seem to properly generate code to create, track, run etc You have to define and communicate the request and response interfaces to your RESTful API somehow so that callers know what you expect in the request and what they can expect in a response. Learn about JSON Schema, its use cases and benefits, and how it’s used in APIs. The springdoc-openapi-maven-plugin plugin works with the spring-boot-maven plugin. Maybe there's a later version. I would like to suggest that a compromise that would be functionally identical to nullable but compatible with JSON Schema:.
