Spring Cloud Gateway now adds first-class support for API versioning to help teams evolve services safely and
predictably. The addition of API versioning support to Spring Cloud Gateway allows for enhanced version
negotiation, enhanced route matching, better backwards compatibility and improved deprecation workflows. By
generating, standards-compliant OpenAPI specifications from domain-centric models and action-oriented API
endpoint designs, we’ll discuss how shifting toward action-based definitions produces clearer intent, improves
cross-team API discoverability, and enables richer tooling support, including compatibility with Model Context
Protocol–based client tools. By aligning gateway-defined routes and versioning metadata with well-structured
OpenAPI documents, teams can automate client generation, enforce consistency, and improve their use with AI
enabled intelligent applications and tools. Thus providing a stable base that lets teams advance their applications
into new opportunities. In this session, we’ll walk through practical patterns for header-based, URI-based, and
media-type versioning, and show how these strategies integrate seamlessly with the new Spring Boot 4
application model. Attendees will leave with clear guidance on designing developer-friendly, scalable API
versioning strategies that align with modern microservice and edge-service architectures.
