Use when versioning Spring MVC or WebFlux APIs in Spring Boot 3 / Spring Framework 6. Covers explicit URL, header, and media-type strategies, compatibility rules, and deprecation handling.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API Versioning (Boot 3 / Framework 6)
Boot 3 does not provide Boot 4's built-in mapping `version` attribute. Choose one explicit
strategy and keep it consistent: URL segments, a request header, or media-type parameters.
## Prefer a visible, testable contract
For a public API, `/api/v1/orders` and `/api/v2/orders` are usually the clearest choice. If URLs
must remain stable, resolve a request header at the web boundary and route to versioned handlers.
Do not hide version selection in business services or duplicate it across filters and controllers.
```java
@RestController
@RequestMapping("/api/v1/orders")
class OrderV1Controller {
@GetMapping("/{id}")
OrderV1 get(@PathVariable UUID id) { ... }
}
```
Document supported versions in OpenAPI, define a removal policy, and return a consistent error for
unsupported versions. Add `Deprecation`, `Sunset`, and `Link` headers through a response advice or
filter when retiring a version.
## Migration boundary
Keep version-specific DTOs and controllers thin. Map both versions to the same application use
case, and do not copy domain logic into each version. Add contract tests for every supported

How to install
mdr add rrezartprebreza/spring-boot-skills/api-versioning@sha256:029ff8005a159823The line at the top of this page pins the label git:20260807.5f992d7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
