Endpoints with only 3xx responses are rejected as invalid (no generated method) #413
Description
Description
When using openapi-processor-spring, operations that only declare redirect
responses (e.g. HTTP 302) are considered invalid and are not generated in the
Spring interface.
The processor reports an error similar to
endpoint '/logout' has no success 2xx response.
As a result, no method is generated for the endpoint.
Example OpenAPI
### Example OpenAPI
```yaml
/authorize:
get:
summary: OAuth2 authorize endpoint
responses:
'302':
description: Redirect to authorization server
headers:
Location:
schema:
type: string
This OpenAPI definition is valid and accurately describes the runtime behavior:
the endpoint always responds with a redirect and never returns a 2xx response.
Actual behaviour:
- The processor reports a validation error: endpoint has no success
2xxresponse - No method is generated in the Spring interface
Expected behaviour:
The processor should generate the endpoint method even if the operation only
defines 3xx responses.
Redirect-based endpoints are a valid and common HTTP pattern, especially in
browser-based flows such as:
- OAuth2 /authorize
- login / logout endpoints
- SSO / identity provider redirects
Requiring an artificial 2xx response (e.g. a dummy 204) just to satisfy the
generator leads to OpenAPI specifications that do not accurately reflect
runtime behavior.
