Description

Spring defaults to naming many beans by either class or method names. When using multiple openapi.yaml files (e.g. for a versioning strategy), these names can collide and fail start up.
In my case the occurrence of multiple EnumConverterConfiguration's produces the issue.

Suggest a fix

Change @configuration Annotation in converter.mustache fixes the issue:

@Configuration(value = "{{configPackage}}.enumConverterConfiguration")

Fix is implemented in PR: #17738
