This seems to be a new warning with Spring Boot 3.2.0:

Cache miss for REQUEST dispatch to '/actuator/health/readiness' (previous null). Performing MatchableHandlerMapping lookup. This is logged once only at WARN level, and every time at TRACE.

Logger name: org.springframework.web.servlet.handler.HandlerMappingIntrospector

I'd expect actuator endpoints like readiness and liveness never to be cached, and to not cause any warnings.

This is due to https://github.com/spring-projects/spring-framework/issues/31588 This should go away once https://github.com/spring-projects/spring-security/issues/14128 is done.

This is not a bug and does not reflect the caching status of the actuator, but rather some internal routing state with the web framework.

There's nothing that can be done here. As Brian described above, this is due to https://github.com/spring-projects/spring-framework/issues/31588 and will be addressed by https://github.com/spring-projects/spring-security/issues/14128.

And the same response from Spring Boot's perspective. If you must comment, please do so on https://github.com/spring-projects/spring-security/issues/14128.

Alright I'm locking this conversation because we explained the situation several times already but we keep getting the same question. Please read comments above.
