Motivation
The existing MVC implementation did not handle
CallNotPermittedExceptionand lacked a way to "resume without error," which is frequently needed in real-world production systems where graceful degradation is desired.Summary
This PR enhances the MVC
CircuitBreakerFilterFunctionsby adding missing error-handling cases and introducing a new configuration option (resumeWithoutError).The goal is to align the MVC implementation more closely with the WebFlux CircuitBreaker behavior and improve overall resilience and configurability.
Key Changes
CallNotPermittedExceptionCallNotPermittedException), the filter now returns:503 Service Unavailable
