What is different between the InstanceIsolationRequestHandler and CircuitBreakerRequestHandler

[longweiwork]

What do you want to ask?

When I add some circuitbreaker config and trigger fuse, the InstanceIsolationRequestHandler will intercept request and return InstanceIsolationException, but I want to return CircuitBreakerException, so what should I do to meet my expectations. Looking forward to your answer, thanks~

The instance isolation priority is greater than the circuit breaker priority, so the InstanceIsolation RequestHandler intercepts the request and ultimately returns an InstanceIsolation Exception. Therefore, it is currently not supported to modify the returned exception to a Circuit BreakerException through configuration or other means.
