The circuit breaker name follows this pattern `<feignClientName>#<calledMethod>`. When calling a `@FeignClient` with name `foo` and the called interface method is `bar` then the circuit breaker name will be `foo_bar`.
The circuit breaker name follows this pattern `<feignClientClassName>#<calledMethod>(<parameterTypes>)`. When calling a `@FeignClient` with `FooClient` interface and the called interface method that has no parameters is `bar` then the circuit breaker name will be `FooClient#bar()`.
NOTE: As of 2020.0.2, the circuit breaker name pattern has changed from `<feignClientName>_<calledMethod>`.
Using `CircuitBreakerNameResolver` introduced in 2020.0.4, circuit breaker names can retain the old pattern.
Providing a bean of `CircuitBreakerNameResolver`, you can change the circuit breaker name pattern.
