Spring Cloud Openfeign MicrometerCapability bean not being created

Describe the bug Feign metrics do not appear:

"feign.Client",
"feign.Client.http_response_code",
"feign.Feign",
"feign.codec.Decoder",
"feign.codec.Decoder.response_size",

Reason: org.springframework.cloud.openfeign.FeignClientsConfiguration.MicrometerConfiguration#micrometerCapability is not being created because it can't find a MeterRegistry. Report shows

   FeignClientsConfiguration.MicrometerConfiguration#micrometerCapability:
      Did not match:
         - @ConditionalOnBean (types: io.micrometer.core.instrument.MeterRegistry; SearchStrategy: all) did not find any beans of type io.micrometer.core.instrument.MeterRegistry (OnBeanCondition)

The weird is, I have everything on classpath spring-boot-starter-actuator, feign-micrometer and spring-cloud-starter-openfeign, and in fact a SimpleMeterRegistry is being created through org.springframework.boot.actuate.autoconfigure.metrics.export.simple.SimpleMetricsExportAutoConfiguration#simpleMeterRegistry.

To solve the issue I needed to add a bean myself:

    @Bean
    public SimpleMeterRegistry simpleMeterRegistry(Clock clock) {
        return new SimpleMeterRegistry(SimpleConfig.DEFAULT, clock);
    }

With that everything works fine.

Sample Simple app, a feign client, a config for importing @Import(FeignClientsConfiguration.class) (btw is that necessary?) :

@FeignClient(value = "numbersapi.com", url = "numbersapi.com")
public interface NumberFeignClient {
    @GetMapping("/{number}")
    String test(@PathVariable("number") int number);
}

@Configuration
@Import(FeignClientsConfiguration.class)
public class RegistryConfig2 {}


@Configuration
public class RegistryConfig {
// removing this bean makes it not work anymore    
@Bean
    public SimpleMeterRegistry simpleMeterRegistry(Clock clock) {
        return new SimpleMeterRegistry(SimpleConfig.DEFAULT, clock);
    }
}

@RestController
public class WebController {
    private final NumberFeignClient numberFeignClient;
    public WebController(NumberFeignClient numberFeignClient) {
        this.numberFeignClient = numberFeignClient;
    }
    @GetMapping("/hello")
    public String hello() {
        return numberFeignClient.test(new Random().nextInt(100));
    }
}

I have the same issue, the proposed workaround solved it for me as well.

Hello @johnnywiller, do you have a micrometer-registry-{system} dependency in your build setup (for example, micrometer-registry-prometheus)?

Sorry for the delay, so I tested with both including micrometer-registry-prometheus and without. Both yielded same result of not having feign metrics ootb.

Ok, @johnnywiller @LeoKotschenreuther please provide a minimal, complete, verifiable example that reproduces the issue - we'll look further into it then.
