FeignClient specified configuration class does not take effect - spring-boot

Question

I'm a novice at Stack Overflow. I really don't know why 'Ask Question' doesn't indicate the location to be formatted. I can only use Blackquote to wrap most non code segments. Maybe Stack Overflow can make questions friendly?
I use Nacos service registration, use Spring LoadBalancer
to initiate remote calls with openfeign, I specify a configuration
class to specify log output level and load balancing strategy for
FeignClient.
I extracted FeignClient and Configuration into separate module commons
// FeignClient Configuration
#Data
#Configuration
#ConfigurationProperties("at999.cloud.commons.feign")
public class FeignConfig{
private String logging;
private String rule;
#Bean
public Logger.Level level(){
System.out.println(">> " + logging + " >>");
switch(String.valueOf(logging)){
case "FULL":
return Logger.Level.FULL;
case "HEADERS":
return Logger.Level.HEADERS;
case "BASIC":
return Logger.Level.BASIC;
case "NONE":
case "null":
default:
return Logger.Level.NONE;
}
}
#Bean
public ReactorServiceInstanceLoadBalancer rule(Environment evnt,
LoadBalancerClientFactory lbcf, NacosDiscoveryProperties ndps)
throws ClassNotFoundException, InstantiationException, IllegalAccessException,
NoSuchMethodException, InvocationTargetException{
System.out.println(">>> " + rule + " >>>");
if(rule != null){
Class.forName(rule).asSubclass(ReactorServiceInstanceLoadBalancer.class);
String pn = LoadBalancerClientFactory.getName(evnt);
System.out.println("*** " + pn + " ***");
ObjectProvider<ServiceInstanceListSupplier> op = lbcf.getLazyProvider(pn, ServiceInstanceListSupplier.class);
if(rule.endsWith(".NacosLoadBalancer"))
return new NacosLoadBalancer(op, pn, ndps);
else{
Object or = Class.forName(rule).getDeclaredConstructor().newInstance(op, pn);
if(or instanceof ReactorServiceInstanceLoadBalancer){
return ReactorServiceInstanceLoadBalancer.class.cast(or);
}
}
}
return null;
}
}

#FeignClient(value="user-client", configuration=FeignConfig.class)

This is the service provider

This is the consumer of the service

I searched for a day and couldn't find a solution, GitHub traced some
source code, but without IDEA debugging, the laptop (a dozen years
ago) can only run light linux
I have tried removing FeignConfig's annotation #Configuration
The access interface will only appear 404
FeignClient does not resolve to an accessible ip:port after pulling
the service for the first time
