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;
}
}

Specify configuration properties
// Feign Client
@FeignClient(value="user-client", configuration=FeignConfig.class)
public interface UserClientFeign{
@GetMapping("/user")
User getUser();
}
This is the service provider
@GetMapping("/user")
public User getUser(){
user.setName(user.getName() + "(c)");
return user;
}
This is the consumer of the service
@Resource
private UserClientFeign userClientFeign;
@GetMapping("/get/user")
public User getUserServiceUser(){
return userClientFeign.getUser();
}
Consumers import commons modules
commons module spring.factories

Scanning doesn't seem to work
@ConfigurationPropertiesScan("com.at999.springcloud.nacos.commons.feign.config")

This is the commons directory structure

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
