I wanna change default load banlancer rule with below configuration

ribbon.NFLoadBalancerRuleClassName=charles.sc.consumer.WeightedMetadataRule

but it not work, I must assign serviceId like below

someService.ribbon.NFLoadBalancerRuleClassName=charles.sc.consumer.WeightedMetadataRule

I can register WeightedMetadataRule as a spring bean, but it will disable all client's customization config.

org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration code sniper below:

@Bean
@ConditionalOnMissingBean
public IRule ribbonRule(IClientConfig config) {
	if (this.propertiesFactory.isSet(IRule.class, name)) {
		return this.propertiesFactory.get(IRule.class, config, name);
	}
	ZoneAvoidanceRule rule = new ZoneAvoidanceRule();
	rule.initWithNiwsConfig(config);
	return rule;
}

for this purpose: config default setting, and clients can have it's own setting replace default.

I extends org.springframework.cloud.netflix.ribbon.PropertiesFactory, and change below method:

public String getClassName(Class clazz, String name) {
	if (this.classToProperty.containsKey(clazz)) {
		String classNameProperty = this.classToProperty.get(clazz);
		String className = environment.getProperty(name + "." + NAMESPACE + "." + classNameProperty);
		if(!StringUtil.hasText(className )){
			className = environment.getProperty(NAMESPACE + "." + classNameProperty);
		}
		return className;
	}
	return null;
}

It works fine for me. But PropertiesFactory fields are all private, it seems not want we extend this class, have there any other grace way?
