Spring Cloud Openfeign FeignClientFactoryBean#getObjectType() return null lead to "is not eligible..."

Describe the bug

Bean 'com.example.demo.DemoApplication$NameService' of type [org.springframework.cloud.openfeign.FeignClientFactoryBean] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

it‘s because FeignClientFactoryBean#getObjectType() return null, so spring will early init and i think it is a little worried.

even if this is not a bug actually, but it bothers me and i hope this info log will disappear :)

// AbstractAutowireCapableBeanFactory#getTypeForFactoryBean(String beanName, RootBeanDefinition mbd, boolean allowInit) 

// If we're allowed, we can create the factory bean and call getObjectType() early
if (allowInit) {
    FactoryBean<?> factoryBean = (mbd.isSingleton() ?
        getSingletonFactoryBeanForTypeCheck(beanName, mbd) :
    getNonSingletonFactoryBeanForTypeCheck(beanName, mbd));
    if (factoryBean != null) {
        // Try to obtain the FactoryBean's object type from this early stage of the instance.
        Class<?> type = getTypeForFactoryBean(factoryBean);
        if (type != null) {
            return ResolvableType.forClass(type);
        }
        // No type found for shortcut FactoryBean instance:
        // fall back to full creation of the FactoryBean instance.
        return super.getTypeForFactoryBean(beanName, mbd, true);
    }
}

Sample

@SpringBootApplication @EnableFeignClients public class DemoApplication {

public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);
}

@FeignClient("name")
static interface NameService {
    @RequestMapping("/")
    public String getName();
}

}
