+/**
+ * Feign is a declarative web service client. It makes writing web service clients easier.
+ * To use Feign create an interface and annotate it.
+ * It has pluggable annotation support including Feign annotations and JAX-RS annotations.
+ * Feign also supports pluggable encoders and decoders.
+ * Spring Cloud adds support for Spring MVC annotations and for using the same HttpMessageConverters used by default in Spring Web.
+ * Spring Cloud integrates Eureka, as well as Spring Cloud LoadBalancer to provide a load-balanced http client when using Feign.
+ *
+ * 쉽게 말하면 RestTemplate, RestClient 등의 `HTTP Client`를 어노테이션으로 선언하여 사용하는 것이라 생각하면 된다.
+ * 인터페이스를 만들고 @FeignClient 를 선언하기만 하면 구현체는 런타임에 알아서 만들어진다.
+ *
+ * @see org.springframework.cloud.openfeign.FeignClient
