[Spring] class 이름 중복으로 인한 오류

패캠의 spring 강의를 듣는 도중 오류발생

강의랑 코드를 비교해봐도 틀린게 없어 오류메세지를 상펴보니,,

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class....

Annotation-specified bean name 'apiController' for bean class [com.example.hello.reponse.controller.ApiController] conflicts with existing, non-compatible bean definition of same name and class [com.example.hello.getAPI.controller.ApiController]

 

클래스 내임이 중복되서 bean생성이 안됐던것

강의에서는 hello하위 패키지에 해당하는 것들을 모두 새로운 프로젝트를 생성해가며 설명했기때문에 

하나의 프로젝트에서 패키지를 나눠가면 공부한결과 나온 오류였다.

 

수정

class명 수정으로 간단하게 해결!!
