DTO가 늘어나거나 삭제될때마다 이 코드도 수정해야 할것같아요.
1:1로 메소드로 맵핑하면 어떨까요?

안녕하세요 원우님 과제하느냐 고생많으셨습니다.
관점의 차이인데 개인적으로는 둘이 일치해서 같은 걸 사용하면 단점이 생길 수 있다고 생각해요. |

추후엔 이렇게 .class를 호출해서 Class 타입을 처리하는 리플렉션을 이용한 방법보단 쉬운 방법을 택해보시죠.

스프링이 알아서 붙여주긴할텐데. 어딘 붙고 어딘 안붙으면 안돼요.

✅ PR 포인트 & 궁금한 점
분할하니 의미 없는 convert만 처리하여 넘겨준다고 느껴졌습니다.
2 계층을 1개의 계층이라 보고 묶어도 괜찮을까요?
Reader가 뱉는 DTO가 일치하고, Store가 뱉는 DTO가 일치한다는 것을 알 수 있었습니다.
이 경우도 Reader와 Store를 나누는 것 중 이점이라고 볼 수 있을까요? 아니면 프로젝트가 작아서 생기는 우연인지 궁금합니다.
