스프링 데이터 JPA를 대비해서 메소드 이름을 그에 맞게 정해두셨다고 하셨는데요. 실무에서 스프링 데이터 JPA 말고 다른 기술을 결정했을 때도 메소드 이름을 그렇게 설계하는지 궁금합니다.예를 들어서 mybatis를 사용해서 프로젝트를 진행한다고 결정했을 때 먼저 Repository 인터페이스를 설계 할텐데 인터페이스 메소드 이름을 스프링 데이터 JPA 형식에 맞지 않게 정했다면 나중에 스프링 데이터 JPA로 변경하기 곤란할 것 같습니다.실무에서 스프링 데이터 JPA 말고 다른 기술을 사용하기로 결정했을 때도 이후에 스프링 데이터 JPA로 변경될 가능성을 고려해서 스프링 데이터 JPA의 Repository 메소드 이름 형식을 사용하나요?만약 스프링 데이터 JPA 메소드 이름 형식을 사용하지 않는다면 어떻게 해결하는지도 궁금합니다.

제목 그대로 MemberRepository 랑 Member가 어떻게 연결이 되는건가요?

이렇게 되어있는데 지금은 어떤 스프링부트를 선택해야하며 패키징하고 자바는 어떤걸 선택해야 하나요???

전체적인 흐름에 있어서 생각하는 부분들이 맞는지에 대한 궁금증이 생겨 질문드립니다다른 글들을 참고하였을 때Item은 현재, 별도의 DB가 없기 때문에 DB 역할을 하는 ItemRepository에 저장하기 위해 UploadFile(사용자가 업로드한 파일)를 사용하는 것이 맞나요?ItemForm은 form에서 넘어오는 file 타입을 저장하기 위해서는 MultipartFile 인터페이스를 사용해야 하기 때문에 MultipartFile 참조형을 가져오는 것이 맞나요?FileStore의 경우 실제 파일들이 저장되는 곳이며, 실제 파일들을 저장하고, Repository(실제 파일이 아닌 경로)에 저장하기 위해 형변환을 하는 역할을 하는 것이 맞나요?김영한 강사님에 말씀에 따르면 Repository는 실제 파일들을 저장하는 곳이 아닌 경로를 저장하는 곳이라고 말씀하셨는데 이 말은 즉 Repository에는 경로를 저장하고 해당 실제 파일은 FileStore에 저장되어 있다가 Repository를 통해 호출되면 해당 파일이 호출되는 것이 맞는지 궁금합니다.김영한 강사님께서 쉽고 자세하게 설명해주셨음에도 불구하고 이해가 많이 부족하여 여러가지 질문을 남깁니다...

선생님 안녕하세요 질문을 드리기 전에 스프링과 POJO에 대해 많이 찾아보고 고민했는데, 제가 제대로 이해한 게 맞는지 질문드리고 싶습니다.저는 스프링이 POJO를 지향하는 프레임워크인 이유를 이렇게 이해했습니다.엄밀히 말하면 DTO, VO처럼 인터페이스를 구현하지 않고 상위 클래스를 상속받지 않는 클래스들이 POJO라고 할 수 있습니다.그러나 컨트롤러 클래스는 @Controller라는 어노테이션이 필요하기에, 스프링이라는 프레임워크에 종속된 기술이며, 서비스 클래스도 인터페이스(PSA)를 구현하기에 엄밀히는 POJO가 아닙니다.그렇지만 POJO를 지향하는 이유가 결합도를 낮추고, 응집도를 높여 환경변화를 적게 받고 특정 기술에 종속되지 않기 위한 목적이 있습니다.비록 컨트롤러 클래스와 서비스 클래스는 POJO라고 할 수는 없지만, 최대한 POJO에 가깝게 결합도를 낮추고 응집도를 높여서 재사용성을 높이기 위해 DI, AOP, PSA 를 사용했습니다.즉, 완전한 POJO를 구현한 프레임워크는 아니지만, POJO를 지향하여 최대한 모듈 간 결합도를 낮추고 응집도를 높이고 재사용성을 높인 프레임워크라고 이해했습니다.혹시 제가 제대로 이해했는지 봐주시면 감사하겠습니다.
