해결 과정

엔티티에 @JsonIgnore 붙이기

Account 엔티티의 응답값으로 Point를 직렬화 하지 못하도록 @JsonIgnore를 붙였다.

여전히 무한참조가 발생한다.
- 사실, 이것은 당연한 것이다. 해당 API로 응답받으려는 데이터는 Point인데, 여기에 Account 객체가 포함되어 있으며, 양방향 매핑 되어있기 때문에 무한 참조 오류가 발생한 것이다.
  
  PointDto.Response 와 같은 응답 Dto 타입이 아닌 Point 객체 그 자체가 응답 받도록 되어 있었다.
  해결 방법은 두 가지이다.

- 1. Point 엔티티의 Account 필드에 @JsonIgnore 붙이기

=> 정상적으로 Account가 응답되지 않음을 확인할 수 있다.

그러나 PointDto.Response를 만들어 매핑해주는 것이 아키텍처적으로 더 건강하고 올바르다고 볼 수 있다.

- 2. PointDto.Response 만들어 반환하기

엔티티를 그대로 클라이언트에게 전달하기 보다 필요한 정보만을 담아 반환하는 것이 좋다. Http 통신 비용을 절감하고, 아키텍쳐 설계와 보안상 이점을 가져다 줄 수 있기 때문이다.
마찬가지로 예외가 발생하지 않는다.
