1. @ExceptionHandler 적용 시 HttpMediaTypeNotAcceptableException 에러
- Request/Response <-> Json 을 해주는 Jackson 라이브러리는 내부적으로 ObjectMapping API를 사용한다.
- ObjectMapping은 default로 getter/setter로 변환작업을 한다
- 문제 원인 : RoomResponse Class에 Getter를 정의하지 않음
@ExceptionHandler 적용 시 HttpMediaTypeNotAcceptableException 에러 해결
2. 궁금한것 : Page 단위 검색시 entity 조회 오류
- 조회할 데이터가 DB에 없는 경우 EntityNotFoundException이 발생하는데,
pageable + 메소드 이름으로 쿼리를 생성하면 해당 메소드에서는 별다른 exception이 발생하지 않는 것 같다 - Page에 저장되는 것이 exception이 발생하지 않는 원인인지 궁금하다/ 아니면 내가 발견하지 못한 exception이 발견되는 것 일지도
3. Spring Boot Controller test시 Json Key-Value 검증
- MockMvc로 http 요청을 하고 response(Json)의 필드 검증시
- .andExpect(jsonPath("$.[Key이름]").value(매칭되는 값)
- value에 객체를 넣고 싶다면
- value(objectMapper.convertValue(객체, LinkedHashMap.class))
- value(객체) 로 실행하면 아래와 같은 에러가 발생한다
- Spring에서 Json은 LinkedHashMap으로 관리되어 객체와 직접 비교는 불가능한듯 하다(확실한것은 아님)
- objectMapping로 convert해줘야
java.lang.AssertionError: At JSON path "$.option", value <{bedNum=1, bedroomNum=1, bathroomNum=0.5}> of type <java.util.LinkedHashMap> cannot be converted to type <org.programmers.staybb.domain.room.Option>
