DateTimeFormat.ISO.DATE_TIME 의 스펙
코드 설명 및 문제 해결
중간에 T를 넣는 이유는 띄어쓰기로 인해서 값이 잘못 넘어올 수 있기 때문
사용한 date format은 iso 8601 표준을 따름
스프링 부트 서버에서 String을 LocalDateFormat으로 변환하기 보단 어노테이션을 이용해서 컨트롤러 단에 들어오기 전에 변환이 가능함.
주의할 점은 Format 중간에 ‘T’라고 되어 있더라도 따옴표를 추가해선 안됨.
추가하면 역직렬화가 실패함. (위의 오류가 발생한 원인)
또한 Jackson 라이브러리는 Spring Boot Starter web 2.x.x 부터는 기본으로 포함되어 있다.
결론 (이동욱 CTO님의 블로그에서 발췌한 것)
- Get요청시에는 @DateTimeFormat
- Post 요청, ResponseBody에서는 @JsonFormat
- Post 요청시에도 @DateTimeFormat이 적용될 수 있으나, @JsonFormat이 지정되어 있지 않을때만 가능하다.
