objectmapper jsonString to 객체 변형에서 date 포맷을 안하는 방법이 있을까요?

Question

api를 호출해서 얻은 값이 json형태인데거기서 날짜가 yyyyMMddHHmmss형태나 yyyyMMdd형태로 오더라구요ex) {"regDate" : "20201010223344"} 근데 이걸 objectMapper를 이용하여 readValue를 통해 json문자열을 객체에 담아줄때 에러가 나더라구요 ㅠㅠ 이럴경우에는 readValue를 이용하지못하고 하나하나 setter로 초기화해주어야하나요?... 필드에 JsonFormat에 pattern을 yyyyMMddHHmmss로 바꾸어주면 잘 받아지긴하는데..추후에 이걸 front에 리턴해줄때 format을 yyyy-MM-dd HH:mm:ss로 전송하고 싶어서요..ㅠㅠ 방법이없다면 그냥 JsonFormat으로 같은 형태로 받고프론트단에서 format을 이용하여 바꾸는게 이상적일까요? 밑에 코드는 예시입니다!! ObjectMapper mapper = new ObjectMapper(); Map map = new HashMap<>(); map.put("regDate", "20201010223344"); String jsonStr = mapper.writeValueAsString(map); JSONParser parser = new JSONParser(); Object obj = null; obj = parser.parse(jsonStr); JSONObject jsonObj = (JSONObject) obj; mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false); mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS,false); UsersEntity usersEntity = mapper.readValue(jsonStr, UsersEntity.class);@Entity @ToString @Table(name = "users", schema = "youngseok")

만약 직렬화할 때 형식과 역직렬화 시 형식을 달리 하고 싶다면 StdSerializer, StdDeserializer 클래스를 확장하여 양방향 직렬화 전략을 구성한 다음, &#64;JsonFormat 지우고 &#64;JsonDeserialize(using &#61; YourDeserializer.class) 어노테이션과 &#64;JsonDeserialize(using &#61; YourSerializer.class) 어노테이션을 둘 다 넣은 다음 구현한 클래스를 주입해야 합니다. 위 클래스를 검색하면 사용법이 나옵니다.
