안녕하세요.
Response에 내려오는 에러코드를 Enum으로 관리하는 방법을 공부해보고 정리한 글입니다.
Enum
-
Enum은 Eumeration로 열거형입니다.
열거형은 서로 연관된 상수들의 집합을 의미합니다. -
기존에 상수를 정의하는 방법이였던 final static string 과 같이 문자열이나 숫자들을 나타내는 기본자료형의 값을 enum을 이용해서 같은 효과를 낼 수 있습니다.
| 메소드 | 설명 |
|---|---|
| static E values() | 해당 열거체의 모든 상수를 저장한 배열을 생성하여 반환함. |
| static E valueOf(String name) | 전달된 문자열과 일치하는 해당 열거체의 상수를 반환함. |
| protected void finalize() | 해당 Enum 클래스가 final 메소드를 가질 수 없게 됨. |
| String name() | 해당 열거체 상수의 이름을 반환함. |
| int ordinal() | 해당 열거체 상수가 열거체 정의에서 정의된 순서(0부터 시작)를 반환함. |
Response
- 에러코드는 Response의 message 필드 값에 내려온다.
- Enum의 필드 값을 순회하면서 일치하는 에러코드를 가져온다.
- 에러코드를 통해 사전에 정의한 에러메세지를 출력한다.
ErrorCode
@Getter
public enum ErrorCode {
INVALID_PARAMS(400, "InvalidParams", "필수데이터 누락, 또는 형식과 다른 데이터를 요청하셨습니다.")
, UNAUTORIZED(401, "Unauthorized", "토큰 정보가 유효하지 않습니다.")
, UNAVAILABLE(401, "Unavailable", "회원가입이 완료되지 않은 사용자입니다.")
, NOT_FOUND(404, "NotFound", "존재하지 않는 데이터입니다.")
, CONFLICT(409, "Conflict", "데이터가 충돌되었습니다.")
;
ErrorCode (int status, , String code, String message) {
this.status = status;
this.code = code;
this.message = message;
}
private int status;
private String code;
private String message;
public static ErrorCode valueOfCode(String errorCode) {
return Arrays.stream(values())
.filter(value -> value.code.equals(errorCode))
.findAny()
.orElse(null);
}
}
Test
| 코드 | 상태 코드 | 에러 메세지 |
|---|---|---|
| InvalidParams | 400 | 필수데이터 누락, 또는 형식과 다른 데이터를 요청하셨습니다. |
| Unauthorized | 401 | 토큰 정보가 유효하지 않습니다. |
| Unavailable | 401 | 회원가입이 완료되지 않은 사용자입니다. |
| NotFound | 404 | 존재하지 않는 데이터입니다. |
| Conflict | 409 | 데이터가 충돌되었습니다. |
- 에러코드 "InvalidParams"
- 에러메세지 "필수데이터 누락, 또는 형식과 다른 데이터를 요청하셨습니다."가 출력되는지 확인한다.
