[Spring] HTTP 요청 - 기본, 헤더 정보 조회

HTTP 요청 - 기본, 헤더 정보 조회

애노테이션 기반의 스프링 컨트롤러는 다양한 파라미터를 지원한다.

HTTP 요청 헤더 정보를 조회하기 위한 코드를 작성한 후, @Slf4j 로깅 라이브러리를 이용해 각 요청에 대한 로그를 남겨 확인해보았다.

• HttpServletResponse: 서블릿 기반의 응답 객체
• HttpMethod: HTTP 메서드 정보 조회
• Locale: 언어 정보 조회(우선 순위가 높은 locale 출력)
• @RequestHeader MultiValueMap<String, String> headerMap
  • 모든 HTTP 헤더를 MutliValue 형식으로 조회
