/// info | 정보

이 예시에서 `X-Key`와 `X-Token`이라는 커스텀 헤더를 만들어 사용했습니다.

그러나 실제로 보안을 구현할 때는 통합된 [보안 유틸리티 (다음 챕터)](../security/index.md){.internal-link target=_blank}를 사용하는 것이 더 많은 이점을 얻을 수 있습니다.

## 의존성 오류와 값 반환하기

평소에 사용하던대로 같은 의존성 *함수*를 사용할 수 있습니다.

### 의존성 요구사항

(헤더같은) 요청 요구사항이나 하위-의존성을 선언할 수 있습니다:

    public void setSource(String source) {
        this.source = source;
    }

    @Override
    public void add(Problem.Severity severity, String message, int line, int column, Exception cause) {
        Problem problem = new DefaultProblem(message, severity, source, line, column, cause);

        problems.add(problem);
    }

 * with {@link #where} and types are resolved using {@link #resolveType}.
 *
 * <p>Note that usually type mappings are already implied by the static type hierarchy (for example,
 * the {@code E} type variable declared by class {@code List} naturally maps to {@code String} in
 * the context of {@code class MyStringList implements List<String>}). In such case, prefer to use

 * but reduces variability and avoids starvation.
 *
 * <p>This class and its iterator implement all of the optional methods of the {@link
 * Collection} and {@link Iterator} interfaces.
