However, the Java code we have is not fully annotated, which causes several consequences:
* IDE warnings can be misleading
* Redundant null checks may increase binary size, hurt performance, and increase cognitive load for readers
* Missing null checks may cause NullPointerException
* Bridging with Kotlin code is polluted with platform types
* Some public APIs have incorrect nullability annotations (both overly restrictive and overly permissive)

이를 통해 **여러 위치**에서 **모델을 재사용** 할 수 있고 모든 매개변수에 대한 유효성 검사 및 메타데이터를 한 번에 선언할 수도 있습니다. 😍

/// note | 참고

이 기능은 FastAPI 버전 `0.115.0` 이후부터 지원됩니다. 🤓

///

/// tip | 팁

동일한 기술이 `Query`, `Cookie`, 그리고 `Header`에 적용됩니다. 😎

**Pydantic 모델**에 필요한 **쿠키** 매개변수를 선언한 다음, 해당 매개변수를 `Cookie`로 선언합니다:
