### 도커파일

이제 같은 프로젝트 디렉터리에 다음과 같은 파일 `Dockerfile`을 생성합니다:

```{ .dockerfile .annotate }
# (1)
FROM python:3.9

# (2)
WORKDIR /code

# (3)
COPY ./requirements.txt /code/requirements.txt

# (4)
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (5)

import org.codelibs.fess.util.ComponentUtil;
import org.lastaflute.di.core.SingletonLaContainer;
import org.lastaflute.di.core.exception.ComponentNotFoundException;

import jakarta.annotation.PostConstruct;

public class DocumentHelper {
    private static final Logger logger = LogManager.getLogger(DocumentHelper.class);

    protected static final String SIMILAR_DOC_HASH_PREFIX = "$";

But adding the type annotations will allow your editor to give you better support and detect errors.

///

## Without Pydantic

Et seront aussi utilisés dans chaque *opération de chemin* de la documentation utilisant ces modèles :

## Support de l'éditeur

Dans votre éditeur, vous aurez des annotations de types et de l'auto-complétion partout dans votre fonction (ce qui n'aurait pas été le cas si vous aviez utilisé un classique `dict` plutôt qu'un modèle Pydantic) :
