`APIRouter`에 `dependencies`를 두는 것은 예를 들어 전체 *path operations* 그룹에 인증을 요구할 때 사용할 수 있습니다. 각 경로 처리에 개별적으로 dependencies를 추가하지 않아도 됩니다.

`prefix`, `tags`, `responses`, `dependencies` 파라미터는 (다른 많은 경우와 마찬가지로) 코드 중복을 피하도록 도와주는 **FastAPI**의 기능입니다.

### dependencies import하기 { #import-the-dependencies }

이 코드는 모듈 `app.routers.items`, 파일 `app/routers/items.py`에 있습니다.

To add a dependency on Guava testlib using Maven, use the following:

```xml
<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava-testlib</artifactId>
  <version>33.5.0-jre</version>
  <scope>test</scope>
</dependency>
```

To add a dependency using Gradle:

```gradle
dependencies {
  test 'com.google.guava:guava-testlib:33.5.0-jre'
}
```

        }
    }

    dependencies {
        dependency(AbsoluteId("Gradle_${vcsBranch.branchName.toCapitalized()}_$FINAL_RELEASE_BUILD_CONFIGURATION_ID")) {
            artifacts {
                buildRule = lastSuccessful()
                artifactRules = "version-info.properties => ./version-info-final-release"
            }
        }

    /**
     * Gets the scope of (transitive) dependencies that should be collected. Dependency collection refers to the process
     * of calculating the complete dependency tree in terms of artifact coordinates. In contrast to dependency
     * resolution, this does not include the download of the files for the dependency artifacts. It is meant for mojos
     * that only want to analyze the set of transitive dependencies, in particular during early lifecycle phases where

        return this;
    }

    /**

     *
     * @return The filter used to determine which of the artifacts in the dependency graph should be traversed or

    public ArtifactFilter getCollectionFilter() {
        return collectionFilter;
    }

    }

### Dependency Injection { #dependency-injection }

FastAPI includes an extremely easy to use, but extremely powerful <dfn title='also known as "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></dfn> system.

* Even dependencies can have dependencies, creating a hierarchy or **"graph" of dependencies**.
* All **automatically handled** by the framework.
