Do mesmo modo que você pode declarar mais validações e metadados para parâmetros de consulta com `Query`, você pode declarar os mesmos tipos de validações e metadados para parâmetros de rota com `Path`.

## Importe `Path`

Primeiro, importe `Path` de `fastapi`:

//// tab | Python 3.10+

```Python hl_lines="1"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+

## Importer Path

Tout d'abord, importez `Path` de `fastapi`, et importez `Annotated` :

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

# path operationデコレータの依存関係

場合によっては*path operation関数*の中で依存関係の戻り値を本当に必要としないこともあります。

もしくは、依存関係が値を返さない場合もあります。

しかし、それでも実行・解決する必要があります。

このような場合、*path operation関数*のパラメータを`Depends`で宣言する代わりに、*path operation decorator*に`dependencies`の`list`を追加することができます。

##  *path operationデコレータ*への`dependencies`の追加

*path operationデコレータ*はオプショナルの引数`dependencies`を受け取ります。

それは`Depends()`の`list`であるべきです:

```Python hl_lines="17"

:skipRc

@setlocal

set ERROR_CODE=0

@REM ==== START VALIDATION ====
if not "%JAVA_HOME%"=="" goto javaHomeSet
for %%i in (java.exe) do set "JAVACMD=%%~$PATH:i"
goto checkJavaCmd

:javaHomeSet
set "JAVACMD=%JAVA_HOME%\bin\java.exe"

if not exist "%JAVACMD%" (
  echo The JAVA_HOME environment variable is not defined correctly, so Apache Maven cannot be started. >&2

# Dependencies in path operation decorators

In some cases you don't really need the return value of a dependency inside your *path operation function*.

Or the dependency doesn't return a value.

But you still need it to be executed/solved.

For those cases, instead of declaring a *path operation function* parameter with `Depends`, you can add a `list` of `dependencies` to the *path operation decorator*.
