## Dependências para um grupo de *operações de rota*

Mais a frente, quando você ler sobre como estruturar aplicações maiores ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md){.internal-link target=_blank}), possivelmente com múltiplos arquivos, você aprenderá a declarar um único parâmetro `dependencies` para um grupo de *operações de rota*.

## Dependências globais

    @Override
    @J2ktIncompatible // serialization
    @GwtIncompatible // serialization
    Object writeReplace() {
      return super.writeReplace();
    }

    // No longer used for new writes, but kept so that old data can still be read.
    @GwtIncompatible // serialization
    @J2ktIncompatible
    @SuppressWarnings("unused")

    prefix="/admin",
    tags=["admin"],
    dependencies=[Depends(get_token_header)],
    responses={418: {"description": "I'm a teapot"}},

## Exemplo

Para um exemplos simples, vamos considerar uma estrutura de arquivos semelhante ao descrito em [Bigger Applications](../tutorial/bigger-applications.md){.internal-link target=_blank} e [Testing](../tutorial/testing.md){.internal-link target=_blank}:

 *  New: Switch our Internationalized Domain Name (IDN) implementation to [UTS #46 Nontransitional
    Processing][uts46]. With this fix, the `ß` code point no longer maps to `ss`. OkHttp now embeds
    its own IDN mapping table in the library.
