Bekas DI pada bahagian atas CakePHP

Motivasi

Saya mahu menyuntik Perkhidmatan kepada Perintah dan Pengawal oleh bekas DI.
Selain itu, Perkhidmatan menggunakan Repositori yang disuntik.
Dokumen itu tidak menyebut kes ini seperti suntikan bersarang.

Bagaimana untuk melaksanakan

Perkhidmatan dan Repositori

interface SomeRepository {
  public getAll(): array;
}

class SomeRepositoryImpl implements SomeRepository
{
    public function getAll(): array
    {
        print('getAll()');
        return [];
    }
}

class SomeService
{
    private $someRepository;

    public function __construct(SomeRepository $someRepository)
    {
        $this->someRepository = $someRepository;
    }

    public function doSomething(): void
    {
        $this->someRepository->getAll();
    }
}

Perintah

use Cake\Command\Command;
use Cake\Console\Arguments;
use Cake\Console\ConsoleIo;
use Cake\Console\ConsoleOptionParser;

class SomeCommand extends Command
{
    private SomeService $service;

    public function __construct(SomeService $service)
    {
        parent::__construct();
        $this->service = $service;
    }

    public static function getDescription(): string
    {
        return 'Inject service through provider';
    }

    public function buildOptionParser(ConsoleOptionParser $parser): ConsoleOptionParser
    {
        $parser = parent::buildOptionParser($parser);
        return $parser;
    }

    public function execute(Arguments $args, ConsoleIo $io)
    {
        $this->service->doSomething();
    }
}

use Cake\Core\ContainerInterface;
use Cake\Core\ServiceProvider;

class CommandServiceProvider extends ServiceProvider
{
    protected $provides = [
        SomeCommand::class,
    ];

    public function services(ContainerInterface $container): void
    {
        $container
            ->add(SomeCommand::class)
            ->addArgument(SomeService::class);
    }
}

Pengawal

use Cake\Controller\Controller;

class SomeController extends Controller
{
    public function index(SomeService $service)
    {
        $service->doSomething();
        print('index()');
    }
}

Daftar ke bekas DI

use Cake\Core\ContainerInterface;
use Cake\Core\ServiceProvider;

class SomeServiceProvider extends ServiceProvider
{
    protected $provides = [
        SomeService::class,
    ];

    public function services(ContainerInterface $container): void
    {
        $container
            ->add(SomeRepository::class, SomeRepositoryImpl::class);
        $container
            ->add(SomeService::class)
            ->addArgument(SomeRepository::class);
    }
}

// Application.php
class Application extends BaseApplication
{
    // ...
    public function services(ContainerInterface $container): void
    {
        $container->addServiceProvider(new SomeServiceProvider());
        $container->addServiceProvider(new ControllerServiceProvider());
    }
    // ...
