通过PHP-DI（自动装配）工作变得苗条

Question

[我试图在PHP-DI和Autowiring工作时变得苗条，但没有成功。也许我对自动布线的理解有误。

我建立了一个新项目并创建了以下Index.php：

require __DIR__ . '/../vendor/autoload.php';

use userservice\core\services\UserServiceInterface;
use userservice\infrastructure\services\UserService;
use userservice\webservice\controller\UsersController;
use DI\Container;

$app = \DI\Bridge\Slim\Bridge::create();
$container = $app->getContainer();
$container->set(UserServiceInterface::class, UserService::class);
$container->set(UsersController::class, UsersController::class);


$app->get('/user', [UsersController::class, 'get']);

$app->run();

UsersController

namespace userservice\webservice\controller;

use userservice\core\services\UserServiceInterface;

class UsersController{

    /**
     *
     * @var UserServiceInterface
     */
    private $userService;

    public function __construct(UserServiceInterface $userService) {
        $this->userService = $userService;
    }

    public function get(\Psr\Http\Message\ResponseInterface $response, \Psr\Http\Message\RequestInterface $request){
        //$user = $this->userService->get();
        $response->getBody()->write("Test");
        return $response;
    }
}

在上面的示例中，我得到以下错误消息：

Non-static method userservice\webservice\controller\UsersController::get() should not be called statically in

我找到了一个可行的解决方案，如何在映射到接口时使用PHP-DI自动装配：

require __DIR__ . '/../vendor/autoload.php';

use userservice\core\services\UserServiceInterface;
use userservice\infrastructure\services\UserService;
use userservice\webservice\controller\UsersController;
use userservice\core\repositories\UserRepositoryInterface;
use userservice\infrastructure\repositories\UserRepository;

/**
 * Mapping of classes to interfaces
 */
$definitions = [
    //REPOSITORIES
    UserRepositoryInterface::class => DI\get(UserRepository::class),

    //SERVICES
    UserServiceInterface::class => DI\get(UserService::class),
];

$builder = new DI\ContainerBuilder();
$builder->addDefinitions($definitions);
$container = $builder->build();
$app = \DI\Bridge\Slim\Bridge::create($container);
$app->get('/user', [UsersController::class, 'get']);

$app->run();
