如何让自动连接在symfony/依赖注入中工作？

// src/Service/MyService.php
namespace App\Service;

class MyService
{
    private $dependency;

    public function __construct(MyDependency $dependency)
    {
        $this->dependency = $dependency;
    }

    public function doSomething()
    {
        // 使用依赖项执行操作
        $this->dependency->doSomethingElse();
    }
}

// src/Service/MyDependency.php
namespace App\Service;

class MyDependency
{
    public function doSomethingElse()
    {
        // 执行其他操作
    }
}

// src/Controller/MyController.php
namespace App\Controller;

use App\Service\MyService;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class MyController extends AbstractController
{
    /**
     * @Route("/example", name="example")
     */
    public function example(MyService $myService)
    {
        $myService->doSomething();
        // ...
    }
}
