|
|
whose ids are their fully-qualified class name.
|
|
|
|
Before:
|
|
|
|
```php
|
|
namespace App\Controller;
|
|
|
|
use App\Mailer;
|
|
|
|
class DefaultController
|
|
{
|
|
public function __construct(Mailer $mailer) {
|
|
// ...
|
|
}
|
|
|
|
// ...
|
|
}
|
|
```
|
|
```yml
|
|
services:
|
|
App\Controller\DefaultController:
|
|
autowire: true
|
|
```
|
|
|
|
After:
|
|
|
|
```php
|
|
// same PHP code
|
|
```
|
|
```yml
|
|
services:
|
|
App\Controller\DefaultController:
|
|
autowire: true
|
|
|
|
# or
|
|
# App\Controller\DefaultController:
|
|
# arguments: { $mailer: "@App\Mailer" }
|
|
|
|
App\Mailer:
|
|
