是否可以将接口注入Laravels Kernel.php?
我目前正在重构我的Laravel5项目,以便利用 我创建了一个存储库接口和一个存储库类:是否可以将接口注入Laravels Kernel.php?,php,laravel,dependency-injection,laravel-5,repository-pattern,Php,Laravel,Dependency Injection,Laravel 5,Repository Pattern,我目前正在重构我的Laravel5项目,以便利用 我创建了一个存储库接口和一个存储库类: interface UserRepositoryInterface { [...] } class UserRepository implements UserRepositoryInterface { [...] } 然后在服务提供者类中添加了必要的绑定: App::bind('App\Repositories\UserRepositoryInterface','App\Reposito
interface UserRepositoryInterface {
[...]
}
class UserRepository implements UserRepositoryInterface
{
[...]
}
然后在服务提供者类中添加了必要的绑定:
App::bind('App\Repositories\UserRepositoryInterface','App\Repositories\UserRepository');
并将接口注入控制器构造函数:
class UserController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct(UserRepositoryInterface $userRepository)
{
$this->userRepository = $userRepository;
}
}
这部分很好用。问题是我需要使用app\Console\Kernel.php类中的一些存储库方法,在那里我实现了一些预定任务。我尝试以类似的方式注入内核构造函数:
/**
* Create a new console kernel instance.
*/
public function __construct(Application $app, Dispatcher $events, UserRepositoryInterface $userRepository)
{
parent::__construct($app, $events);
$this->userRepository = $userRepository;
}
但是,这种方法不起作用(例如,在终端中运行“php artisan tinker”失败)。我得到以下错误:

我想知道是否可以将存储库接口注入内核,如果可以,我做错了什么?您做错了。我想您是直接在内核中的闭包中编写计划任务的。相反,将您的命令封装在逻辑中
然后,您可以在命令构造函数中分别定义每个命令依赖项,清理内核并编写一些可测试且漂亮的代码:)我不知道这是否可行,但是
$userRepository=\App::make('App\Repositories\UserRepositoryInterface')
应该可以正常工作,并且基本上具有相同的结果(虽然DI可能更干净、更容易测试,但到底是谁在测试内核?)虽然这个答案与原来的问题不同,但这里您没有使用依赖项注入。您直接引用了存储库。我遇到了同样的问题,我想做的是在命令文件中使用UserRepositoryInterface,并将其自动绑定到存储库,就像我在con中所做的一样特罗勒,这可能吗?
