Laravel 8 bindings 和 singletons 的特性
2021-06-23 11:06 更新
如果你的服务提供器注册了许多简单的绑定，你可能想用 bindings 和 singletons 属性替代手动注册每个容器绑定。当服务提供器被框架加载时，将自动检查这些属性并注册相应的绑定：
<?php
namespace App\Providers;
use App\Contracts\DowntimeNotifier;
use App\Contracts\ServerProvider;
use App\Services\DigitalOceanServerProvider;
use App\Services\PingdomDowntimeNotifier;
use App\Services\ServerToolsProvider;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* All of the container bindings that should be registered.
*
* @var array
*/
public $bindings = [
ServerProvider::class => DigitalOceanServerProvider::class,
];
/**
* All of the container singletons that should be registered.
*
* @var array
*/
public $singletons = [
DowntimeNotifier::class => PingdomDowntimeNotifier::class,
ServerProvider::class => ServerToolsProvider::class,
];
