Laravel 8 bindings 和 singletons 的特性

如果你的服务提供器注册了许多简单的绑定,你可能想用 bindingssingletons 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,
    ];
}
