用途：在一般控制器中调用不需要实例化直接调用，如：
use App\Facades\Common;
Common::test();
echo \Test::test();
app('common')->test();
一、在Services目录下创建CommonService.php
<php
namespace App\Services;
class
CommonService{
//一些公共方法
public function test(){
echo __method__;
}
}
二、在Facades目录下创建Common.php
<php
namespace App\Facades;
user Illuminate\Support\Facades\Facade;
class
Common extends Facade{
protected static function getFacadeAccessor()
{
return 'common';
}
}
三、在Providers目录下创建CommonProvider
<php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Services\CommonService;
class CommonProvider extends ServiceProvider
{
public function boot()
{
}
public function register()
{
$this->app->singleton('common', function(){
return new
CommonService
();});
}
}
四、在config配置文件中打开app.php
'providers' => [
......
App\Providers\CommonProvider::class,
],
'aliases' => [
'Test' => App\Facades\Common::class,
],
