Laravel 5 Command and Handler issue

问题

I am working one of my project with laravel 5. During the implementation i got struct with one issue which is related to command and handler.

I used artisan command to generate command

php artisan make:command TestCommand --handler

I generated command at app/commands folder "TestCommand.php"

<?php

namespace App\Commands;

use App\Commands\Command;

class TestCommand extends Command
{
public $id;
public $name;

public function __construct($id, $name)
{
    $this->id = $id;
    $this->name = $name;
}
}

Also my TestCommandHandler.php looks like this

<?php

namespace App\Handlers\Commands;

use App\Commands\TestCommand;
use Illuminate\Queue\InteractsWithQueue;

class TestCommandHandler
{
/**
 * Create the command handler.
 *
 * @return void
 */
public function __construct()
{
    //
}

/**
 * Handle the command.
 *
 * @param  TestCommand  $command
 * @return void
 */
public function handle(TestCommand $command)
{
    dd($command);
}
}

Whenever dispatch this command from controller it shows following issue

InvalidArgumentException in Dispatcher.php line 335:
No handler registered for command [App\Commands\TestCommand]

Please, Anybody help me to solve this problem. Thank you

By default Laravel 5.1.x does not included BusServiceProvider. So we should create BusServiceProvider.php under provider folder and include that in to config/app.php.

BusServiceProvider.php

<?php namespace App\Providers;

use Illuminate\Bus\Dispatcher;
use Illuminate\Support\ServiceProvider;

class BusServiceProvider extends ServiceProvider {

/**
 * Bootstrap any application services.
 *
 * @param  \Illuminate\Bus\Dispatcher  $dispatcher
 * @return void
 */
public function boot(Dispatcher $dispatcher)
{
    $dispatcher->mapUsing(function($command)
    {
        return Dispatcher::simpleMapping(
            $command, 'App\Commands', 'App\Handlers\Commands'
        );
    });
}

/**
 * Register any application services.
 *
 * @return void
 */
public function register()
{
    //
}

}

config/app.php

'providers' => [
    App\Providers\BusServiceProvider::class
]

So it may help others. Thank you
