Exception When Using Entrust Middleware In Laravel 5.1

I have installed the Entrust package in my Laravel 5.1 application by adding it to my composer.json file and running composer update and followed all of the instructions to the letter. I am trying to use their middleware to protect some routes but I get the following exception:

ReflectionException in Container.php line 741:
Class App\Http\Zizaco\Entrust\Middleware\EntrustPermission does not exist

Here is the contents of my composer.json file:

Here is the content of my App\Http\Kernel.php file:

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
    /**
     * The application's global HTTP middleware stack.
     *
     * @var array
     */
    protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
    ];

    /**
     * The application's route middleware.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'clientIpCheck' => 'App\Http\Middleware\ClientIpCheck',
        'role' => Zizaco\Entrust\Middleware\EntrustRole::class,
        'permission' => Zizaco\Entrust\Middleware\EntrustPermission::class,
        'ability' => Zizaco\Entrust\Middleware\EntrustAbility::class,
    ];
}

And here is how I am trying to use the middleware in my routes.php file:

// secure admin routes
Route::group(['middleware' => 'permission:access_admin_area'], function()
{
    Route::get('admin', ['as' => 'dashboard', 'uses' => 'Admin\[email protected]']);
});

I'm pretty sure I've followed their instructions to the letter, it was all working until I tried to use their route middleware. Anyone know where I've gone wrong?

Answer

Turns out the code in the installation instructions is wrong. The route middleware definitions need a backslash on the front.

Broken example:

/**
 * The application's route middleware.
 *
 * @var array
 */
protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'clientIpCheck' => 'App\Http\Middleware\ClientIpCheck',
    'role' => Zizaco\Entrust\Middleware\EntrustRole::class,
    'permission' => Zizaco\Entrust\Middleware\EntrustPermission::class,
    'ability' => Zizaco\Entrust\Middleware\EntrustAbility::class,
];

Fixed example:

/**
 * The application's route middleware.
 *
 * @var array
 */
protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'clientIpCheck' => 'App\Http\Middleware\ClientIpCheck',
    'role' => \Zizaco\Entrust\Middleware\EntrustRole::class,
    'permission' => \Zizaco\Entrust\Middleware\EntrustPermission::class,
    'ability' => \Zizaco\Entrust\Middleware\EntrustAbility::class,
];

Thanks to xaoc for the heads up!
