Symfony - ClassNotFoundException in app_dev.php - php

Question

In my local version works normally, but when I put on the server, has this problem! Please help.
ERROR
ClassNotFoundException in app_dev.php line 27:
Attempted to load class "AppKernel" from the global namespace.
Did you forget a "use" statement for e.g. "Symfony\Bundle\FrameworkBundle\Tests\Functional\app\AppKernel" or "Symfony\Bundle\SecurityBundle\Tests\Functional\app\AppKernel"?
My app_dev.php :
<?php
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Debug\Debug;
// If you don't want to setup permissions the proper way, just uncomment the following PHP line
// read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
//umask(0000);
// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.

It looks like you're using your app/boostrap.php.cache file as the autoload, please change the following line
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
to
$loader = require __DIR__.'/../app/autoload.php';
Please also make sure that the following code exists in your composer.json file
"autoload": {
"classmap": [
"app/AppKernel.php",
"app/AppCache.php"
]
},
