Laravel 5 routes are not working - php

Question

I'm migrating from Laravel 4 to Laravel 5.
Only following is working:
Route::get('/some-url', function(){
echo "Some text";
});
Following is not working:
Route::get('/get-customer-info', 'CustomerController#info');
I created the controller in: app\Http\Controllers\CustomerController.php
So, whenever I redirect to a controller, it always set object not found
Here is my controller:
<?php
namespace App\Http\Controllers;
class CustomerController extends Controller
{
function __construct()
{
View::share('root', URL::to('/'));
}
public function info()
{
echo "ok";
}
}
I moved index.php file to the root.
Here is the index.php file on the
<?php
/**
