Symfony2路由不受支持的密钥

I'm learning Symfony 2 but I have some problems. Using a tutorial, I created this route in the routing.yml inside bundle:

acme_demo_homepage:
path:     /hello/{name}
defaults: { _controller: AcmeDemoBundle:Default:index }

random:
path:     /random/{limit}
defaults: { _controller: AcmeDemoBundle:Random:index }

and Eclipse shows me an error at line where defaults is declared and tells me that : is unexpected.

I have created the controller:

<?php
namespace Acme\DemoBundle\Controller;
use Symfony\Component\HttpFoundation\Response;

class RandomController
{


public function indexAction($limit)
{
    return new Response('<html><body>Number: '.rand(1, $limit).'</body></html>');
}

}

but when I try to execute localhost/app_dev.php/random/10 this error appears:

The routing file "C:\xampp\htdocs\progetti\Symfony\src\Acme\DemoBundle/Resources/config/routing.yml" contains unsupported keys for "acme_demo_homepage": "random". Expected one of: "resource", "type", "prefix", "pattern", "path", "host", "schemes", "methods", "defaults", "requirements", "options", "condition".

    I think this an indentation issue. From YAML Spec:

    "In YAML block styles, structure is determined by indentation.

    In general, indentation is defined as a zero or more space characters at the start of a line.To maintain portability, tab characters must not be used in indentation, since different systems treat tabs differently. Note that most modern editors may be configured so that pressing the tab key results in the insertion of an appropriate number of spaces    . "

    So:

    acme_demo_homepage:
    path:     /hello/{name}
    defaults: { _controller: AcmeDemoBundle:Default:index }

random:
    path:     /random/{limit}
    defaults: { _controller: AcmeDemoBundle:Random:index }

    Alternatively you can set your routes in PHP (it's my preference). For instance:

    <?php
 //src/Acme/DemoBundle/Resources/config/routing.php

use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Route;

$collection = new RouteCollection();

# main route
$collection->add('_index', new Route('/dashboard/index/{page}/{year}/{month}', array(
    '_controller' => 'AcmeDashboardBundle:Default:index',
    'page'        => 1,
    'year'        => date('Y'),
    'month'       => date('n'),
)));

return $collection;
//end of file
