Symfony没有正确加载控制器:致命错误:调用成员函数addResource()

我在Symfony2中玩DDD，我添加了以下控制器:'src'Coredomain'Companies'RestBundle'Controller'CompanyController.php

namespace Coredomain'Companies'RestBundle'Controller;
use [...] ;
class CompanyController
{
    public function indexAction()
    {
        return $this->render('default/index.html.twig');
    }
}

至于路由，我有在我的主routing.yml:

coredomain_companies_rest:
    resource: "@CoredomainCompaniesRestBundle/Resources/config/routing.yml"

在'src'Coredomain'Companies'RestBundle'Resources'config'routing.yml中:

coredomain_companies_rest_company:
    resource: "@CoredomainCompaniesRestBundle/Controller/CompanyController.php"

现在当我浏览到任何页面或运行php app/console debug:router时，我得到:

PHP Fatal error:  Call to a member function addResource() on a non-object in /vagrant/coredomain/vendor/symfony/symfony/src/Symfony/Component/Routing/Loader/PhpFileLoader.php on line 45
[2015-06-09 12:03:32] php.CRITICAL: Fatal Error: Call to a member function addResource() on a non-object {"type":1,"file":"/vagrant/coredomain/vendor/symfony/symfony/src/Symfony/Component/Routing/Loader/PhpFileLoader.php","line":45,"level":-1,"stack":[]} 

当我检查PhpFileLoader.php:45时，我看到:

44| $collection = self::includeFile($path, $this);
45| $collection->addResource(new FileResource($path));

我检查了$path变量，它包含:

'vagrant'coredomain'src'Coredomain'Companies'RestBundle'Controller'CompanyController.php

然后我检查了$collection，它包含int(1)。所以self::includeFile($path, $this)返回1而不是一个对象。方法如下所示:

private static function includeFile($file, PhpFileLoader $loader)
{
    return include $file;
}

基本上include $path;返回1或true。这给我提出了两个问题。因为当我在那里放置一个断点时，当我删除路由并使用Symfony2附带的示例控制器时，似乎这是而不是运行。但是，当我为自己的控制器添加路由时，它确实运行。

那么我做错了什么，它为我的路由运行这部分代码?为什么这个返回1?这个PhpFileLoader不是用于类而是用于平面PHP文件吗?

谢谢。
