我正在构建一个扩展来从所有已安装的bundle加载配置文件.

我的扩展看起来像这样:

namespace Acme\MenuBundle\DependencyInjection;
// use ...
use Acme\MenuBundle\DependencyInjection\Configuration;

class AcmeMenuExtension extends Extension {
    public function load(array $configs, ContainerBuilder $container) {

        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $finder = new \Symfony\Component\Finder\Finder();
        $finder
            ->directories()
            ->in($container->getParameter('kernel.root_dir') . '/../src/*/*Bundle/Resources')
            ->path('config');

        $possibleLocations = array();
        foreach ($finder as $c_dir) {
            $possibleLocations[] = $c_dir->getPathName();
        }

        $loader = new Loader\YamlFileLoader($container, new FileLocator($possibleLocations));
        $loader->load('menu.yml');
    }
}

然后是我的(非常简单的)Configuration类:我将来会添加一个更复杂的树,但是现在我希望它可以使用它:

namespace Acme\MenuBundle\DependencyInjection;
// use ...

class Configuration implements ConfigurationInterface {  
    public function getConfigTreeBuilder() {
        $treeBuilder = new TreeBuilder();
        $rootNode …
