如何正确设置Symfony2中的默认配置值?

我已经构建了一个我希望能够从配置文件配置的服务。我已经能够根据需要使其工作,但是当我查看其他捆绑包时,看不到我必须使用的相同配置设置。我觉得这是一个黑客。 我需要的是将配置值设置为可选,这意味着如果它不在config.yml文件中,则使用默认值。我已经通过在Configuration.php包文件中添加以下内容来完成此操作:

namespace ChrisJohnson00\ApiProfilerBundle\DependencyInjection;

...
class Configuration implements ConfigurationInterface
{
public function getConfigTreeBuilder()
{
    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('chris_johnson00_api_profiler');

    $rootNode
        ->children()
            ->scalarNode('warning_threshold')
                ->info('Changes the warning threshold time (ms).  This is used to change the toolbar to yellow when the total response time is > this value')
                ->example("5000")
                ->defaultValue("5000")
                ->end()
            ->scalarNode('error_threshold')
                ->info('Changes the error threshold time (ms).  This is used to change the toolbar to red when the total response time is > this value')
                ->example("10000")
                ->defaultValue("10000")
                ->end()
        ->end()
    ;

    return $treeBuilder;
    }
}

但这不能单独使用,我必须将以下内容添加到我的bundle扩展文件的加载函数

namespace ChrisJohnson00\ApiProfilerBundle\DependencyInjection;

...
class ChrisJohnson00ApiProfilerExtension extends Extension
{

    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config        = $this->processConfiguration($configuration, $configs);

        $container->setParameter('chris_johnson00_api_profiler.warning_threshold', $config['warning_threshold']);
        $container->setParameter('chris_johnson00_api_profiler.error_threshold', $config['error_threshold']);

        $loader = new Loader\XmlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
        $loader->load('services.xml');
    }
}

如何在我的扩展文件中不需要$container->setParameter(...)的情况下配置我的软件包的配置参数?
