如何使用Symfony中的不同配置(ConfigurationInterface)加载同一文件中的不同配置

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class MyConfiguration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder('my_bundle');
        $rootNode = $treeBuilder->getRootNode();

        $rootNode
            ->children()
                ->scalarNode('option1')->defaultValue('default_value1')->end()
                ->scalarNode('option2')->defaultValue('default_value2')->end()
            ->end();

        return $treeBuilder;
    }
}

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;

class MyBundleExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new MyConfiguration();
        $config = $this->processConfiguration($configuration, $configs);

        // 使用$config中的配置进行相应的操作
        // ...

        // 可以使用$container来注册服务等
        // ...
    }
}
