創建symfony的配置樹構建多維數組

Question

我想創建一個配置自己的套件是這樣的：

my_filters: 
    filter_type_a: 
     - \MyBundle\My\ClassA 
     - \MyBundle\My\ClassA2 
    filter_type_b: 
     - \MyBundle\My\ClassB 

的my_filters應該是可變長度的數組，而my_filters.filter_type_a應變量數組長了。

我試圖

$treeBuilder = new TreeBuilder(); 
$rootNode = $treeBuilder->root('my_bundle'); 
$rootNode 
    ->children() 
     ->arrayNode('my_filters') 
      ->prototype('array') 
       ->prototype('array') 
        ->children() 
         ->scalarNode('my_filters')->end() 
         ->end() 
       ->end() 
      ->end() 
     ->end() 
    ->end() 

，但我得到了以下錯誤：Invalid type for path "my_bundle.my_filters.filter_type_a.0". Expected array, but got string。

這裏，在這裏我設置配置：

class MyBundleExtension extends Extension 
{ 
    public function load(array $configs, ContainerBuilder $container) 
    { 
     $this->loadServices($container); 
     $this->loadConfig($configs, $container); 
    } 

    private function loadConfig(array $configs, ContainerBuilder $container) 
    {  
     $configuration = new Configuration(); 
     $config = $this->processConfiguration($configuration, $configs); 
     $container->setParameter('my_bundle.my_filters', $config['my_filters']); 
    } 

    private function loadServices(ContainerBuilder $container) 
    { 
     $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config')); 
     $loader->load('services.yml'); 
    } 
} 

我看不到我的錯，誰能告訴我？

要匹配的配置

my_bundle: 
    my_filters: 
     filter_type_a: 
      - \MyBundle\My\ClassA 
      - \MyBundle\My\ClassA2 
     filter_type_b: 
      - \MyBundle\My\ClassB 

您需要配置樹構建器下面的代碼：

$rootNode = $treeBuilder->root('my_bundle'); 
$rootNode 
    ->children() 
     ->arrayNode('my_filters') 
      ->prototype('array') 
       ->prototype('scalar')->end() 
      ->end() 
     ->end() 
    ->end()
