yml 文件的 Treebuilder 验证

Question

我创建了一个配置类并构建了一个树来定义我在该类中的配置，但我想它很丑那么我的问题是找到一个解决方案来简化我的类？

<?php
  namespace Myapp\Mybundle\DependencyInjection;

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


class Configuration implements ConfigurationInterface
{
/**
 * {@inheritDoc}
 */

public function getConfigTreeBuilder()
{

    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('em_profession');

    $rootNode
        ->children()
                 ->arrayNode('region')
         ->isRequired()
                 ->requiresAtLeastOneElement()
                 ->useAttributeAsKey('id')
                            ->prototype('array')
                                       ->children()

                                                                                                                       ->end()
                                                                                                                ->end()

                                                                                                     ->end()

                                                                                                  ->end()

                                                                                       ->end()
                                                                                 ->end()
                                                                            ->end()

                                                                       ->end()

                                                                  ->end()
                                                         ->end()

                                                     ->end()

                                             ->end()
            
                                      ->end()
                             ->end()
         ->end()
        ->end()
    ;

    return $treeBuilder;
}

我的配置工作正常，但它非常大，所以我将其最小化以简化它并停止重复代码。

编辑

好的，我知道这个解决方案，但我想我不能在我的配置中应用它，例如在 Twig 配置文件中，他们在“->end()”之后的类末尾使用自定义函数，但在我的配置中我在“prototype()”中使用它，我也有很多重复的代码，但是 child inside child inside child...所以很难正确地最小化它...

点赞Twig configuration file：使用方法：

$rootNode = $treeBuilder->root('em_profession');
$this->addMyCustomSection($rootNode);

然后在addMyCustomSection方法中：

private function addMyCustomSection(ArrayNodeDefinition $rootNode)
{
    // Continue modifying $rootNode
}
