symfony - 在 symfony2 中加载应用程序的自定义配置文件

Question

我正在开发一个 symfony2 应用程序，我正在尝试包含位于 /src/AppBundle/Resources/Config/general.yml 中的自定义 yaml 配置

我遵循此处提供的示例 http://symfony.com/doc/current/cookbook/bundles/extension.html并在 src/AppBundle/DependencyInjection/AppExtension.php 文件中创建，内容如下:

<?php
namespace AppBundle\DependencyInjection;

use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Translation\Loader\YamlFileLoader;

class AppExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new YamlFileLoader(
        $container,
        new FileLocator("@AppBundle/Resources/config')
        );
        $loader->load('general.yml');
    }
}

然而，我卡在了这一点上，不知道如何让 symfony 执行这个文件并加载配置。

由于我没有看到您的 general.yml 文件的内容，我建议您使用类似下面的内容(我没有测试过，但应该没问题)。

假设这是你的 general.yml

doctrine:
    orm:
        entity_managers:
            encrypt:
                mappings:
                    MyEncryptBundle:
                        dir: Entity
                        type: annotations
                        prefix: My\EncryptBundle\Entity

无需创建此 yml 文件并导入它，您可以直接在 DependencyInjection 中设置所有内容，因此它会像下面这样。

namespace Application\FrontendBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
use Symfony\Component\Validator\Tests\Fixtures\Entity;

/**
 * This is the class that loads and manages your bundle configuration
 *
 * To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html}
 */
class ApplicationFrontendExtension extends Extension implements PrependExtensionInterface
{
    /**
     * {@inheritdoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.yml'); # another file of yours
        $loader->load('controllers.yml'); # another file of yours
        $loader->load('repositories.yml'); # another file of yours
    }

    public function prepend(ContainerBuilder $container)
    {
        $container->prependExtensionConfig(
            'doctrine',
            [
                'orm' => [
                    'entity_managers' => [
                        'encrypt' => [
                            'mappings' => [
                                'MyEncryptBundle' => [
                                    'dir'       => 'Entity',
                                    'type'      => 'annotation',
                                    'prefix'    => 'My\EncryptBundle\Entity'
                                ]
                            ]
                        ]
                    ]
                ]
            ]
        );
    }
}

或者你可以做点什么like this相反。
