Php 带有自定义配置yaml文件的Symfony 2

我已经在我的项目中创建了一个新的bundle和，并按照上的说明进行了操作

这部分工作正常，但当我尝试添加一个以我的bundle命名的新yaml文件时，我可能会在其他bundle config文件夹中创建类似的命名文件，并使用相同的标记将它们合并到bundles config中，并将其添加到扩展类中以进行加载，我会遇到错误：

InvalidArgumentException: There is no extension able to load the configuration for "foo_bar_notify" (in /path/to/symfony/src/Foo/Bar/NotifyBundle/DependencyInjection/../Resources/config/notify.yml). Looked for namespace "foo_bar_notify", found none

请有人指出我错过了什么或做错了什么

代码片段； 配置类

public function getConfigTreeBuilder()
{
    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('foo_bar_notify');

    $rootNode
        ->children()
            ->arrayNode('roles')
                ->requiresAtLeastOneElement()
                ->prototype('array')
                    ->children()
                        ->scalarNode('name')
                            ->isRequired(true)
                        ->end()
                        ->scalarNode('description')
                        ->end()
                        ->arrayNode('placeholders')
                            ->prototype('scalar')->end()
                        ->end()
                        ->booleanNode('html')
                            ->isRequired()
                            ->defaultValue(true)
                        ->end()
                        ->scalarNode('template')
                            ->isRequired(true)
                        ->end()
                    ->end()
                ->end()
            ->end()
        ->end();

    return $treeBuilder;
}

扩展类

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

    $loader = new YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
    $loader->load('services.yml');
    $loader->load('foo_bar_notify.yml');

    $container->setParameter('notify', $config);
}

public function getAlias()
{
    return 'foo_bar_notify';
}

主配置文件

foo_bar_notify:
    roles:
        software_developer:
            name: Alice
            description: Foo
            placeholders:
                - $name
                - $email
            html: true
            template: 'some/path'
        super_developer:
            name: Malfoy
            description: bar
            html: false
            template: 'some/path/over/here'

自定义yaml notify.yml

foo_bar_notify:
    roles:
        core_developer:
            name: core
            html: true
            template: 'some/path'

我已经得到了一个解决方案使用的答案

我的扩展类现在看起来像这样

private $configFileName = 'notify.yml';

public function load(array $configs, ContainerBuilder $container)
{  
    // see if there are any other notify.yml files defined in other bundles
    $finder = new \Symfony\Component\Finder\Finder();
    $finder
        ->directories()
        ->in($container->getParameter('kernel.root_dir') . '/../src/Foo/Bar/*Bundle/Resources')
        ->path('config');

    foreach ($finder as $c_dir) {
        $absolute_path = $c_dir.'/'.$this->configFileName;
        if (file_exists($absolute_path)) {
            $to_add = array_values(Yaml::parse(file_get_contents($absolute_path)));
            $configs[0] = $this->merge($configs[0], $to_add[0]);
        }
    }

    $processor = new Processor();
    $configuration = new Configuration();
    $config = $processor->processConfiguration($configuration, $configs);

    $loader = new YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
    $loader->load('services.yml');

    // set the processed values as a parameter
    $container->setParameter('notify', $config);
}
