Symfony2 - bundle中的doctrine连接配置

我有一个使用我的附加包的项目。此捆绑包连接到其他数据库,我需要配置另一个数据库。

我希望在2个配置文件中建立此连接。

主配置:

# ROOT/app/config/config.yml:
doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   "%database_driver%"
                host:     "%database_host%"
                port:     "%database_port%"
                dbname:   "%database_name%"
                user:     "%database_user%"
                password: "%database_password%"
                charset:  UTF8

捆绑配置:

# src/SecondBundle/Resources/config/config.yml
doctrine:
    dbal:
        connections:
            secondBundle:
                driver:   "%secondBundle.database_driver%"
                host:     "%secondBundle.database_host%"
                port:     "%secondBundle.database_port%"
                dbname:   "%secondBundle.database_name%"
                user:     "%secondBundle.database_user%"
                password: "%secondBundle.database_password%"
                charset:  UTF8

捆绑扩展文件:

class SecondBundleExtension extends Extension
{
    /**
     * {@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('config.yml');
    }
}

在我看来,一切看起来都不错,但是当我试图运行时,我已经沟通了:

  

没有可以加载“doctrine”

的配置的扩展程序

您可以使用SecondBundle声明特定于您的捆绑包的第二个驱动程序(在您的示例中名为PrependExtensionInterface

首先将config.yml中的SecondBundle文件重命名为doctrine.yml(或任何其他非config.yml的名称。

立即更改您的SecondBundleExtension课程:

use Symfony\Component\DependencyInjection\Exception\InvalidArgumentException;
use Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface;
use Symfony\Component\Yaml\Exception\ParseException;
use Symfony\Component\Yaml\Parser as YamlParser;
// ...

class SecondBundleExtension extends Extension implements PrependExtensionInterface
{
    public function load(array $configs, ContainerBuilder $container)
    {
        // ...
    }

    public function prepend(ContainerBuilder $container)
    {    
        $yamlParser = new YamlParser();

        try {
            $doctrineConfig = $yamlParser->parse(
                file_get_contents(__DIR__.'/../Resources/config/doctrine.yml')
            );
        } catch (ParseException $e) {
            throw new InvalidArgumentException(sprintf('The file "%s" does not contain valid YAML.', $file), 0, $e);
        }

        $container->prependExtensionConfig('doctrine', $doctrineConfig['doctrine']);
    }
}

现在,您启用捆绑包时会自动注册secondBundle连接。

您可以将额外的配置添加到app/config/config.yml中的导入中,以便将其合并为完整的config

应用程序/配置/ config.yml

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: '@SecondBundle/Resources/config/config.yml' }

由于版本3.0以来a non-quoted string cannot start with @ or ` (reserved) nor with a scalar indicator (| or >)这一事实而更新了引号。
