是否可以在Symfony2中动态注册包? [英] Is it possible to dynamically register bundles in Symfony2?

问题描述

我有一个加载程序捆绑软件(LoaderBundle)，应该在同一目录中注册其他捆绑软件.

I have a loader bundle (LoaderBundle) that should register other bundles in the same directory.

/Acme/LoaderBundle/...
/Acme/ToBeLoadedBundle1/...
/Acme/ToBeLoadedBundle2/...

我想避免在AppKernel::registerBundles()中手动注册每个新包(在Acme目录中).最好，我希望LoaderBundle中的某些内容可以在每个单个请求上运行，并动态注册ToBeLoadedBundle1和ToBeLoadedBundle2.有可能吗?

I'd like to avoid manually registering every new bundle (in Acme directory) in AppKernel::registerBundles(). Preferably I'd like something in LoaderBundle to run on every single request and dynamically register ToBeLoadedBundle1 and ToBeLoadedBundle2. Is it possible?

推荐答案

未经测试，但您可以尝试类似

Untested but you could try something like

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;
use Symfony\Component\Finder\Finder;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            //... default bundles
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            // ... debug and development bundles
        }

        $searchPath = __DIR__.'/../src';
        $finder     = new Finder();
        $finder->files()
               ->in($searchPath)
               ->name('*Bundle.php');

        foreach ($finder as $file) {
            $path       = substr($file->getRealpath(), strlen($searchPath) + 1, -4);
            $parts      = explode('/', $path);
            $class      = array_pop($parts);
            $namespace  = implode('\\', $parts);
            $class      = $namespace.'\\'.$class;
            $bundles[]  = new $class();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
    }
}
