我正在使用Symfony的依赖注入组件(独立,不在Symfony应用程序中),版本v3.3.13
尝试新的自动服务加载。
如果我手动定义服务,则正确加载该类:
# services.yml
myasset:
class: Mysite\Asset\Asset
# in a PHP file
$container->get('myasset'); # works
如果我设置了自动加载,则会失败并显示错误消息: ReflectionException:类在第1070行的/var/www/vendor/symfony/dependency-injection/ContainerBuilder.php中不存在
# services.yml
_defaults:
autowire: true
autoconfigure: true
public: false
Bloggi\:
resource: '../src/*'
public: true
# in a PHP file
$container->get(Mysite\Asset\Asset::class);
失败的原因是找到了类并创建了服务定义,但定义的class
属性为null
,用于自动加载的服务。

我的DIC配置如下:
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
$container = new ContainerBuilder();
$loader = new YamlFileLoader($container, new FileLocator(__DIR__));
$loader->load(__DIR__ . '/../config/services.yml');
缺失的行是$container->compile();
工作定义
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
$container = new ContainerBuilder();
$loader = new YamlFileLoader($container, new FileLocator(__DIR__));
$loader->load(__DIR__ . '/../config/services.yml');
$container->compile();
