Php 处理多参数的依赖注入Symfony

我实际上正在尝试自动连接一个类，其目的是构建查询。 类构造函数如下所示：

#App\Services\RepositoryDirector
class RepositoryDirector
{

    public function __construct(BuilderQueryRepositoryInterface $builderQueryRepository, FilterInterface $filter)
    {
        $this->_builderQueryRepository = $builderQueryRepository;
        $this->_filter = $filter;
    }
}

    #
    # Director repository services
    #
    app.services.repository_director.product:
        public: true
        class: App\Services\RepositoryDirector
        arguments:
            $builderQueryRepository: '@App\Repository\ProductRepository'
            $filter: '@App\Services\Filters\ProductFilter'

    app.services.repository_director.cart:
        public: true
        class: App\Services\RepositoryDirector
        arguments:
            $builderQueryRepository: '@App\Repository\CartRepository'
            $filter: '@App\Services\Filters\CartFilter'

    #
    # Controller
    #
    App\Controller\ProductController:
        public: true
        arguments:
            $productRepositoryDirector: '@app.services.repository_director.product'

    App\Controller\CartController:
        public: true
        arguments:
            $cartRepositoryDirector: '@app.services.repository_director.cart'

请注意，这两个参数都是接口，因此它可能会根据我实现RepositoryDirector的位置而改变

我尝试在两个名为ProductController和CartController的控制器中实现此对象

# App\Controller\ProductController 
class ProductController extends AbstractController
{
    private RepositoryDirector $_cartRepositoryDirector;

    public function __construct(ProductRepository $productRepository, ProductFilter $productFilter)
    {
        $this->_productRepositoryDirector = new RepositoryDirector($productRepository, $productFilter);
    }

    // Controller logic

但问题是我这里不使用自动布线，这是强耦合的，因为我不使用DI

我想要的是这样的东西：

# App\Controller\ProductController 
class ProductController extends AbstractController
{
    private RepositoryDirector $_productRepositoryDirector;

    public function __construct(RepositoryDirector $productRepositoryDirector)
    {
        $this->_productRepositoryDirector = $productRepositoryDirector;
    }

    // Controller logic

App\Controller\ProductController:
    public: true
    arguments:
        $productRepositoryDirector: ['@App\Repository\ProductRepository', '@App\Services\ProductFilter']

因此，我必须配置

config/services.yaml

来告诉Symfony，当我使用

$productRepositoryDirector

作为参数时，我希望它使用两个参数创建一个新对象

RepositoryDirector

：

ProductRepository$ProductRepository

ProductFilter$ProductFilter

我在考虑这样做：

# App\Controller\ProductController 
class ProductController extends AbstractController
{
    private RepositoryDirector $_productRepositoryDirector;

    public function __construct(RepositoryDirector $productRepositoryDirector)
    {
        $this->_productRepositoryDirector = $productRepositoryDirector;
    }

    // Controller logic

App\Controller\ProductController:
    public: true
    arguments:
        $productRepositoryDirector: ['@App\Repository\ProductRepository', '@App\Services\ProductFilter']

但这不起作用，我得到以下错误：

无法自动连线服务“App\Services\RepositoryDirector”：参数 方法“\uu construct（）”引用的“$builderQueryRepository” 接口“App\Repository\BuilderQueryRepositoryInterface”，但没有这样的接口 服务存在。您可能应该将此接口别名为其中一个 现有服务：“App\Repository\AreaCodeRepository”， “App\Repository\CompanyRepository”、“App\Repository\DataRepository”， “App\Repository\GroupRepository”， “App\Repository\ParamStyleRepository”， “App\Repository\ParamTypeDatasetRepository”， “App\Repository\ParamTypeFormatRepository”， “App\Repository\ParamTypeRepository”， “App\Repository\ParameterGroupRepository”， “应用程序\存储库\参数存储库”， “应用程序\存储库\电话号码存储库”， “应用程序\存储库\产品存储库”， “App\Repository\UserTokenRepository”， “App\Repository\ValueRepository”

我一直在阅读，但它并没有为我的问题提供任何解决方案。

我终于找到了解决方案

您必须如下配置

config/services.yaml

：

#App\Services\RepositoryDirector
class RepositoryDirector
{

    public function __construct(BuilderQueryRepositoryInterface $builderQueryRepository, FilterInterface $filter)
    {
        $this->_builderQueryRepository = $builderQueryRepository;
        $this->_filter = $filter;
    }
}

    #
    # Director repository services
    #
    app.services.repository_director.product:
        public: true
        class: App\Services\RepositoryDirector
        arguments:
            $builderQueryRepository: '@App\Repository\ProductRepository'
            $filter: '@App\Services\Filters\ProductFilter'

    app.services.repository_director.cart:
        public: true
        class: App\Services\RepositoryDirector
        arguments:
            $builderQueryRepository: '@App\Repository\CartRepository'
            $filter: '@App\Services\Filters\CartFilter'

    #
    # Controller
    #
    App\Controller\ProductController:
        public: true
        arguments:
            $productRepositoryDirector: '@app.services.repository_director.product'

    App\Controller\CartController:
        public: true
        arguments:
            $cartRepositoryDirector: '@app.services.repository_director.cart'

我错过了

类

关键字，这是由于phpsform自动完成，我很幸运找到的

如果你仔细阅读，你会注意到这个关键字与别名的用法完全一样，正如我在上面的代码中所做的那样
