Question

我在没有symfony框架的情况下使用symfony的DI。

这是composer.json的一部分

"require" : {
    "doctrine/orm" : "*",
    "doctrine/migrations" : "^1.5",
    "gedmo/doctrine-extensions" : "*",
    "symfony/dependency-injection" : "3.4.17",
    "symfony/config" : "3.4.17",
    "symfony/yaml" : "3.4.17",
    "twig/twig" : "^2.0",
    "symfony/form": "^3.4",
    "symfony/validator": "^3.4",
    "symfony/doctrine-bridge": "^3.4",
    "symfony/serializer": "^3.4",
    "ramsey/uuid": "^3.8",
    "ramsey/uuid-doctrine": "^1.5",
    "monolog/monolog": "^1.24",
    "wazaari/monolog-mysql": "^1.0",
    "twilio/sdk": "^5.28",
    "mobiledetect/mobiledetectlib": "^2.8",
    "symfony/console": "~3.4.23",
    "guzzlehttp/guzzle": "^6.3",
    "lcobucci/jwt": "^3.2",
    "symfony/cache": "^3.4",
    "symfony/finder": "^3.4",
    "beberlei/DoctrineExtensions": "^1.1",
    "symfony/http-foundation": "^3.4",
    "sinergi/browser-detector": "^6.1",
    "mpdf/mpdf": "~8.0",
    "symfony/proxy-manager-bridge": "^3.4"
},

这就是DI容器的构建方式

    if (file_exists($containerFile)) {
        require_once($containerFile);
        $container = new \ProjectServiceContainer();
    } else {
        $container = new ContainerBuilder();
        $container->setProxyInstantiator(new RuntimeInstantiator());

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

        $container->compile();

        $dumper = new PhpDumper($container);
        $containerDir = dirname($containerFile);
        file_put_contents($containerFile, $dumper->dump());
    }

在config / services.yml中，我已将service标记为lazy

  App\Services\MyService:
    public: true
    lazy: true

当我第一次运行some command时，它成为MyService的代理对象，当我第二次运行some command时，它从{{1} }，而且它并不懒惰。

生成的MyService

的一部分

cache/container.php

实际的问题是此函数内部根本没有使用cache/container.php变量，因此调用了protected function getMyServiceService($lazyLoad = true)的构造函数，但应该延迟，因为$lazyLoad不使用此方法根本没有服务。

symfony DI容器中的懒惰服务将被忽略
