Symfony 4-来自自定义捆绑包的服务不起作用

Question

我将symfony 3迁移到symfony 4.3，并且我的自定义包移动到：src/Bundles/FooBundle。

structure FooBundle:-依赖注入-配置。php-FooExtension。php-Event-Model-Resources-config-services。yml-Service-Twig-Exception-FooBundle。php

和文件bundle/FooBundle/Resources/config/services。亚马尔

services:
  foo:
    class: App\Bundles\FooBundle\Service\Foo
    arguments:
      - '%foo.argument1%'
      - '%foo.argument2%'
      - '%foo.argument3%'
  foo.listener.example:
    class: App\Bundles\FooBundle\Event\Listener\ExampleListener
    arguments: ['@annotations.reader']
    tags:
      - { name: kernel.event_listener, event: kernel.controller, method: onKernelController }
  foo.filter:
    class: App\Bundles\FooBundle\Filter\FilterConverter
    tags:
      - { name: request.param_converter }

捆绑/脚束/依赖注射/Configuration.php

<?php

namespace App\Bundles\FooBundle\DependencyInjection;

use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;

class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritdoc}
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder('foo');
        $treeBuilder->getRootNode()
            ->children()
            ->scalarNode('argument1')->isRequired()->end()
            ->scalarNode('argument2')->isRequired()->end()
            ->scalarNode('argument3')->isRequired()->end()
            ->end();

        return $treeBuilder;
    }
}

Bundles/FooBundle/DependencyInjection/footextension。php

<?php

namespace App\Bundles\FooBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;

/**
 * This is the class that loads and manages your bundle configuration.
 *
 * @link http://symfony.com/doc/current/cookbook/bundles/extension.html
 */
class FooExtension extends Extension
{
    /**
     * {@inheritdoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $container->setParameter('foo.argument1', $config['page_field_name']);
        $container->setParameter('foo.argument2', $config['per_page_field_name']);
        $container->setParameter('foo.argument3', $config['sort_field_name']);

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

和bundle注册：config/bundles。php

App\Bundles\FooBundle\FooBundle::class => ['all' => true],

配置包：

config/packages/foo。山药

foo:
  argument1: test1
  argument2: test2
  argument3: test3

完成了...运行应用程序和错误：无法自动连接服务"App\Bundles\FaBundle\Service\Foo"：方法"__construct（）"的参数"$agument1"没有类型提示，您应该显式配置其值。

但是，当我在config/services中添加conf时。亚马尔：

App\Bundles\FooBundle\Service\Foo:
  arguments:
    - '%foo.argument1%'
    - '%foo.argument2%'
    - '%foo.argument3%'

那工作。。。

问：为什么捆绑服务不起作用？

Answer 1

我想问题在于symfony中的默认配置将自动连线添加到应用程序名称空间下的所有类。

检查config/services下的配置。yml：

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App\:
        resource: '../src/*'
        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

您可以删除以下行：

    App\:
        resource: '../src/*'
        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

问题应该会消失。
