我正在尝试在非 Symfony 项目中实现 Symfony 依赖注入组件 ( https://symfony.com/doc/current/components/dependency_injection.html ) 。

如果我将所有服务和参数放入一个“services.yaml”文件中，效果会很好。前任：

# services.yaml

parameters:
    mysql.host: "127.0.0.1"
    mysql.database: "database"
    mysql.username: "root"
    mysql.password: ""

    oracle.database: ""
    oracle.username: ""
    oracle.password: ""

    cookie.domain: ".site.local"
    cookie.lifetime: 0
    cookie.useHttps: true

services:
    _defaults:
        autowire: true
        autoconfigure: true

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

    OtherNamespace\:
        resource: '../someHomemadeLibrary/src/*'
    
    OtherNamespace\Database\Drivers\MySqlDriver:
        class: OtherNamespace\Database\Drivers\MySqlDriver
        arguments:
            $host: "%mysql.host%"
            $database: "%mysql.database%"
            $username: "%mysql.username%"
            $password: "%mysql.password%"

    # ...

由于文件变得非常大，我想将其拆分为不同的文件，如下所述：https ://symfony.com/doc/current/service_container/import.html#importing-configuration-with-imports

所以我尝试了：

# index.php

$containerBuilder = new ContainerBuilder();
$loader = new YamlFileLoader($containerBuilder, new FileLocator('config/'));
$loader->load('services.yaml');

# services.yaml

imports:
    - { resource: "databases.yaml" }
    - { resource: "sessions.yaml" }

services:
    _defaults:
        autowire: true
        autoconfigure: true

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


    OtherNamespace\:
        resource: '../someHomemadeLibrary/src/*'


# databases.yaml

parameters:
    mysql.host: "127.0.0.1"
    mysql.database: "database"
    mysql.username: "root"
    mysql.password: ""

services:
    OtherNamespace\Database\Drivers\MySqlDriver:
        class: OtherNamespace\Database\Drivers\MySqlDriver
        arguments:
            $host: "%mysql.host%"
            $database: "%mysql.database%"
            $username: "%mysql.username%"
            $password: "%mysql.password%"

    # ...

但是在这种配置中，我收到以下错误：

致命错误：未捕获的 Symfony\Component\DependencyInjection\Exception\RuntimeException：无法自动装配服务“OtherNamespace\Database\Drivers\MySqlDriver”：方法“__construct()”的参数“$host”是类型提示的“字符串”，您应该配置它的价值明确。

如果我切换导入顺序，那么是CookieSession有问题。就像导入覆盖参数和服务只使用最后一个？如何将我的服务及其参数拆分到多个文件中？

谢谢 ！

问题是我的服务被正确地从我的databases.yaml和其他 yaml 导入到我的services.yaml文件中，但是在这个文件中，我还自动将类转换为服务。

所以我定义的服务被重新加载/转换，但没有参数和所有。我添加了排除项，它有效！

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


    OtherNamespace\:
        resource: '../someHomemadeLibrary/src/*'
        exclude: 
        [
            '.../theClassFileDeclaredInAnotherYaml.php',
            '../or/a/whole/folder/not/to/be/loaded/again/*.php'
        ]

感谢@NicoHaase、@Cerad 和@WillB。为他们的帮助！
