SymfonyDependencyInjection:匯入多個資源(yaml)

我正在嘗試在非 Symfony 專案中實作 Symfony 依賴注入組件 ( https://symfony.com/doc/current/components/dependency_injection.html ) 。

如果我將所有服務和引數放入一個“services.yaml”檔案中，它會很好地作業。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%"

    # ...    

由于檔案變得非常大，我想將其拆分為不同的檔案，如下所述：https : //symfony.com/doc/current/service_container/import.html#importing-configuration-with-imports

所以我試過：

# 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%"

    # ...  

但在此配置中，我收到以下錯誤：

Fatal error: Uncaught Symfony\Component\DependencyInjection\Exception\RuntimeException: Cannot autowire service "OtherNamespace\Database\Drivers\MySqlDriver": argument "$host" of method "__construct()" is type-hinted "string", you should configure its value explicitly.

If I switch the import order, then it is the CookieSession that has a problem. It is like the import is overriding the parameters and services to only use the last one ? How can I split my services and their parameters in multiple files ?

Thank you !

uj5u.com熱心網友回復：

問題是我的服務從我databases.yaml和其他 yaml正確匯入到我的services.yaml檔案中，但在這個檔案中，我也有自動類轉換為服務。

所以我定義的服務被重新加載/轉換，但沒有引數和所有。我添加了排除項，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'
        ]

感謝@NicoHaase、@Cerad 和@WillB。為了他們的幫助！
