Symfony4使用外部类库作为服务 [英] Symfony4 use external class library as a service
问题描述
我有一个小的外部库,可以公开许多类。
I have a little external library that expose many classes.
进入我的symfony4项目中,我想从供应商处声明我的类,作为具有autowire和public的服务。
因此,我将我的库包含在composer中,并将这样的psr配置添加到composer.json中:
Into my symfony4 project I would like to declare my class from vendor, as a service with autowire and public. So I have include my library with composer and add psr configuration like this into composer.json:
"autoload": {
"psr-4": {
"App\\": "src/",
"ExternalLibrary\\": "vendor/external-library/api/src/"
}
}
之后,我尝试更改我的services.yaml像这样进入symfony:
After that I have tried to change my services.yaml into symfony like this:
ExternalLibrary\:
resource: '../vendor/external-library/api/src/*'
public: true
autowire: true
如果我启动测试或运行应用程序,则返回此错误:
If I launch tests or run the application returns me this error:
Cannot autowire service "App\Domain\Service\MyService": argument "$repository" of method "__construct()" references interface "ExternalLibrary\Domain\Model\Repository" but no such service exists. You should maybe alias this interface to the existing "App\Infrastructure\Domain\Model\MysqlRepository" service.
如果我在services.yaml中声明接口,则可以正常工作:
If I declare into services.yaml the interface this works fine:
ExternalLibrary\Domain\Model\Lotto\Repository:
class: '../vendor/external-library/api/src/Domain/Model/Repository.php'
public: true
autowire: true
但是我有很多类,我不想声明每个类,如何在不声明每个服务的情况下修复services.yaml?
But I have many classes and I don't want to declare each class, how can I fix services.yaml without declare every single service?
谢谢
推荐答案
您需要手工创建服务:
我没有对其进行测试,但是应该看起来像这样
You need to create services by hand: I did not test it but it should look like this
services.yaml
Some\Vendor\:
resource: '../vendor/external-library/api/src/*'
public: true # should be false
Some\Vendor\FooInterface:
alias: Some\Vendor\Foo # Interface implementation
Some\Vendor\Bar:
class: Some\Vendor\Bar
autowire: true
php
<?php
namespace Some\Vendor;
class Foo implements FooInterface
{
}
class Bar
{
public function __construct(FooInterface $foo)
{
}
}
更准确地说,您应该有以下类似内容
To be more precise you should have something like
ExternalLibrary\Domain\Model\Repository:
alias: App\Infrastructure\Domain\Model\MysqlRepository
