如何在Shopware 5中注册我的服务和组件？

Question

在services.xml中注册我的服务和组件有问题

当我试图注册组件时，这就是我收到的结果。

Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException：

致命错误:未命名的服务"task.task_subscriber“依赖于不存在的服务"task.service.random_product”。在/var/www/shopware/vendor/symfony/dependency-injection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php:31\nStack trace:\n#0 /var/www/shopware/vendor/symfony/dependency-injection/Compiler/AbstractRecursivePass.php(60)：Symfony\Component\DependencyInjection\Compiler\CheckExceptionOnInvalidReferenceBehaviorPass->processValue(Object(Symfony\Component\DependencyInjection\Reference)，false)\n#1 /var/www/shopware/vendor/symfony/dependency-injection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php(28)：Symfony\Component\DependencyInjection\Compiler\AbstractRecursivePass->processValue(Array，中/var/www/shopware/vendor/symfony/dependency-injection/Compiler/AbstractRecursivePass.php(67)：Symfony\Component\DependencyInjection\Compiler\CheckExceptionOnInvalidReferenceBehaviorPass->processValue(Array)\n#3 /var/www/shopware/vendor/symfony/dependency-injection/Compiler/CheckExceptionOnInvalidReferenceBehaviorPass.php中的\n#2 /var (第31行)

这是我的services.xml

​

<services>
    <service id="task.task_subscriber" class="Task\Subscriber\TaskSubscriber">
        <argument>%task.plugin_name%</argument>
        <argument>%task.plugin_dir%</argument>
        <argument type="service" id="task.components.random_product" />
        <argument type="service" id="shopware.plugin.cached_config_reader" />
        <tag name="shopware.event_subscriber" />
    </service>

    <service id="task.random_product" class="Task\Components\RandomProduct">
        <argument type="service" id="dbal_connection"/>
    </service>
</services>

谁能给我解释一下有什么问题吗？

Answer 1

向id="task.random_product"注册类RandomProduct

因此，您需要在其他服务中使用相同的id。

所以这应该是可行的

<services>
    <service id="task.task_subscriber" class="Task\Subscriber\TaskSubscriber">
        <argument>%task.plugin_name%</argument>
        <argument>%task.plugin_dir%</argument>
        <argument type="service" id="task.random_product" />
        <argument type="service" id="shopware.plugin.cached_config_reader" />
        <tag name="shopware.event_subscriber" />
    </service>

    <service id="task.random_product" class="Task\Components\RandomProduct">
        <argument type="service" id="dbal_connection"/>
    </service>
</services>

在类TaskSubscriber中，可以将RandomProduct传递给

代码中参数和我们依赖项注入的__construct按相同的顺序

所以看起来会是这样

<?php

namespace Task\Subscriber;

use Task\Components\RandomProduct;

class TaskSubscriber implements SubscriberInterface
{
    private $pluginName;
    private $pluginDirectory;
    private $randomProduct;
    private $config;

    public function __construct(
    $pluginName, 
    $pluginDirectory,
    RandomProduct $randomProduct,
    $config
    )
    {
        $this->pluginName = $pluginName;
        $this->pluginDirectory = $pluginDirectory;
        $this->randomProduct = $randomProduct;
        $this->config = $config;
    }
