我正在开发 Shopware 6 插件。

<?php declare(strict_types=1);

namespace ReCachePlugin\Listener;


use Shopware\Core\Framework\DataAbstractionLayer\Pricing\Price;
use Shopware\Core\Framework\DataAbstractionLayer\Event\EntityLoadedEvent;




class ProductLoadedListener{


    public function onProductLoaded(EntityLoadedEvent $entityLoadedEvent){
        
        print_r($entityLoadedEvent->getIds()); 
        print_r($price->getNet());
    

    }

}

下面是我的 services.xml 文件

<container xmlns="http://symfony.com/schema/dic/services"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">

    <services>
        
        <service id="ReCachePlugin\Listener\ProductLoadedListener" >
            <tag  name="kernel.event_listener" event="product.loaded" />
        </service>

    </services>
</container>

这可行print_r($entityLoadedEvent->getIds());，但这print_r($price->getNet());不起作用我尝试在类$price = new Price内部和外部实例化类，ProductLoadedListener但我得到了错误。

那我该如何让它print_r($price->getNet());工作呢？
