레지스트리를 사용하지 않고 현재 제품 가져오기 - Magento 2

우리는 현재 제품을 얻기 위해 Magento 레지스트리 방법을 사용하고 있습니다. 그러나 레지스트리 방법은 더 이상 사용되지 않습니다. 따라서 다음은 해결 방법입니다.

모델 또는 블록에서 다음 방법을 사용하여 현재 제품을 호출할 수 있습니다.

예: 블록:

Paboda/Catalog/Block/Product.php

<?php
namespace Paboda\Catalog\Block;

use Magento\Framework\View\Element\Template;
use Paboda\Catalog\Registry\CurrentProduct;

class Product extends Template
{
    /**
     * @var CurrentProduct
     */
    protected $currentProduct;

    private $product;

    /**
     * Attachments constructor.
     *
     * @param Template\Context $context
     * @param CurrentProduct $currentProduct
     * @param array $data
     */
    public function __construct(
        Template\Context $context,
        CurrentProduct $currentProduct,
        array $data = []
    ) {
        $this->currentProduct = $currentProduct;
        parent::__construct($context, $data);
    }

    /**
     * Get product
     *
     * @return array
     * @throws \Magento\Framework\Exception\NoSuchEntityException
     */
    public function getCurrentProduct()
    {
        return $this->currentProduct->get();
    }
}
