come magento sta ottenendo il prezzo più basso del prodotto configurabile dei prodotti associati?

Nella pagina di visualizzazione per impostazione predefinita magento mostra il prezzo più basso dei prodotti associati.

Devo visualizzare il prezzo più alto dei prodotti associati. Qualcuno ha idea di dove risieda la logica. Come personalizzare questo comportamento.

aggiornare:

Magento \ ConfigurableProduct \ Pricing \ Prezzo \ ConfigurablePriceResolver

/**
     * @param \Magento\Framework\Pricing\SaleableInterface|\Magento\Catalog\Model\Product $product
     * @return float
     * @throws \Magento\Framework\Exception\LocalizedException
     */
    public function resolvePrice(\Magento\Framework\Pricing\SaleableInterface $product)
    {
        $price = null;
        foreach ($this->configurable->getUsedProducts($product) as $subProduct) {
            $productPrice = $this->priceResolver->resolvePrice($subProduct);
            $price = $price ? min($price, $productPrice) : $productPrice;
        }
        if (!$price) {
            throw new \Magento\Framework\Exception\LocalizedException(
                __('Configurable product "%1" do not have sub-products', $product->getName())
            );
        }
        return (float)$price;
    }

Sto cercando di sovrascrivere questo file core, ma non funziona.

<?php
namespace Kensium\Catalog\Pricing\Price;
class ConfigurablePriceResolver extends \Magento\ConfigurableProduct\Pricing\Price\ConfigurablePriceResolver
{
    /**

     * @return float
     * @throws \Magento\Framework\Exception\LocalizedException
     */
    public function resolvePrice(\Magento\Framework\Pricing\SaleableInterface $product)
    {
        $price = null;       
        $assPrice=array();
        foreach ($this->configurable->getUsedProducts($product) as $subProduct) {
            $productPrice = $this->priceResolver->resolvePrice($subProduct);
            $assPrice[]=$productPrice;
            $price = $price ? min($price, $productPrice) : $productPrice;
        }
        if (!$price) {
            throw new \Magento\Framework\Exception\LocalizedException(
                __('Configurable product "%1" do not have sub-products', $product->getName())
            );
        }
        return (float)(max($assPrice));
        //return (float)$price;
    }
}

Devi creare un plug-in per visualizzare il prezzo massimo nella pagina dei dettagli, di seguito è riportato il modulo passo passo per le tue esigenze,

All'interno di questo file, devi pluginize la funzione resolprice ()

Vedere \Magento\ConfigurableProduct\Pricing\Price\ConfigurablePriceResolver::resolvePrice. È il metodo resposible per il calcolo del prezzo del prodotto configurabile basato sul prezzo secondario.

Puoi plug-in e implementare il tuo algoritmo.
