I want to instantiate CatalogInventory model in Magento 2 by calling loadByProduct() just like I used to do in Magento 1:

$stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product);

How can I do this or similar in Magento2?

UPDATED ANSWER:

I have tried getting the stock of a product this way:

 use Magento\CatalogInventory\Api\Data\StockItemInterface;
 use Magento\CatalogInventory\Model\ResourceModel\Stock\Item;

 $model = $this->_objectManager->create('Magento\CatalogInventory\Model\ResourceModel\Stock\Item');
 $stock=$model->loadByProductId(StockItemInterface $item, $productId, $stockId);

But I get,

Parse error: syntax error, unexpected '$item' (T_VARIABLE)

Look at vendor/magento/module-catalog-inventory/Model/ResourceModel/Stock/Item.php. As we can see, we can use an alternative method loadByProductId(). Navigate to vendor/magento/magento2-base/dev/tests/api-functional/testsuite/Magento/CatalogInventory/Api/StockItemTest.php to see the testing.

        $productId = 123456;
        $stockId = 2334;
        /** @var \Magento\CatalogInventory\Api\Data\StockItemInterfaceFactory $stockItemFactory */
        $stockItemFactory = $this->objectManager->get('Magento\CatalogInventory\Api\Data\StockItemInterfaceFactory');
        $stockItem = $stockItemFactory->create();
        /** @var \Magento\CatalogInventory\Model\ResourceModel\Stock\Item $stockItemResource */
        $stockItemResource = $this->objectManager->get('Magento\CatalogInventory\Model\ResourceModel\Stock\Item');
        $stockItemResource->loadByProductId($stockItem, $productId, $stockId);

You can simple get total stock of configurable products using objectManager.

$_product = $block->getProduct();
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$StockState = $objectManager->get('\Magento\CatalogInventory\Api\StockStateInterface');
$total_stock = 0;
if($_product->getTypeID() == 'configurable'){
    $productTypeInstance = $_product->getTypeInstance();
    $usedProducts = $productTypeInstance->getUsedProducts($_product);
    foreach ($usedProducts as $simple) {
        $total_stock += $StockState->getStockQty($simple->getId(), $simple->getStore()->getWebsiteId());
    }
}
echo $total_stock;

Thanks
