Answer 1

Get Attribute Id By Attribute Code In Magento2.

Just you have to follow some steps.

Create constructor

/**
 * @var \Magento\Eav\Model\ResourceModel\Entity\Attribute
 */
protected $_eavAttribute;
/**
 * @param   Context                                           $context
 * @param   \Magento\Eav\Model\ResourceModel\Entity\Attribute $eavAttribute
 */
public function __construct(
    Context $context,
    \Magento\Eav\Model\ResourceModel\Entity\Attribute $eavAttribute
)
{
    $this->_eavAttribute = $eavAttribute;
    parent::__construct($context);
}

//Call the getIdByCode method of Attribute in any method.

//Your $this->_eavAttribute->getIdByCode('entity_type', 'attribute_code');

$attributeId = $this->_eavAttribute->getIdByCode('customer', 'company_name');

You can also use a product attribute repository class to do this:

public function __construct(
    \Magento\Catalog\Api\ProductAttributeRepositoryInterface $productAttributeRepository,
) {
    $this->productAttributeRepository = $productAttributeRepository;
}

public function example()
{

    $attribute = $this->productAttributeRepository->get('size');
    $sizeId = $attribute->getAttributeId();

}

Answer 3

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$entityAttribute = $objectManager->get('Magento\Eav\Model\ResourceModel\Entity\Attribute');
$attributeId = $entityAttribute->getIdByCode('ENTITY TYPE', 'ATTRIBUTE CODE');

for example, get the product attribute ID with the attribute code brand:

$attributeId = $entityAttribute->getIdByCode('catalog_product', 'brand');
