1.创建一个简单商品

首先，您必须构建产品模型，以便为新产品设置数据

/**

* @var \Magento\Catalog\Model\ProductFactory

*/

protected $_productFactory;

/**

* @var \Magento\Catalog\Model\ResourceModel\Product

*/

protected $_resourceModel;

/**

* @var SourceItemInterface

*/

protected $sourceItemsSaveInterface;

/**

* @var \Magento\InventoryApi\Api\Data\SourceItemInterfaceFactory

*/

protected $sourceItem;

/**

* @var \Magento\Eav\Api\AttributeRepositoryInterface

*/

protected $attributeRepository;

/**

* @var \Magento\ConfigurableProduct\Helper\Product\Options\Factory

*/

protected $_optionsFactory;

/**

* @var \Magento\Catalog\Api\ProductRepositoryInterface

*/

protected $productRepository;

/**

* @var \Magento\Catalog\Setup\CategorySetup

*/

protected $categorySetup;

/**

* Index constructor.

* @param \Magento\Catalog\Model\ProductFactory $productFactory

* @param \Magento\Catalog\Model\ResourceModel\Product $resourceModel

* @param SourceItemInterface $sourceItemsSaveInterface

* @param \Magento\InventoryApi\Api\Data\SourceItemInterfaceFactory $sourceItem

* @param \Magento\Eav\Api\AttributeRepositoryInterface $attributeRepository

* @param \Magento\ConfigurableProduct\Helper\Product\Options\Factory $optionsFactory

* @param \Magento\Catalog\Api\ProductRepositoryInterface $productRepository

* @param \Magento\Catalog\Setup\CategorySetup $categorySetup

* @param Context $context

*/

public function __construct(

   \Magento\Catalog\Model\ProductFactory $productFactory,

   \Magento\Catalog\Model\ResourceModel\Product $resourceModel,

   \Magento\InventoryApi\Api\Data\SourceItemInterface $sourceItemsSaveInterface,

   \Magento\InventoryApi\Api\Data\SourceItemInterfaceFactory $sourceItem,

   \Magento\Eav\Api\AttributeRepositoryInterface $attributeRepository,

   \Magento\ConfigurableProduct\Helper\Product\Options\Factory $optionsFactory,

   \Magento\Catalog\Api\ProductRepositoryInterface $productRepository,

   \Magento\Catalog\Setup\CategorySetup $categorySetup,

   Context $context

) {

   parent::__construct($context);

   $this->_productFactory = $productFactory;

   $this->_resourceModel = $resourceModel;

   $this->sourceItemsSaveInterface = $sourceItemsSaveInterface;

   $this->sourceItem = $sourceItem;

   $this->attributeRepository = $attributeRepository;

   $this->_optionsFactory = $optionsFactory;

   $this->productRepository = $productRepository;

   $this->categorySetup = $categorySetup;

}

/**

* @return \Magento\Framework\App\ResponseInterface|\Magento\Framework\Controller\ResultInterface|void

* @throws \Magento\Framework\Exception\NoSuchEntityException

*/

public function execute()

{

   $product = $this->_productFactory->create();

   $colorAttr = $this->attributeRepository->get(Product::ENTITY, 'color');

   $bottomSetId =$this->categorySetup->getAttributeSetId(Product::ENTITY, 'Bottom');

   $associatedProductIds = [];

   $options = $colorAttr->getOptions();

   $values = [];

   $sourceItems = [];

   array_shift($options);

   try {

       //Create Simple product

       foreach ($options as $index => $option) {

           $product->unsetData();

           $product->setTypeId(Type::TYPE_SIMPLE)

               ->setAttributeSetId($bottomSetId)

               ->setWebsiteIds([1])

               ->setName('Sample-' . $option->getLabel())

               ->setSku('simple_' . $index)

               ->setPrice(10)

               ->setVisibility(Visibility::VISIBILITY_NOT_VISIBLE)

               ->setStatus(Status::STATUS_ENABLED);

           $product->setCustomAttribute(

               $colorAttr->getAttributeCode(),

               $option->getValue()

           );

           $this->_resourceModel->save($product);

           // Update Stock Data

           $sourceItem = $this->sourceItem->create();

           $sourceItem->setSourceCode(null);

           $sourceItem->setSourceCode('default');

           $sourceItem->setQuantity(10);

           $sourceItem->setSku($product->getSku());

           $sourceItem->setStatus(SourceItemInterface::STATUS_IN_STOCK);

           $sourceItems[] = $sourceItem;

           $values[] = [

               "value_index" => $option->getValue(),

           ];

           $associatedProductIds[] = $product->getId();

       }

       //Execute Update Stock Data

       $this->sourceItemsSaveInterface->execute($sourceItems);

2.创建可配置商品

//Create Configurable Product
$configurable = $product->unsetData();
$configurable->setSku('sample_configurable');
$configurable->setName('Sample Configurable');
$configurable->setTypeId(Configurable::TYPE_CODE);
$configurable->setPrice(10);
$configurable->setAttributeSetId($this->categorySetup->getAttributeSetId(Product::ENTITY, 'Default'));
$configurable->setCustomAttributes([
   [
       "attribute_code" => $colorAttr->getAttributeCode(),
       "value" => $colorAttr->getDefaultValue(),
   ],
]);

3. 给可配置商品分配简单商品

//Assign simple products to the configurable product
$extensionAttrs = $configurable->getExtensionAttributes();
$extensionAttrs->setConfigurableProductLinks($associatedProductIds);
$optionsFact = $this->_optionsFactory->create([
   [
       "attribute_id" => $colorAttr->getId(),
       "label" => $colorAttr->getDefaultFrontendLabel(),
       "position" => 0,
       "values" => $values,
   ]
]);
$extensionAttrs->setConfigurableProductOptions($optionsFact);
$configurable->setExtensionAttributes($extensionAttrs);

$this->productRepository->save($configurable);
