Hybris: Cannot create ProductBundle Item Type that extends ProductModel

I wanted to implement custom dynamic attribute handler class for ProductBundle class, but it expects AbstractItemModel type instead of my ProductBundle:

public class BundlePriceAttributeHandler extends AbstractDynamicAttributeHandler<Double, ProductModel> {

It gives error: type argument ProductModel is not within bounds of type-variable MODEL hybris

Then I tried

    <itemtype code="ProductBundle" autocreate="true" generate="true" extends="ProductModel">
        <attributes>
            <attribute qualifier="bundlePrice" type="java.lang.Double">
                <persistence type="dynamic" attributeHandler="bundlePriceAttributeHandler"/>
            </attribute>
        </attributes>
    </itemtype>

but, there is error YComposedType due to missing super type 'ProductModel' (even using de.hybris.platform.core.model.product.ProductModel)

if I try extend just "Product" my ProductBundle will extend just Product jalo class not ProductModel, and it will cause error: type argument ProductModel is not within bounds of type-variable MODEL hybris again.

Solution

  • As per this error

    YComposedType due to missing super type 'ProductModel' (even using de.hybris.platform.core.model.product.ProductModel)

    It is saying that type ProductModel is not available, and that's correct. This platform's default itemtype name is "product," not "ProductModel".

    Naming convention follows as below:

    enter image description here

    so correct entry should be as below.

    <itemtype code="ProductBundle" autocreate="true" generate="true" extends="Product">
                <attributes>
                    <attribute qualifier="bundlePrice" type="java.lang.Double">
                        <persistence type="dynamic" attributeHandler="bundlePriceAttributeHandler"/>
                    </attribute>
                </attributes>
            </itemtype>

    and attribute handler class :

    package com.customer.attributeHandler;

import com.core.model.ProductBundleModel;
import de.hybris.platform.servicelayer.model.attribute.DynamicAttributeHandler;

public class BundlePriceAttributeHandler implements DynamicAttributeHandler<Double, ProductBundleModel> {

    @Override
    public Double get(ProductBundleModel model) {
        //Random return
        return model.getAverageRating();
    }

    @Override
    public void set(ProductBundleModel model, Double aDouble) {

    }
}

    Bean entry as below:

    <alias name="bundlePriceAttributeHandler" alias="bundlePriceAttributeHandler"/>
    <bean class="com.customer.attributeHandler.BundlePriceAttributeHandler" id="bundlePriceAttributeHandler"/>
