Extending Product in Spartacus /How to add custom attribute in Product in SAP Spartacus?

 In this example, I will add  manufacturAid attribute which does not exist in OOB ProductData/ProductWSDTO class

A. Update Your XXXXws-beans.xml file to add below entries.

 1. Add bean definition to add additional field on OOB ProductData

 <bean class="de.hybris.platform.commercefacades.product.data.ProductData">

   <property name="manufacturerAid" type="java.lang.String">
      <description>MFG Part#</description>
   </property>
</bean>
2. Add bean definition to add additional field on OOB ProductWsDTO
<bean class="de.hybris.platform.commercewebservicescommons.dto.product.ProductWsDTO" >
   <property name="manufacturerAid" type="java.lang.String">
      <description>MFG Part#</description>
   </property>

</bean>


B. update field mapping in dto-level-mappings-v2-spring.xml file

<bean parent="fieldSetLevelMapping" id="productWsDTOFieldSetLevelMapping">
    <property name="dtoClass"
              value="de.hybris.platform.commercewebservicescommons.dto.product.ProductWsDTO"/>
    <property name="levelMapping">
        <map>
            <entry key="BASIC"
                   value="purchasable,stock,name,baseProduct,availableForPickup,
                   code,url,price"/>
            <entry key="DEFAULT"
                   value="summary,averageRating,purchasable,stock(DEFAULT),
                  description,variantMatrix(DEFAULT),name,baseOptions(DEFAULT),
                  baseProduct,availableForPickup,variantOptions(DEFAULT),code,
                  url,price(DEFAULT),numberOfReviews,manufacturer,
                 categories(BASIC,name),priceRange,multidimensional,configuratorType,
                 configurable,tags,manufacturerAid"/>
            <entry key="FULL"
                   value="summary,productReferences(FULL),classifications(FULL),averageRating,purchasable,
                 volumePrices(FULL),variantType,stock(FULL),description,variantMatrix(FULL),name,baseOptions(FULL),baseProduct,availableForPickup,variantOptions(FULL),reviews(FULL),code,url,price(FULL),numberOfReviews,manufacturer,volumePricesFlag,futureStocks(FULL),images(FULL),categories(FULL),potentialPromotions(FULL),priceRange,
                multidimensional,configuratorType,configurable,
                 tags,manufacturerAid"/>
        </map>
    </property>
</bean>


C. create custom populator to populate  manufacturerAid Field.
here we are extending OOB ProductPopulator

package com.bdi.test.facades.populator;



import de.hybris.platform.commercefacades.product.converters.populator.ProductPopulator;
import de.hybris.platform.commercefacades.product.data.ProductData;
import de.hybris.platform.core.model.product.ProductModel;

import javax.annotation.Resource;

public class TestWSProductPopulator extends  ProductPopulator {

  

    @Override
    public void populate(final ProductModel source, final ProductData target)
    {
      super.populate(source, target);
     
      target.setManufacturerAid("Test-MFGID");
    }

}


D. override OOB Product populator to use custom populator.

  This change needs to add in xxxws-spring.xml file.
<alias name="bdiWSProductPopulator" alias="productPopulator"/>
<bean id="bdiWSProductPopulator" class="com.bdi.newexpress.facades.populator.TestWSProductPopulator"
     parent="defaultProductPopulator">

</bean>

Emma's dream - a kids story - By Kavya

Emma's Dream Emma was in her marshmallow themed bed, she had hoped to get a great dream tonight. “Good night Emma” said her mom. “Good night mom!” she said as she was about to fall asleep. In her dream she found herself surrounded by candy, cotton candy clouds, lollipop trees, a chocolate river and gumdrop rocks! She already knew this was going to be the best dream ever!  Then she heard something, it was a sound coming from the bushes. “Who is there? "she said.
