Advanced Configurations of OCC Webservices in SAP Commerce 2211 Using YOCC Template – Part 2

Go to Part 1 OCC: OCC Webservices in SAP Commerce (Hybris) 2211 – Part 1

Step 11:

In this step, you are adding a bean definition for B2CStoreDataList in samplefacades-beans.xml This bean will hold a list of B2CStoreData objects, which are returned by passing a storeId.

Location:/samplefacades/resources/samplefacades-beans.xml

<bean class="com.hybris.simple.facades.B2CStoreDataList">
    <property name="b2cstore" type="java.util.List<com.hybris.simple.facades.B2CStoreData>" />
</bean>

Step 12:

In this step, we will create the B2CStorePopulator to map data from the SampleB2CStoreModel to B2CStoreData.

Location: /samplefacades/src/com/hybris/simple/facades/populators/B2CStorePopulator.java

import de.hybris.platform.converters.Populator;
import de.hybris.platform.servicelayer.dto.converter.ConversionException;
import com.hybris.simple.core.model.SampleB2CStoreModel

; import com.hybris.simple.facades.B2CStoreData; public class B2CStorePopulator implements Populator<SampleB2CStoreModel,B2CStoreData> { @Override public void populate(SampleB2CStoreModel source, B2CStoreData target) throws ConversionException { target.setStoreId(source.getStoreId()); target.setStoreName(source.getStoreName()); target.setStoreLocation(source.getStoreLocation()); target.setStoreGstNumber(source.getStoreGstNumber()); target.setStoreOwner(source.getStoreOwner()); } }
Step 13:

In this step, we will configure the b2CSampleStoreConverter and b2CStorePopulator in the samplecore-spring.xml file.

Location:/samplecore/resources/samplecore-spring.xml

Converter: The converter contains a chain of populators and uses populators to convert data from the source to the target. It creates new instances of Data objects.

Populator: The populator fills the data object by getting the data from the model.

<alias name="b2CSampleStoreConverter" alias="b2CStoreConverter" />
<bean id="b2CSampleStoreConverter" parent="abstractPopulatingConverter">
<property name="targetClass" value="com.hybris.simple.facades.B2CStoreData"/>
    <property name="populators">
        <list merge="true">
            <ref bean="b2CStorePopulator" />
        </list>
    </property>
</bean>

<bean id="b2CStorePopulator" class="com.hybris.simple.facades.populators.B2CStorePopulator" />

Step 14:

In this step, we will implement the DefaultB2CStoreFacade class, which provides the actual logic for fetching store details using the B2CStoreFacade interface.

Location: /samplecore/src/com/hybris/simple/facades/b2cstore/facade/impl/DefaultB2CStoreFacade.java

package com.hybris.simple.facades.b2cstore.facade.impl;
import de.hybris.platform.converters.impl.AbstractPopulatingConverter;
import java.util.Collections;
import java.util.List;
import javax.annotation.Resource;
import org.apache.commons.collections.CollectionUtils;
import com.hybris.simple.b2cstore.service.B2CStoreService;
import com.hybris.simple.core.model.SampleB2CStoreModel;
import com.hybris.simple.facades.B2CStoreData;
import com.hybris.simple.facades.b2cstore.facade.B2CStoreFacade;
public class DefaultB2CStoreFacade implements B2CStoreFacade {

    @Resource
    AbstractPopulatingConverter  b2CStoreConverter;

    @Resource
    private B2CStoreService b2CStoreService;

    @Override
    public List<B2CStoreData> getB2CStoreDetailsById(final String storeId) {
        List b2CStoreModels = b2CStoreService.getB2CStoreDetailsById(storeId);
        return CollectionUtils.isNotEmpty(b2CStoreModels) ? b2CStoreConverter.convertAll(b2CStoreModels) : Collections.emptyList();
    }

}
  

Step 15: Configure the DefaultB2CStoreFacade in samplefacades-spring.xml
Location: /samplefacades/resources/samplefacades-spring.xml

<alias name="defaultB2CStoreFacade" alias="b2cStoreFacade" />
<bean id="defaultB2CStoreFacade" class="com.hybris.simple.facades.b2cstore.facade.impl.DefaultB2CStoreFacade" />

Step 16: Configure the B2CStoreDataWSDTO bean in sampleocc-beans.xml
Location: /sampleocc/resources/sampleocc-beans.xml

<bean class="com.hybris.simple.facades.B2CStoreDataWSDTO">
    <property name="storeId" type="String" />
    <property name="storeName" type="String" />
    <property name="storeLocation" type="String" />
    <property name="storeOwner" type="String" />
    <property name="storeGstNumber" type="String" />
</bean>
  

Step 17: Do ant all in platform, After the build completes, verify that the B2CStoreDataWSDTO.java file is generated or not.

Step 18:

Configure the B2CStoreDataListWSDTO bean in sampleocc-beans.xml. This bean holds a list of B2CStoreDataWSDTO objects.

Location: /sampleocc/resources/sampleocc-beans.xml

<bean class="com.hybris.simple.facades.B2CStoreDataListWSDTO">
    <property name="b2cstore" 
        type="java.util.List<com.hybris.simple.facades.B2CStoreDataWSDTO>" />
</bean>
  

Step 19:

Create the SampleB2CStoreController in the com.hybris.occ.controllers package. This controller defines an endpoint to fetch B2C Store details by storeId.

Location: /sampleocc/src/com/hybris/occ/controllers/SampleB2CStoreController.java

package com.hybris.occ.controllers;

import de.hybris.platform.webservicescommons.mapping.DataMapper;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

@Controller
@RequestMapping(value = "/{baseSiteId}")
public class SampleB2CStoreController {
    @Resource
    private B2CStoreFacade b2cStoreFacade;

    @Resource
    private DataMapper dataMapper;

    @RequestMapping(value = "/{storeId}", method = RequestMethod.GET)
    @ResponseBody
    public B2CStoreDataListWSDTO getb2CStoreDetailsById(
            @PathVariable final String storeId,
            @RequestParam(defaultValue = "DEFAULT") final String fields) {
        if (storeId == null || storeId.trim().isEmpty()) {
            return new B2CStoreDataListWSDTO();
        }
        B2CStoreDataList b2CStoreDataList = new B2CStoreDataList();
        b2CStoreDataList.setB2cstore(b2cStoreFacade.getB2CStoreDetailsById(storeId));
        return dataMapper.map(b2CStoreDataList, B2CStoreDataListWSDTO.class, fields);
    }
}
  

Step 20:

This step involves adding the configuration for b2CStoreFieldMapper in the sampleocc-web-spring.xml file. Define fieldmapper to map fields between B2CStoreData and B2CStoreDataWSDTO.

Location: /sampleocc/resources/occ/v2/sampleocc/web/spring/sampleocc-web-spring.xml

<bean id="b2CStoreFieldMapper" parent="fieldMapper">
    <property name="sourceClass" value="com.hybris.simple.facades.B2CStoreData" />
    <property name="destClass" value="com.hybris.simple.facades.B2CStoreDataWSDTO" />
</bean>

Step 21: Adding FieldSet Level Mappings

In this sampleocc-web-spring.xml, the B2CStoreDataWSDTOis used to represent a single store, while the B2CStoreDataListWSDTO is used to represent a collection of stores. The level mappings define the different fields that should be included based on the request level (BASIC, DEFAULT, FULL).

Location: /sampleocc/resources/occ/v2/sampleocc/web/spring/sampleocc-web-spring.xml

<bean parent="fieldSetLevelMapping" id="b2CStoreDataWSDTOFieldSetLevelMapping">
    <property name="dtoClass" value="com.hybris.simple.facades.B2CStoreDataWSDTO" />
    <property name="levelMapping">
        <map>
            <entry key="BASIC" value="storeId,storeName" />
            <entry key="DEFAULT" value="storeId,storeName,storeOwner" />
            <entry key="FULL" value="storeId,storeName,storeOwner,storeLocation,storeGstNumber" />
        </map>
    </property>
</bean>

<bean parent="fieldSetLevelMapping" id="b2CStoreDataListWSDTOFieldSetLevelMapping">
    <property name="dtoClass" value="com.hybris.simple.facades.B2CStoreDataListWSDTO" />
    <property name="levelMapping">
        <map>
            <entry key="BASIC" value="b2cstore(BASIC)"/>
            <entry key="DEFAULT" value="b2cstore(DEFAULT)"/>
            <entry key="FULL" value="b2cstore(FULL)"/>
        </map>
    </property>
</bean>
  

Step 22: Do ant all in platform, After the build completes,make hybris server up.Add some storeId through backoffice or Impex
Pass the storeId and fields like BASIC,FULL,DEFAULT
