It's possible to custom the mapper for ClassData and ClassWsDTO - Hybris - YCommerceWebServices

Question

I have an object in my data class and I want only a specific attribute of this object in the WsDTO class.

Declaration of custom B2BUnitData

<bean class="de.hybris.platform.b2bcommercefacades.company.data.B2BUnitData">
 <property name="PointOfServiceData"
 type="de.hybris.platform.commercefacades.storelocator.data.PointOfServiceData"/>
</bean>

Declaration of B2bUnitWsDTO

<bean class="de.hybris.platform.b2boccaddon.dto.b2bunit.B2bUnitWsDTO">
    <property name="PointOfServiceData" type="PointOfServiceWsDTO" />
</bean>

file : dto-level-mappings-v2-spring.xml

 <bean parent="fieldSetLevelMapping" id="b2bunitWsDTOFieldSetLevelMapping">
    <property name="dtoClass"
              value="de.hybris.platform.b2boccaddon.dto.pricerow.B2bUnitWsDTO"/>
    <property name="levelMapping">
        <map>
            <entry key="FULL" value="PointOfServiceData" />
        </map>
    </property>
</bean>

this implementation give me all the object pointOfService but I only want the UID attribute in the B2bUnitWsDTO

The only solution I know, will be to create a PointOfServiceUID attribute in the data and map it directly in the b2bunitWsDTOFieldSetLevelMapping bean.

I would know if it's possible to map in the dto-level-mappings-v2-spring.xml only one attribute of my object :

Exemple :

Or if it exist some solution to do that

As you already mentioned, you could change the dto-level-mappings-v2-spring.xml so that for all levels (BASIC, DEFAULT, FULL) only the uid is returned.

<bean parent="fieldSetLevelMapping" id="b2bunitWsDTOFieldSetLevelMapping">
    <property name="dtoClass"
              value="de.hybris.platform.b2boccaddon.dto.pricerow.B2bUnitWsDTO"/>
    <property name="levelMapping">
        <map>
            <entry key="BASIC" value="PointOfServiceData(uid)" />
            <entry key="DEFAULT" value="PointOfServiceData(uid)" />
            <entry key="FULL" value="PointOfServiceData(uid)" />
        </map>
    </property>
</bean>

Beware, the fieldSetLevelMapping beans only define how your response looks like!

If you want to change how a B2BUnitData is mapped to a B2bUnitWsDTO, you have to define a custom field mapper (you can find examples in dto-mappings-v2-spring.xml)

Assuming your B2bUnitWsDTO now only has pointOfServiceUID as property, this may look like this (disclaimer: you need to test this):

    <bean id="b2bUnitFieldMapper" parent="fieldMapper">
    <property name="sourceClass"
              value="de.hybris.platform.b2bcommercefacades.company.data.B2BUnitData"/>
    <property name="destClass"
              value="com.customer.some.package.B2bUnitWsDTO"/>
    <property name="fieldMapping">
        <map>
            <entry key="PointOfServiceData.uid" value="pointOfServiceUID"/>
        </map>
    </property>
</bean>
