Order Submit Workflow For Heat Clinic Tutorial

NOTE: This tutorial requires you to complete the Extending Customer For Heat Clinic Tutorial first.

Hooking into the submit order workflow

First, let's look at the default checkout workflow provided by broadleaf:

    <bean p:order="1000" id="blVerifyCustomerMaxOfferUsesActivity" class="org.broadleafcommerce.core.offer.service.workflow.VerifyCustomerMaxOfferUsesActivity"/>
    <bean p:order="2000" id="blValidateProductOptionsActivity" class="org.broadleafcommerce.core.checkout.service.workflow.ValidateProductOptionsActivity"/>
    <bean p:order="3000" id="blValidateAndConfirmPaymentActivity" class="org.broadleafcommerce.core.checkout.service.workflow.ValidateAndConfirmPaymentActivity">
        <property name="rollbackHandler" ref="blConfirmPaymentsRollbackHandler" />
    </bean>
    <bean p:order="4000" id="blRecordOfferUsageActivity" class="org.broadleafcommerce.core.offer.service.workflow.RecordOfferUsageActivity">
        <property name="rollbackHandler" ref="blRecordOfferUsageRollbackHandler" />
    </bean>
    <bean p:order="5000" id="blCommitTaxActivity" class="org.broadleafcommerce.core.checkout.service.workflow.CommitTaxActivity">
        <property name="rollbackHandler" ref="blCommitTaxRollbackHandler" />
    </bean>
    <bean p:order="6000" id="blCompleteOrderActivity" class="org.broadleafcommerce.core.checkout.service.workflow.CompleteOrderActivity">
        <property name="rollbackHandler" ref="blCompleteOrderRollbackHandler" />
    </bean>

    <bean id="blCheckoutWorkflow" class="org.broadleafcommerce.core.workflow.SequenceProcessor">
        <property name="processContextFactory">
            <bean class="org.broadleafcommerce.core.checkout.service.workflow.CheckoutProcessContextFactory"/>
        </property>
        <property name="activities">
            <list>
                <ref bean="blVerifyCustomerMaxOfferUsesActivity" />
                <ref bean="blValidateProductOptionsActivity" />
                <ref bean="blValidateAndConfirmPaymentActivity" />
                <ref bean="blRecordOfferUsageActivity" />
                <ref bean="blCommitTaxActivity" />
                <ref bean="blCompleteOrderActivity" />
            </list>
        </property>
        <property name="defaultErrorHandler" ref="blDefaultErrorHandler"/>
    </bean>

This is a copy of the default workflow. You can find the default workflows in the following place in the Broadleaf codebase: core/broadleaf-framework/src/main/resources/bl-framework-applicationContext-workflow.xml

Create a new activity

We need to add a new activity to record the average heat level for a given customer. Let's create that activity. In the site project, we'll create RecordHeatRangeActivity.java in the com.mycompany.checkout.service.workflow package with the following contents:

public class RecordHeatRangeActivity extends BaseActivity {
    private static final Log LOG = LogFactory.getLog(RecordHeatRangeActivity.class);

    @Resource(name = "blCustomerService")
    protected CustomerService customerService;

    @Override
    public ProcessContext execute(ProcessContext context) throws Exception {
        CheckoutSeed seed = (CheckoutSeed) context.getSeedData();
        Order order = seed.getOrder();
        int orderTotalHeatRating = 0;
        int productCount = 0;

        for (DiscreteOrderItem doi : order.getDiscreteOrderItems()) {
            ProductAttribute heatRating = doi.getProduct().getProductAttributes().get("heatRange");
            try {
                orderTotalHeatRating += (doi.getQuantity() * Integer.parseInt(heatRating.getValue()));
                productCount += doi.getQuantity();
            } catch (Exception e) {
                LOG.warn("Unable to parse the heat range. Product id: " + doi.getProduct().getId());
            }
        }

        HCCustomer customer = (HCCustomer) CustomerState.getCustomer();
        customer.setNumSaucesBought(customer.getNumSaucesBought() + productCount);
        customer.setTotalHeatRating(customer.getTotalHeatRating() + orderTotalHeatRating);
        customer = (HCCustomer) customerService.saveCustomer(customer);
        CustomerState.setCustomer(customer);

        return context;
    }
}

Note: You should choose org.broadleafcommerce.core.order.domain.Order, org.apache.common.logging.Log, and org.apache.common.logging.LogFactory as imports.

Notice that the activity loops through all current products in the order and assigns the appropriate heat range to the customer.

Add our activity to the workflow

We want to add our new activity between the RecordOfferUsageActivity and the CompleteOrderActivity.
In this example, within applicationContext.xml, we override the blCheckoutWorkflow and set the p:order="5500" in the bean declaration, like so:

    <bean id="blCheckoutWorkflow" class="org.broadleafcommerce.core.workflow.SequenceProcessor">
        <property name="activities">
            <list>
                <bean p:order="5500" class="com.mycompany.checkout.service.workflow.RecordHeatRangeActivity"/>
            </list>
        </property>
    </bean>

and our checkout workflow is complete. Check out the end result after checking out an order that had (1) level 6 sauce and (1) level 8 sauce:
