Inventory

This module provides basic inventory functions to Broadleaf. Some of the concepts provided here include:

• Inventory across multiple Fulfillment Locations - relevant for multi-warehouse scenarios. You can track inventory for a Sku across many locations
• Optimistic locking - while changing inventory, the system attempts to obtain an optimistic row lock on the Inventory object for that particular Sku. This is useful for high-volume website where you want to ensure
• Workflow activities - New activities are included for the update, add and checkout workflows. The only time the inventory is actually adjusted in the database is during checkout.

If you are including this module at the beginning of your project, simply switch to the inventory branch of DemoSite. All of the necessary changes are implemented there.

If you already have a site up and running from a vanilla version of DemoSite and would like to include inventory, here's how to get it integrated (most recent diff version of these instructions):

Get your Maven dependencies situated

In the root pom.xml of your project:

<dependency>
    <groupId>org.broadleafcommerce</groupId>
    <artifactId>broadleaf-inventory</artifactId>
    <version>1.0.0-SNAPSHOT</version>
</dependency>

Reference the dependency in both the admin and site pom.xmls:

<dependency>
    <groupId>org.broadleafcommerce</groupId>
    <artifactId>broadleaf-inventory</artifactId>
</dependency>

Ensure that the proper admin permissions are associated

depending on the current state of your database/import.sql files the primary keys might have to be changed:

INSERT INTO BLC_ADMIN_PERMISSION (ADMIN_PERMISSION_ID, DESCRIPTION, NAME, PERMISSION_TYPE) VALUES (69,'Create FulfillmentLocation','PERMISSION_CREATE_FULFILLMENT_LOCATION', 'CREATE');
INSERT INTO BLC_ADMIN_PERMISSION (ADMIN_PERMISSION_ID, DESCRIPTION, NAME, PERMISSION_TYPE) VALUES (70,'Update FulfillmentLocation','PERMISSION_UPDATE_FULFILLMENT_LOCATION', 'UPDATE');
INSERT INTO BLC_ADMIN_PERMISSION (ADMIN_PERMISSION_ID, DESCRIPTION, NAME, PERMISSION_TYPE) VALUES (71,'Delete FulfillmentLocation','PERMISSION_DELETE_FULFILLMENT_LOCATION', 'DELETE');

INSERT INTO BLC_ADMIN_PERMISSION (ADMIN_PERMISSION_ID, DESCRIPTION, NAME, PERMISSION_TYPE) VALUES (78,'All Inventory','PERMISSION_ALL_INVENTORY','ALL');

INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (230, 'org.broadleafcommerce.core.inventory.domain.FulfillmentLocation', 64);
INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (231, 'org.broadleafcommerce.core.inventory.domain.FulfillmentLocation', 65);
INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (232, 'org.broadleafcommerce.core.inventory.domain.FulfillmentLocation', 66);

INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (234, 'org.broadleafcommerce.core.inventory.domain.FulfillmentLocation', 68);
INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (235, 'org.broadleafcommerce.core.inventory.domain.Inventory', 69);

INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (237, 'org.broadleafcommerce.core.inventory.domain.Inventory', 71);
INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (238, 'org.broadleafcommerce.core.inventory.domain.Inventory', 72);
INSERT INTO BLC_ADMIN_PERMISSION_ENTITY (ADMIN_PERMISSION_ENTITY_ID, CEILING_ENTITY, ADMIN_PERMISSION_ID) VALUES (239, 'org.broadleafcommerce.core.inventory.domain.Inventory', 73);

-- ensure that super user and catalog maintainer can modify inventory
INSERT INTO BLC_ADMIN_ROLE_PERMISSION_XREF (ADMIN_ROLE_ID, ADMIN_PERMISSION_ID) VALUES (1,73);
INSERT INTO BLC_ADMIN_ROLE_PERMISSION_XREF (ADMIN_ROLE_ID, ADMIN_PERMISSION_ID) VALUES (2,73);
INSERT INTO BLC_ADMIN_ROLE_PERMISSION_XREF (ADMIN_ROLE_ID, ADMIN_PERMISSION_ID) VALUES (1,78);
INSERT INTO BLC_ADMIN_ROLE_PERMISSION_XREF (ADMIN_ROLE_ID, ADMIN_PERMISSION_ID) VALUES (2,78);

-- tell the admin it needs to load this section also and associate permissions
INSERT INTO BLC_ADMIN_SECTION (ADMIN_SECTION_ID, ADMIN_MODULE_ID, NAME, SECTION_KEY, URL, USE_DEFAULT_HANDLER) VALUES (15, 1, 'Inventory', 'Inventory', '/inventory', TRUE);
INSERT INTO BLC_ADMIN_SECTION_PERMISSION_XREF (ADMIN_SECTION_ID, ADMIN_PERMISSION_ID) VALUES (15,74);
INSERT INTO BLC_ADMIN_SECTION_PERMISSION_XREF (ADMIN_SECTION_ID, ADMIN_PERMISSION_ID) VALUES (15,75);

INSERT INTO BLC_ADMIN_SECTION_PERMISSION_XREF (ADMIN_SECTION_ID, ADMIN_PERMISSION_ID) VALUES (15,77);

Ensure the correct workflow activities are included and Hibernate knows about the new entities:

Modify the web.xml in both the site and admin projects (and combined if you're using it) and ensure that this applicationContext appears in the patchConfigLocations parameter:

classpath:/bl-inventory-applicationContext.xml

If you have made modifications any modifications to the update/add/checkout workflows, you will need to ensure that blUpdateItemWorkflow and blAddItemWorkflow include the CheckAvailabilityActivity:

...
<bean id="blAddItemWorkflow" class="org.broadleafcommerce.core.workflow.SequenceProcessor">
    ...
    <property name="activities">
        <list>
            <bean class="org.broadleafcommerce.core.order.service.workflow.add.ValidateAddRequestActivity"/>
            <bean class="org.broadleafcommerce.inventory.service.workflow.CheckAvailabilityActivity"/>
        ...

and the blCheckoutWorkflow includes the DecrementInventoryActivity and also uses the blInventoryCompensatingCheckoutErrorHandler:

<bean id="blCheckoutWorkflow" class="org.broadleafcommerce.core.workflow.SequenceProcessor">
    <property name="activities">
        <list>
            <bean class="org.broadleafcommerce.core.offer.service.workflow.VerifyCustomerMaxOfferUsesActivity"/>
            <bean class="org.broadleafcommerce.inventory.service.workflow.DecrementInventoryActivity"/>
        ...
    <property name="defaultErrorHandler" ref="blInventoryCompensatingCheckoutErrorHandler"/>

Include the admin GWT module to manage inventory In myCompanyAdmin.gwt.xml:

<inherits name="org.broadleafcommerce.inventory.admin.inventoryModule" />

And that's it! Other potential modifications might be to show a specific message when you try to add an item that doesn't have inventory. Check the diff to see what we did on DemoSite.
