Dynamic Attribute

The following example shows the configuration of the Dynamic Attribute in the items.xml file:

<itemtype code="Accommodation" autocreate="true" generate="true" jaloclass="de.hybris.platform.test.Accommodation">
<attributes>

<attribute type="java.lang.String" qualifier="daysHumanReadable">
<persistence type="dynamic" attributeHandler="accommodationDays" />
<modifiers read="true" write="false" />
</attribute>

</attributes>
</itemtype>

AccommodationDays.java

public class AccommodationDays implements DynamicAttributeHandler<String, AccommodationModel>
{

 @Override
 public String get(final AccommodationModel model)
 {
                String daysWord;
  final int days = model.getDays();
                if (days == 1)
                {
                       daysWord = "day";
                } 
                else
                {
                       daysWord = "days";
                }
                return days + " " + daysWord;
 }

 @Override
 public void set(final AccommodationModel model, final String value)
 {
  throw new UnsupportedOperationException();
 }

}

It is recommended to implement the above method to throw an exception, because the write modifier of the daysHumanReadable attribute is set to false. Thus there is no setter generated in the AccommodationModel.

we can get the value based on some business logic.

base.properties
mycompany.select.termsandconditions = <span class="checkbox-text ma-label-font">I confirm that the information I have provided is accurate, and I agree to Mycompany <a class="a-link" target="_blank" href="https://www.mycompany.govt.nz/Pages/terms-and-conditions.aspx"> terms and conditions </a> and <a class="a-link" target="_blank" href="https://www.mycompany.govt.nz/Pages/privacy-policy.aspx"> privacy policy</a>. </span>

2) How to add Dynamic parameters
jsp:
<spring:theme code="mycompany.property.invalid.attempts.count.max.message" arguments="${jalosession.tenant.config.getParameter('mycompany.max.failed.attempts.count')} ,${jalosession.tenant.config.getParameter('mycompany.max.failed.attempts.hour')}" htmlEscape="false"></spring:theme>

base.properties

mycompany.property.invalid.attempts.count.max.message=<h5 class="ma-h5"> Account locked</h5><p>You have entered the incorrect number and PIN combination {0} times. You will not be able to add another property for {1} hours.</p>

3) How to read property key in jsp

<spring:theme code="mycompany.property.invalid.attempts.count.max.message" arguments="${jalosession.tenant.config.getParameter('mycompany.max.failed.attempts.count')} ,${jalosession.tenant.config.getParameter('mycompany.max.failed.attempts.hour')}" htmlEscape="false"></spring:theme>

mycompany.max.failed.attempts.count key defined in project.properties or base.properties

4) How to check anonymous customer in jsp
jalosession.attributes['user'].anonymousCustomer

5) Delete typecode from deployment table - same typecode for multiple items ( old one removed but still in deployment table)

DELETE FROM <YOUR DB NAME>.ydeployments WHERE Typecode=18001(deployment code);

change the development code what ever you have conflicts in my case its 18001 is the conflicting deployment code.

SAP Hybris ServiceLayer Architecture

Service Layer Architecture

The ServiceLayer can be described as a layer of services on top of the persistence layer. The services themselves can be divided into subcomponents.

Components

Client

A client in this context is any software component that uses the ServiceLayer, such as:

Page Controllers of an MVC framework
Web Service clients
Scripts
Other services

Services

A service holds the logic to perform business processes and provides this logic through a number of related public methods. These public methods usually are defined in a Java interface. Most often these methods operate on the same kind of model object, for example product, order, and so on.

Services are expected to abstract from the persistence layer, that is, to only contain functional logic and no persistence-related code. That means if you implement a service, make sure to implement it in a way that the underlying implementation is as loosely coupled to the persistence layer as possible.

SAP Hybris Commerce exposes all of its functionality through services. The following kinds of services are available:

Business Services implement business use cases, such as cart handling or back order.

Infrastructure Services provide the underlying technical foundation, such as internationalization, import, export, and so on.

System services provide functionality required by the ServiceLayer, such as model handling and session handling.

The service methods should be as fine-grained as possible to enable reuse.

Extensions must provide their functionality as services. Per extension you may provide as many services as you deem necessary, not just one.

Services may use other services to perform their tasks but should keep their inter dependencies to a minimum to avoid overly tight coupling with other components.

In a project, you may write your own services to either provide unique functionality or to aggregate other services' functionality.

Although technically not necessary, Hybris recommends implementing services in terms of interfaces.

Services interact with other components through models.

Strategies

A service may delegate parts of its tasks to smaller micro-services, called strategies. The service then serves as a kind of facade to the strategies. Clients still use the service and its stable API. But under the hood the functionality is split into multiple parts. Because these parts are smaller and very focused to their task, it is easier to adapt or replace them. Strategies therefore help to further encapsulate behavior and make it more adaptable.

DAOs

A DAO (Data Access Object) is an interface to the storage back end system. DAOs store and retrieve objects. You use DAOs to save, remove, and find models. DAOs are the place to put SQL or FlexibleSearch statements and nowhere else. This is to ensure further decoupling from the underlying storage facility. DAOs interact with services via models and with the database via FlexibleSearch and SQL statements.

Models

Models are a new way to represent Hybris items. Each model contains all item attributes from all extensions thus unifying access to an item's data. Models are generated from the type system of SAP Hybris Commerce. Furthermore they are more or less simple POJOs (Plain Old Java Objects) that can be used without any storage facility. Thus, it's pretty easy to mock them up, for example for testing and debugging. Models are used by DAOs, services, strategies, converters, and facades.

Hybris - Data models

Hybris data model

Hybris Data Models are defined in the <extension>-items.xml file of each extension.

Data model items(entities) are defined with itemtype elements.

Each item type is consist of a Java class and database Table.

items.xml has six different tags and should be followed by same order

automictypes

collections

enumtypes

maptypes

relations

itemtypes

Atomic types: The item types which are primitive data types.

For example, integer, float, double, boolean, Strings etc. They are defined in items.xml as follows.

Collection type: They are analogue of generic types in Java. A collection is a group of similiar type item types. Like a group of language used for a particular application could be stored as LanguageList.

Enum types: The group of fixed constants are defined as enums, like any other language.

</enumtype>

Itemtypes: we need to define a new item type to specifies a specific ComposedType.

<itemtype code="OFFLineProduct" extends="Product"

autocreate="true" generate="true"

jaloclass="org.hm.core.jalo.OFFLineProduct">

<description>OFF Line product extension that contains additional attributes for off line.</description>

<description> the products store name </description>

</attribute>

<description> the time stamp of the product in </description>

</attribute>

<description> the time stamp of the product out </description>

</attribute>

</attributes>

</itemtype>

Here we defined a new item type extending parent item or Generic item.

GenericItem extends LocalizableItem extends ExtensibleItem extends Item

The jalo class, is the module class which creates the item. This class is auto generated. when you run ant build

Each of the characteristics of an item type is defined as attribute of item type. The attribute itself could be of any type.

autocreate - If 'true', the item will be created during initialization. Default is 'true'.

generate - If true, it generates constants for enum and source code for item, it has no effect in automictypes,collections, maptype and relations.

attributes - Defines the list of item attributes.

read – If false, we cannot read this attribute, Defines if this attribute is readable or not.

write – If false, we cannot write this attribute, Defines if this attribute is writable or not.

optional– if false, it is mandatory to initialize this attribute. Since it is not optional.

unique– if true, the attribute must hold a unique value. Similar to unique constraints in DBMS.

search – if true, the attribute is searchable through queries

persistence -

Defines how the values of the attribute will be stored. Possible values: 'property' (persistent), 'dynamic' (not persisted).

defaultvalue -Configures a default value for this attribute used if no value is provided.

maptype: Like the java collection framework, a type, which defines map objects.

<maptype code="localized:java.lang.String"

argumenttype="Language"

returntype="java.lang.String"

autocreate="true"

generate="false"/>

relationtype:

A RelationType defines a n-m or 1-n relation between types.

<relation code="OrderDiscountRelation" autocreate="true" generate="false" localized="false"

deployment="de.hybris.platform.persistence.link.OrderDiscountRelation">

</sourceElement>

</targetElement>

</relation>
