SAP Commerce Development

Overview

SAP Commerce Cloud (formerly Hybris) is an enterprise e-commerce platform built on Java and Spring. This skill provides guidance for extension development, type system modeling, service layer implementation, data management, API customization, accelerator patterns, Composable Storefront (Spartacus/Angular) integration, CCv2 cloud deployment, SAP BTP/Kyma integration, SmartEdit customization, and testing patterns for both Cloud (CCv2) and On-Premise deployments.

Modern Storefront Note: The JSP-based Accelerator storefront (Spring Web Flow, JSP/JSTL) is the legacy approach. The modern recommended storefront is Composable Storefront (formerly Spartacus) — an Angular/TypeScript Single Page Application that communicates with the backend exclusively via OCC REST APIs. New projects should use Composable Storefront. See composable-storefront.md.

Core Architecture

Type System

Data modeling via items.xml defines item types, attributes, relations, and enumerations. Types are compiled into Java classes during build. See type-system.md for syntax and patterns.

Extensions

Modular architecture where functionality lives in extensions. Each extension has extensioninfo.xml for metadata, items.xml for types, and *-spring.xml for beans. See extension-development.md.

Service Layer

Four-layer architecture: Facade (API for controllers) → Service (business logic) → DAO (data access) → Model (generated from types). See service-layer-architecture.md.
