A complete, open-source example of a Domain-Driven Design enterprise application built on the Java Spring stack. It demonstrates DDD tactical patterns (aggregates, domain events, value objects) alongside hexagonal architecture and CQRS/CRUD segregation in a realistic codebase.

Use cases

• learn domain-driven design with a full example
• see how to structure a hexagonal architecture Spring application
• understand aggregates and domain events in practice
• study CQRS vs CRUD segregation in an enterprise app
• find a reference implementation of DDD in Java
• learn event storming outcomes mapped to code

When to choose

• you want a complete, realistic DDD codebase to study rather than toy snippets
• your team builds with Java/Spring and wants idiomatic DDD patterns
• you need examples of hexagonal architecture with ports and adapters
• you want to see how CRUD and complex domain logic coexist in one app

When to avoid

• you need a production-ready framework or library to depend on - this is a reference example
• you work outside the JVM/Spring ecosystem
• you need actively maintained code with recent releases (last release 2022)
