Clean Architecture, Hexagonal Architecture & DDD for Spring Boot
Overview
This skill provides comprehensive guidance for implementing Clean Architecture, Hexagonal Architecture (Ports & Adapters), and Domain-Driven Design tactical patterns in Java 21+ Spring Boot 3.5+ applications. It ensures clear separation of concerns, framework-independent domain logic, and highly testable codebases through proper layering and dependency management.
When to Use
- Architecting new Spring Boot applications with clear separation of concerns
- Refactoring tightly coupled code into testable, layered architectures
- Implementing domain logic independent of frameworks and infrastructure
- Designing ports and adapters for swappable implementations
- Applying Domain-Driven Design tactical patterns (entities, value objects, aggregates)
- Creating testable business logic without Spring context dependencies
