hexagonal-architecture-layers-java

What problem does it solve?

This skill addresses the challenge of maintaining clean architecture boundaries in Java applications, helping teams keep domain logic decoupled from frameworks and infrastructure.

Core Features & Use Cases

• Enforces Domain is pure: no framework annotations, no persistence concerns, no I/O in the domain.
• Defines Application layer use cases and ports that orchestrate domain logic and IO through adapters.
• Infrastructure wiring: adapters that connect controllers, repositories, and external services while respecting dependency direction.

Quick Start

To apply hexagonal architecture layering to a Java project, begin by identifying Domain, Application, and Infrastructure boundaries and implement sample Domain model and ports as shown in the guide.
