: Used by external systems to trigger actions within the application (e.g., an API request).
: Defines ports and use cases that coordinate the domain logic. : Used by external systems to trigger actions
: Implement inbound ports (e.g., a REST controller). Hexagonal Architecture (also known as Ports and Adapters)
Hexagonal Architecture (also known as Ports and Adapters) is a powerful design pattern for creating maintainable and decoupled software systems. If you're looking for a guide on how to implement this pattern using Java, this article provides a comprehensive overview. What is Hexagonal Architecture? Java's strong typing and interface-driven approach make it
Java's strong typing and interface-driven approach make it an ideal language for implementing Hexagonal Architecture. Here's a typical project structure:
: Implementations of the ports that bridge the gap between the domain model and external systems.
com.example.myapp ├── application │ ├── port │ │ ├── in │ │ └── out │ └── service ├── domain │ ├── model │ └── service └── adapter ├── in │ └── web └── out └── persistence Use code with caution. : Contains pure Java objects and business logic.
