: Defines ports and use cases that coordinate the domain logic.
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?
: Implement inbound ports (e.g., a REST controller). : Defines ports and use cases that coordinate
Hexagonal Architecture, first introduced by Alistair Cockburn, aims to decouple the core logic of an application from external concerns like databases, user interfaces, and third-party services. The "hexagon" represents the application's core, which communicates with the outside world through "ports" (interfaces) and "adapters" (implementations). Core Components
: Interfaces defined by the domain model that specify how the application interacts with external components. What is Hexagonal Architecture
: The heart of the application, containing business logic and rules. It should be independent of any external frameworks or technologies.
: Used by external systems to trigger actions within the application (e.g., an API request). The "hexagon" represents the application's core
: New adapters can be added easily, allowing the application to support multiple interfaces (e.g., CLI, Web, Message Queue). Searching for Further Resources
