The goal of this project is to showcase a possible implementation of a hexagonal architecture (aka "Ports & Adapters") using Kotlin and Spring Boot. The project is divided into three modules:
Contains all business logic - UserManager - the interfaces for the outside world (the ports) and the models.
Usually, this project would contain most of our unit tests
Contains all implementation details (adapters) for the ports described in the hex-domain project
The API itself. It uses Spring's dependency injection capabilities to wire all stuff from hex-api
and hex-domain. Here we could add integration tests, for example.
