There are two types of ports: input and output. We implement the first ones in the domain layer, while the infrastructure module will contain the implementation of the second ones. 10 | 11 | ## Example 12 | Let’s consider a simple Product REST Service to understand this architecture. Resources of the product service are: 13 | 14 | Create a Product 15 | Get the Product by Id 16 | 17 | We start creating the three layers: application, infrastructure, and domain. 18 | 19 | ## Application 20 | The application layer will contain the ports, which are interfaces that allow inbound or outbound flow. 21 | 22 | We created use cases inside the input package, defining what the user would like to do in the application. 23 | In our example, create new products and get them by Id. 24 | 25 | On the other hand, we use the output package to connect to some external components. 26 | In our example, ProductOutputPort will get data from the database. 27 | 28 | ## Infrastructure 29 | The infrastructure layer represents the outer part of the hexagonal architecture through adapters. 30 | 31 | Adapters interact with the core application only by using the inbound and outbound ports. 32 | 33 | We divide the infrastructure.adapters package into three new ones: 34 | 35 | 1. config: it contains the beans of the application 36 | 2. input: it drives the application by invoking the corresponding use case (input port) 37 | 3. output: it provides an implementation of the output ports (databases or messaging queues) 38 | 39 | ## Domain 40 | The domain layer is the center of the system. It handles the business logic and represents the application core. 41 | 42 | The domain layer is wholly decoupled from application and infrastructure layers, so changes in the other layers have no impact on the Product domain object unless there is a change in the business requirements. 43 | 44 | The ProductService is a crucial component inside the domain, as it implements the input ports and uses the output interfaces implemented by the output adapters to return the result to the input adapters 45 | -------------------------------------------------------------------------------- /mvnw: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | # ---------------------------------------------------------------------------- 3 | # Licensed to the Apache Software Foundation (ASF) under one 4 | # or more contributor license agreements.
