To keep the hexagon isolated, you must enforce strict dependency rules:

The ports define the interfaces through which the application interacts with the outside world. For the user authentication feature, we'll define two ports: To keep the hexagon isolated, you must enforce

: Learn to build a "Domain Hexagon" using entities and value objects that are entirely technology-agnostic. Visualizing the Structure A major selling point of

package com.example.order.domain; import java.math.BigDecimal; import java.util.UUID; public class Order private final UUID id; private final BigDecimal totalAmount; private String status; public Order(UUID id, BigDecimal totalAmount) this.id = id; this.totalAmount = totalAmount; this.status = "CREATED"; public void complete() this.status = "COMPLETED"; // Getters public UUID getId() return id; public BigDecimal getTotalAmount() return totalAmount; public String getStatus() return status; Use code with caution. 2. The Ports (The Hexagon Boundaries) Next, define the interfaces. An defines what the application can do: To keep the hexagon isolated

: Ports define how the outside communicates with the inside. Visualizing the Structure

A major selling point of the architecture—and the book—is testing. The book features:

The Hexagonal Architecture pattern consists of the following key components:
