Domain-Driven Design with Java - A Practitioner’s Guide

By: Premanand Chandrasekaran, Karthik Krishnan

Overview of this book

Domain-Driven Design (DDD) makes available a set of techniques and patterns that enable domain experts, architects, and developers to work together to decompose complex business problems into a set of well-factored, collaborating, and loosely coupled subsystems. This practical guide will help you as a developer and architect to put your knowledge to work in order to create elegant software designs that are enjoyable to work with and easy to reason about. You'll begin with an introduction to the concepts of domain-driven design and discover various ways to apply them in real-world scenarios. You'll also appreciate how DDD is extremely relevant when creating cloud native solutions that employ modern techniques such as event-driven microservices and fine-grained architectures. As you advance through the chapters, you'll get acquainted with core DDD’s strategic design concepts such as the ubiquitous language, context maps, bounded contexts, and tactical design elements like aggregates and domain models and events. You'll understand how to apply modern, lightweight modeling techniques such as business value canvas, Wardley mapping, domain storytelling, and event storming, while also learning how to test-drive the system to create solutions that exhibit high degrees of internal quality. By the end of this software design book, you'll be able to architect, design, and implement robust, resilient, and performant distributed software solutions.

Bootstrapping the UI

We will simply be building the UI for the LC application we created in Chapter 5, Implementing Domain Logic. For detailed instructions, refer to the Bootstrapping the application section. In addition, we will need to add the following dependencies to the dependencies section of the Maven pom.xml file in the root directory of the project:

To run UI tests, you will need to add the following dependencies:

To be able to run the application from the command line, you will need to add javafx-maven-plugin to the plugins section of your pom.xml file, per the following:

To run the application from the command line, use the following:

mvn javafx:run

Important Note

If you are using a JDK greater than version 1.8, the JavaFX libraries may not be bundled with the JDK itself. When running the application from your IDE, you will likely need to add the following:

--module-path=<path...
