For those looking to get started with domain-driven design in Java, the process is simpler than you might expect. In this tutorial video, we provide a comprehensive guide on how to implement domain-driven design in Java, covering everything from creating domain packages to implementing the necessary classes and methods.
To begin, we start by creating the domain package and adding a user class with various information such as ID, first name, last name, email address, and password. We then assign rules to the user, such as admin or manager status.
Next, we delve into the annotations required for persistence and table naming, as well as utilizing Lombok for code generation. We also cover the creation of user rules as an enum class, with annotations for the table and entity.
Once the domain structure is in place, we move on to the repository interface, where we define the necessary methods for interacting with the database. Following this, we establish the service layer, injecting the repository to handle data manipulation.
Finally, we create the user controller as the entry point for interacting with the system, defining the REST endpoints and injecting the user service.
By the end of this tutorial, you will have all the necessary classes and methods to kickstart your domain-driven design implementation in Java. Whether you need to create, delete, or update users, this guide has you covered.
