A very simple implementation of Strategy Design Pattern and Factory Design Pattern to a Spring Boot project.

Strategy Design Pattern in Spring Boot

Discover the simplest and most effective way to implement strategy patterns in Spring Boot with the provided implementation.

This project provides clear and concise examples of these powerful design patterns in action, along with detailed explanations that make it easy to understand and apply them to your own Spring Boot projects.

The project primarily uses Spring Boot dependency injection with autowiring to resolve the created strategies, which enabled you to comply with O of SOLID design principles, i.e. Open-Closed Principle.

Which means, to add a new strategy, all you have to do is just have to provide a new implementation of your strategy interface and that's it. Spring will automatically resolve the dependencies and will map it to the provided type.

How to run

The application uses Spring Boot and starts on post 9000 by default. You can simply build and run the project similar to how to run any other spring boot applications.

The application will execute the test() method in the NotificationExecutor, which calls NotificationFactory for each of three supported notification types. It will produce the below output:

Sending email
Sending push notification
Sending SMS

How was it done?

To understand further, you can go through a step-by-step guide that I have created on how it was implemented.
