In this example, we'll learn about the Strategy pattern in Spring. We'll cover different ways to inject strategies, starting from a simple list-based approach to a more efficient map-based method. To illustrate the concept, we'll use the three Unforgivable curses from the Harry Potter series — Avada Kedavra, Crucio, and Imperio.
What Is the Strategy Pattern?
The Strategy Pattern is a design principle that allows you to switch between different algorithms or behaviors at runtime. It helps make your code flexible and adaptable by allowing you to plug in different strategies without changing the core logic of your application.
