Behind the scenes I can say that gets all the best practices of the Spring Framework and uses some default to configure everything in your behalf. Even though we are talking about Spring Boot, it is important to understand what the Spring Framework is and why it is so important for Spring Boot. The Spring Framework implements several design patterns, such as Dependency of Injection and Inversion of Control, Factories, Abstract Factories, Strategies, Singletons, Templates, MVC, and many more. One of the main features of the Spring Framework is that it allows you to work with plain old Java objects (POJOs), making your apps easy to extend without any dependency; in other words, the Spring Framework is not invasive.
