So far, we have learned why modularity is so important in writing cleaner and maintainable code. In Chapter 1, Why Dependency Injection?, we learned about the Dependency Inversion Principle (DIP), IoC (a design methodology to implement DIP), and various design patterns to implement IoC. Dependency Injection (DI) is one of the design patterns to achieve IoC.
In the Chapter 2, Dependency Injection in Java 9, we learned how modular framework and DI are facilitated in Java 9. In this chapter, we will continue our journey to learn DI in Spring—one of the most popular and widely used frameworks to implement enterprise applications.
In this chapter, we will explore the following topics:
- A brief introduction to Spring ...
