Chapter 2: Understanding Dependency Injection
In this chapter, we will learn what Dependency Injection (DI) is and how we can use it with the Spring Boot framework. The Spring Boot framework provides DI; therefore, it is good to understand the basics. DI reduces component dependencies and makes your code easier to test and maintain.
In this chapter, we will look into the following:
- Introducing DI
- Using DI with Spring Boot
