Table of Contents Introduction Understanding Dependency Injection Best Practices for Effective Dependency Injection Final Thoughts Additional Resources Dependency Injection is the core of the Spring Framework. Introduction In the early days of Java, there were lots of heavier enterprise Java technologies for enterprise applications that provided enterprise solutions to programmers. However, it was not easy to maintain the applications because it was tightly coupled with the framework. The Spring Framework provided a very simple, leaner, and lighter programming model compared with other existing Java technologies and it is one of the most widely used frameworks for building robust and scalable Java applications. Spring makes dependency injection possible by using features such as Inversion of Control (IoC) , and aspect-oriented programming (AOP) . Spring allows developers to build applications with simple, framework-independent classes that are easy to test and maintain by using many av
