What is Spring Framework?

In our comprehensive guide to integrating Maven with Spring Framework, we will begin by providing an overview of the Spring Framework. Spring is a popular Java framework that provides developers with a powerful set of tools for building enterprise-level applications. It was originally created to simplify Java development and promote good programming practices.

One of the primary features of Spring Framework is dependency injection, which allows for loose coupling between objects in the application. This means that objects are not tightly bound to each other, which makes the application more flexible and easier to maintain over time.

In addition to dependency injection, Spring Framework also utilizes inversion of control, which is a design concept that promotes the idea of letting a framework manage the flow of control in the application. This provides developers with a high degree of flexibility and allows for greater control over complex application architectures.
