Spring DI Tutorial

What is Spring Framework?

Spring framework is an open source Java platform that provides comprehensive infrastructure support for developing robust Java applications very easily and very rapidly. Spring framework was initially written by Rod Johnson and was first released under the Apache 2.0 license in June 2003.

Why is Spring Dependency Injection, DI?

The technology that Spring is most identified with is the Dependency Injection (DI) flavor of Inversion of Control. The Inversion of Control (IoC) is a general concept, and it can be expressed in many different ways. Dependency Injection is merely one concrete example of Inversion of Control.

When writing a complex Java application, application classes should be as independent as possible of other Java classes to increase the possibility to reuse these classes and to test them independently of other classes while unit testing. Dependency Injection helps in gluing these classes together and at the same time keeping them independent.

In this tutorial, we'll cover all the ways of Dependency Injection in Spring framework which helps in solving the common problems developers/users face in spring framework based applications.

This Spring Depependency Injection tutorial is based on the latest Spring 7.0.0-M9 version.

Who Should Learn Spring DI?

This tutorial is tailored for readers who aim to understand and utilize Spring framework for development using Java programming language. In this tutorial, we'll cover all the ways of using Spring which helps in solving the common problems developers/users face during java based development.

Prerequisites to Learn Spring DI?

To maximize the benefits of this tutorial, readers should have a basic understanding of Java programming. Knowledge of I/O Operations, File handling will enhance comprehension. A basic understanding of Eclipse IDE is also required because all the examples have been compiled using Eclipse IDE.
