Java is a widely-used, easy-to-use, and portable programming language. It is used to write complex programs in a simple way. Every programming language has some platforms or tools called frameworks to develop software applications. A software framework can be defined as a platform that helps a programmer build software applications. Frameworks have a set of programs in which coders can add or modify codes as per application needs to develop their desired applications. There are some frameworks used in Java which include the spring framework. It is a platform for Java developers to build applications in a less complex and easy-to-execute way.

Spring was initially introduced by an Australian IT specialist Rod Johnson in 2003. It became the most popular Java development framework as it provided developers with an easy approach to develop software applications. Spring framework attracts Java developers because it is lightweight (its initial version was approximately 2MB), transparent, and easy to use. Any Java application can be developed by using the Spring framework and applications are easily executed and can be modified as per changing needs. By introducing the Spring framework, Johnson made J2EE development easier for programmers to use. It uses a POJO-based programming model that encourages good programming practices for developers so it is helpful for all Java programmers even for beginners.
