What is Spring framework in Java ?

 Spring framework

Spring Framework is a powerful lightweight application development framework used for Enterprise Java (JEE).

The core features of the Spring Framework can be used in developing any Java application. It is described as a complete modular framework. This framework can be used for all layer implementations of a real-time application. It can also be used for the development of a particular layer of a real-time application unlike the other frameworks, but with Spring we can develop all layers.

Spring and all the modules including Spring MVC, Spring Core, Spring Security, Spring ORM, etc are used in enterprise applications.

Now, let’s see where is this Spring framework used.

• It targets to make J2EE development easier to use
• Spring supports both XML and annotation based configuration
• It provides backward compatibility and testability of the code

Now, talking about the major companies that use Spring framework for application development, we have,

• Netflix using Spring boot
• Yatra uses Spring MVC
