Why is Java Spring so popular?

Java Spring

Java Spring is a powerful, lightweight framework that is used to develop web and enterprise applications. In wider terms, you can say that the Spring framework is a well-defined instrument that uses Java as a programming language to support multiple web applications.

Prior to the lunch of Spring, the applications were created using JEE standards. We can deploy an application with these standards on any JEE application server. But it had a number of issues, including: the component’s look-up issue, as implementation advanced, the code became very complex, system performance was impacted by the application’s complexity. With the implementation of the Spring Framework, these issues were mitigated. Spring also removed a lot of boilerplate code and as a result, your code didn’t have to be tangled with it.

Spring has been open source since its launch. The project is presently being maintained by Pivotal Software. The community, however, plays a major part in its growth. 

Most Important Spring Framework features

Aspect-oriented programming (AOP) 

This is an important component of the Spring Framework. Aspect-oriented programming is used to separate cross-cutting concerns (such as logging, security, etc.) from the application’s business logic.

Dependency Injection

This Spring Framework feature enables you to create applications that are loosely coupled. Therefore, it becomes simpler to test unit these loosely coupled applications. This also makes it possible for the developer to exchange some of the modules as needed.


In terms of size and functionality, the Spring Framework is very lightweight. This is because of its implementation of POJO, which Spring does not force to inherit any class or to implement any interfaces.

Transaction Management

Used to unify multiple transaction management APIs, and it is used to coordinate Java object transactions. It is also not connected to the J2EE setting and is used in container-free environments.


The Spring framework designs and manages the application objects lifecycle and configurations. This makes it easier to test code.

Integration With Other Frameworks

A good thing about this framework is not trying to fix the issues that have already been solved. It’s just trying to incorporate them into its structure, which provides a solution to bigger issues.


Today Spring is the de-facto standard for java web application development, and as previously mentioned it has a thriving community that supports its development, in addition, the popularity of Java as a programming language makes it so that I don’t see it going anywhere.
