The Java Spring Framework is a platform that provides comprehensive infrastructure support for developing Java applications. Spring handles the infrastructure so you can focus on your application. 

Java spring framework enables you to build applications from "plain old Java objects" (POJOs) and apply enterprise services non-invasively to POJOs. This capability applies to the Java SE programming model and full and partial Java EE.

One of the chief advantages of the Spring framework is its layered architecture, which allows you to be selective about which of its components you use while also providing a cohesive framework for J2EE application development.

 The Java spring framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic without unnecessary ties to specific deployment environments.

Any Java application can use the framework's core features, but there are extensions for building web applications on top of the Java EE platform. Although the Spring Framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, a replacement for, or even addition to the Enterprise JavaBean (EJB) model.

The main benefit of using Spring Framework is simplifying the application development process by providing ready-to-use components right out of the box. It also makes your code easier to test and maintain because it follows a set of standards.

Spring Framework has a number of modules that provide solutions to many commonly faced problems when building enterprise applications.

Spring MVC simplifies building web applications by providing a clean separation between domain model code and web forms.
