Spring

Software Information
The Spring Framework (Spring) is an open-source application framework that provides infrastructure support for developing Java applications. One of the most popular Java Enterprise Edition (Java EE) frameworks, Spring helps developers create high performing applications using plain old Java objects (POJOs).

The Spring Framework (Spring) is an open-source application framework that provides infrastructure support for developing Java applications. One of the most popular Java Enterprise Edition (Java EE) frameworks, Spring helps developers create high performing applications using plain old Java objects (POJOs).  

A framework is a large body of predefined code to which developers can add code to solve a problem in a specific domain. There are many popular Java frameworks including Java Server Faces (JSF), Maven, Hibernate, Struts, and Spring.

Why Spring ?

Java programs are complex and feature many heavyweight components. Heavyweight means the components are dependent on the underlying operating system (OS) for their appearance and properties.

Spring is considered to be a secure, low-cost and flexible framework. Spring improves coding efficiency and reduces overall application development time because it is lightweight -- efficient at utilizing system resources -- and has a lot of support.

Spring removes tedious configuration work so that developers can focus on writing business logic. Spring handles the infrastructure so developers can focus on the application.  

Without a Spring Framework, application code tends to be tightly coupled (interdependent), which is not considered good coding practice. Loose coupling is ideal because loosely coupled components are independent, meaning changes in one will not affect the operation of others.

Spring’s core logic is dependency injection. Dependency injection is a programming pattern that allows developers to build more decoupled architectures. Dependency injection means that Spring understands the different Java annotations that a developer puts on top of classes. Spring knows that the developer wants to create an instance of a class and that Spring should manage it. Spring also understands the dependency and makes sure that all instances created have properly populated dependencies.
