What Is Spring Framework?
Spring is a powerful, lightweight application development framework for Java Enterprise Edition (JEE).In the Java Course Framework of frameworks because it supports various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. The broader framework can be defined as a structure with which you can solve many technical problems. You can say that the Spring Framework is a comprehensive tool for supporting applications with Java programming language.
Roderick B. Johnson, an Australian computer specialist, officially released the Spring Framework in 2004.Since its origin Spring Framework has released many versions4.3.8 is the current Spring Framework version.
Features Of The Spring Framework
Lightweight: spring frame is lightweight in terms of size and transparency.
Reversing the control unit (IOC): in the spring frame, the loose coupling is achieved by reversing the control unit. The objects specify their own dependencies instead of creating or searching for dependent objects.
Aspect Oriented Programming (AOP): by separating application business logic from system services, Spring Framework supports Aspect Oriented Programming and enables coherent development.
Container: Spring Framework creates and manages the lifecycle and configuration of application objects.
MVC Framework: Spring Framework an MVC web application framework. This framework is configurable via interfaces and provides space for multiple view technologies.
Transaction management: Spring framework provides a generic abstraction layer for transaction management. It is not bound to J2EE environments and can be used in container-free environments.
JDBC Exception Handling: the Spring Framework JDBC abstraction layer provides an exception hierarchy that simplifies the error handling strategy.
Since its creation to this day, spring has spread its popularity across different domains. Spring Framework is now the basis for various other spring projects that have emerged over the last two to three years in the offerings. Look at the picture below to find out about various projects in the spring.
Spring Tutorial: Benefits Of Using Spring Framework
Works on POJOs (Plain Old Java object), this makes your application easily.
Provides predefined templates for JDBC, Hibernate, JPA, etc., reducing your effort to write too much code.
Due to the dependency injection function, your code is loosely coupled.
With Spring Framework, the development of Java Enterprise Edition (JEE) applications became faster.
It also provides strong abstraction of Java Enterprise Edition (JEE) specifications.
It provides declarative support for transactions, validation, caching, and formatting.
Spring Tutorial: Spring Framework Architecture
As you can see in the diagram below, Spring Framework architecture is a layered architecture consisting of different modules. All the modules have their own functionalities, which are used to create an application. There are around 20 modules that generate in-Core containers, data access/ Integration, Web, AOP (Aspect Oriented Programming), Instrumentation and Test. Here, developers are free to choose the required module. The modular architecture allows integration with other frameworks without much effort.

Let’s now explore these modules in detail. I start with the core container on which the remaining modules are built, then I talk about data access, followed by Web and AOP. Finally, I will discuss some of the different modules.
Spring Tutorial: Modules Of Spring Framework
This container has the following four modules :
1. Spring core: This module is the core of the spring framework. It provides implementation for functions such as IoC (Inversion of control) and Dependency Injection with singleton design pattern.
2. What do you mean? Spring Bean: this module provides the implementation of the factory design pattern by BeanFactory.
3. Spring Context: this module is based on the fixed base of the Core and Beans modules and is a medium for accessing any defined and configured object.
4. Spring Expression Languages (SpEL): this module is an extension of the expression language supported by Java server pages. It provides a powerful expression language for querying and manipulating an object graph at runtime.
