The Spring Framework

Are you ready to supercharge your Java applications? Look no further than the Spring Framework!

The Spring framework is an open source software development framework that uses Java Enterprise Edition (Java EE) and the Enterprise JavaBeans model (EJB).

Released in June 2003 by Rod Johnson under the Apache 2.0 license.

It supports other integrated frameworks in the Java ecosystem, like Struts, Hibernate, and Tapestry. Spring comes in many variants that are tailored to particular uses, such as Spring MVC, Spring Boot, or Spring Security.

Spring is known for its dependency injection and Inversion of Control (IoC) systems, which allow you to create large-scale, loosely coupled.

Spring MVC follows the MVC architecture pattern, which separates an application into three interconnected components: ?????? ??????????, ?????? ????????, ?????? ?????? ????????????????????.

??????????:?Responsible for managing the data.

????????:?Responsible for displaying the data to the user.

????????????????????:?Responsible for handling user requests, it acts as the mediator between the model and view components.

?????????????????? ???? ???????????? ?????? ????????????????????????:

Spring MVC has several components that work together to handle HTTP requests and generate responses.

?????????????????????????????????? :

The DispatcherServlet is the central component of Spring MVC. It receives all incoming requests and delegates them to the appropriate handler.

???????????????????????????? :

The HandlerMapping component maps incoming requests to the appropriate handler method in the controller.

?????????????????????:

The Controller component contains the business logic of the application and is responsible for processing the incoming requests and generating the appropriate response.

???????????????????????? :

The ModelAndView component represents the model and view components of the application. It contains the data that will be displayed in the view and the view that will be used to display the data.

Whether you're developing a small-scale application or a large-scale enterprise system, the Spring Framework provides the tools and capabilities to streamline development
