SPRING MVC IN JAVA

Spring MVC

• WHAT IS SPRING 
• ADVANTAGES OF SPRING MVC FRAMEWORK

Based on Java, almost all web programs are created with the Spring MVC framework. It 

adheres to the Model-View-Controller (MVC) paradigm. This design pattern defines the three 

components of an application: the data model, presentation data, and control data.

Sending requests to handlers is the responsibility of a Dispatcher Servlet, which is an essential 

component of this design. Although Spring Boot Microservices is gaining traction in the 

industry, Spring MVC is still widely used in many projects. As a result, you must become 

familiar with Spring MVC's most recent version. That's why we will cover the spring MVC 

framework's components separately and methodically.

Spring Model-View-Controller

Model - The model has the application data. A single item or a group of linked items can 

make up a dataset.

Controller - A controller houses the business logic for the application. In this instance, a class 

is designated as a controller using the @Controller annotation.

View - A view represents the provided data in a predetermined format. The process of creating 

the view page often includes JSP+JSTL. However, a greater variety of view technologies, 

such as Free Marker, Thyme Leaf, and Apache Velocity, are compatible with Spring.

Front Controller - The "Dispatcher Servlet" class is the front controller in Spring Web MVC. 

Its responsibility is to oversee a Spring MVC application's execution.

Advantages of Spring MVC Framework

We'll go over a few advantages of the Spring MVC Framework below: In Spring MVC, each 
of the following roles is described by a distinct object: Model Object, Controller, Command 
Object, View Resolver, Dispatcher Servlet, Validator," and "Every Other Role.
Lightweight - It develops and deploys your application using a lightweight servlet.
Strong configuration - provides framework and application classes with strong configuration 
and easy access to a variety of contexts, such as web controls for validators and business 
objects. The development process is accelerated using Spring MVC, which allows for quick 
and parallel development.
Reusable business code - Allows you to use existing business objects instead of creating new 
objects.
Easy to test - In Spring, we usually create JavaBeans classes that allow you to enter a test. 
data with assignment methods.
Flexible mapping - It provides special annotations that easily recheck the page.
