One of the most popular Java frameworks for developing web applications is Spring. Almost every web application integrates with Spring Framework because it doesn’t require web server activation. With Spring MVC, this support is built-in. You are not bound to any container life cycle that you need to manipulate. In this Spring MVC Tutorial, I will tell you how to develop a Spring MVC web application using the Spring Tool Suite.

Below topics are covered in this article:

Let’s get started!

What is Spring MVC?

It is a Java framework which is used to build web applications. It follows the Model-View-Controller design pattern. Not just that, it also implements all the basic features of a core Spring Framework like Inversion of Control, Dependency Injection. Spring MVC provides a dignified solution to use MVC in Spring Framework by the help of DispatcherServlet. In this case, DispatcherServlet is a class that receives the incoming request and maps it to the right resource such as Controllers, Models, and Views.

Having understood this, now let’s move further and understand the fundamentals of Spring Web MVC.

Spring Web Model View Controller

It comprises four main components as shown in the below figure:

  • Model – Model contains the core data of the application. Data can either be a single object or a group of objects.
  • Controller – It contains the business logic of an application. You can use @Controller annotation to mark the class as Controller.
  • View – Basically, the View is used to represent the information in a particular format. Here, you can use JSP+JSTL to create a view page.
  • Front Controller – In Spring Web MVC, the DispatcherServlet class works as the front Controller.

Now let’s see how internally Spring integrates with a Model, View and Controller approach.

Workflow of Spring MVC

  • As shown in the figure, all the incoming requests are obstructed by the DispatcherServlet that works as the front Controller.
  • This DispatcherServlet gets an entry of handler mapping from the XML file and forwards the request to the Controller.

  • After that, the Controller returns an object of ModelAndView.

  • Finally, the DispatcherServlet checks the entry of view resolver in the XML file and then invokes the specified view component.

That was all about the workflow of Spring MVC. Now that you know how actually it works, let’s dive deeper into the Spring MVC Tutorial article and know its working with the help of examples.

Spring MVC Framework example

To create a Spring MVC application, you need to follow the below steps:

STEP I: Creation of Maven Project

  • Create a Maven Project and add the Spring Dependencies into the pom.xml file. If you wish to learn how to configure Spring Framework you can refer to this Spring Framework Tutorial.

  • To create a Maven Project for Spring MVC, install Eclipse for JEE developers and follow these steps.

  • Click on File -> New -> Other-> Maven Project -> Next-> Choose maven-archetype-webapp-> Specify GroupID -> Artifact ID -> Package name and then click on finish.

  • The directory structure of your project should look like as shown below:Directory Structure of Spring MVC - Spring MVC Tutorial - Edureka

  • Once you create a Maven Project, the next thing that you have to do is to add maven dependencies in the pom.xml file.

  • Your pom.xml file should consist of the below-mentioned dependencies for Spring MVC.

<project xmlns="" xmlns:xsi="" xsi:schemaLocation="">
<name>SpringMVC Maven Webapp</name>
<!-- -->
<!-- -->
<!-- -->
  • After configuring your pom.xml file, all the required jar files will be imported. You can also copy and paste the required jar files dependency code from the maven repository

After this, the next step is to create a Controller class.

Step II: Create the controller class

In order to create a Controller class, I am using two annotations @Controller and @RequestMapping.

  • The @Controller annotation marks this class as Controller.

  • The @RequestMapping annotation is used to map the class with the specified URL name.

Now let’s see how to do that with the help of the below code:

package com.edureka;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
public class Addition {
public void add(){
int i = Integer.parseInt(req.getParameter("num1"));
int j = Integer.parseInt(req.getParameter("num2");
int k= i+j;
System.out.println("Result is" + k) //returns the result from jsp file

Step III:  Configure the web.xml file and provide entry for Controller class

In this XML file, I am specifying the Servlet class which is DispatcherServlet that acts as the front Controller in Spring Web MVC. All the incoming requests for the HTML file will be forwarded to the DispatcherServlet. Let’s now write the web.xml file. This file will take the mappings and the URL pattern for executing the program.


<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "" >
<display-name>Archetype Created Web Application</display-name>

After this, the next step is to define the bean class file.

Step IV: Define bean in an XML file

This file is necessary to specify the View components. In this, the context:component-scan element defines the base-package where DispatcherServlet will search the Controller class. This file should be present inside the WEB-INF Directory.


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="" xmlns:ctx="" xmlns:xsi="" xmlns:mvc="" xsi:schemaLocation=" ">
<ctx:component-scan base-package="com.edureka">

Now the final step is to write the request in the index.jsp file.

Step V. Create the JSP page

This is the simple JSP page, in which I will perform addition of 2 numbers.


<form action ="add">
Enter 1st number: <input type="text" name="num1">
Enter 2nd number: <input type="text" name="num2">
<input type ="submit">


After all this, you can run the program by starting the server. You will get the desired output. Take a look at the below snap-shot to refer the output:

Once you hit the submit button, the result will be displayed on the screen. Basically, that’s how it works.

That was all about how to create a Spring MVC Application. Having understood this, let’s move further in Spring MVC Tutorial, and know what are the advantages of using Spring MVC.

Advantages of Spring MVC

  1. Lightweight: As Spring is a lightweight framework, there will not be any performance issues in Spring-based web application.

  2. High productive: Spring MVC can boost your development process and hence is highly productive.

  3. Secure: Most of the online banking web applications are developed using Spring MVC because it is highly secure. For enterprise-grade security implementation, Spring security is a great API.

  4. MVC Supported: As it is based on MVC, it is a great way to develop modular web applications.

  5. Role Separation: It comprises of a separate class for specific roles like Model, Command, Validator, etc.

These were some of the advantages of using Spring MVC Framework.

This brings us to the end of the article on Spring MVC Tutorial. I tried my best to keep the concepts short and clear.  I hope you were able to understand what is Spring MVC Framework and how to create a web application using Spring MVC.
