Spring MVC: Beginner's Guide - Second Edition

Overview of this book

Spring MVC helps you build flexible and loosely coupled web applications. The Spring MVC Framework is architected and designed in such a way that every piece of logic and functionality is highly configurable. Also, Spring can integrate effortlessly with other popular web frameworks such as Struts, WebWork, Java Server Faces, and Tapestry. The book progressively teaches you to configure the Spring development environment, architecture, controllers, libraries, and more before moving on to developing a full web application. It begins with an introduction to the Spring development environment and architecture so you're familiar with the know-hows. From here, we move on to controllers, views, validations, Spring Tag libraries, and more. Finally, we integrate it all together to develop a web application. You'll also get to grips with testing applications for reliability.

Model View Controller

So far, we have looked at lots of concepts such as the Dispatcher servlet, request mapping, controllers, and the view resolver, but it would be good to see the overall picture of the Spring MVC request flow so that we can understand each component's responsibilities. But before that, you need a basic understanding of the Model View Controller (MVC) concept. Every enterprise level application's Presentation layer can be logically divided into three major parts:

  • The part that manages the data (Model)

  • The part that creates the user interface and screens (View)

  • The part that handles interactions between the user, the user interface, and the data (Controller)

The following diagram should help you to understand the event flow and command flow within an MVC pattern.

The classic MVC pattern

Whenever a user interacts with the view by clicking on a link or button, or something similar, the view issues an event notification to the controller and the controller issues a command notification...
