Spring Framework Web Layer Modules Explained

Learn about Spring Framework Web Layer modules including Web, Servlet, WebSocket, and Portlet modules with explanations.

The Spring Framework Web Layer provides modules for building web applications, REST services, and WebSocket-based communication. Understanding these modules is important for Spring developers and Java interview preparation. In this article, we will explore the major modules available in the Spring Web Layer.

Web Module

• This module provides basic web-oriented integration features, such as initialization of the IoC container using Servlet listeners and a web-oriented application context.
• It also provides support for web-related functionalities and remote services.

Servlet Module

• The Servlet module contains the Spring MVC (Model-View-Controller) framework for building web applications.
• It separates business logic, presentation logic, and request handling using the MVC pattern.
• It provides support for Servlet-based web applications, including features such as controllers, view resolvers, and Servlet listeners.

WebSocket Module

• This module provides support for WebSocket-based messaging and real-time communication between clients and servers.
• It enables bidirectional communication over a single TCP connection.

Portlet Module

• This module provides the MVC implementation for applications running in a Portlet environment.
• It is similar to the Servlet module but is designed specifically for portlet-based applications.
