A class which responds to a particular type of network request - most commonly an HTTP request. Basically servlets are usually used to implement web applications - but there are also various frameworks which operate on top of servlets (e.g. Struts) to give a higher-level abstraction.


Spring helps development teams everywhere build simple, portable, fast and flexible JVM-based systems and applications. Spring's main aim is to make J2EE easier to use and promote good programming practice. It does this by enabling a POJO-based programming model that is applicable in a wide range of environments.

Spring Boot

Lightweight framework that takes most of the work out of configuring Spring-based applications. The goal of Spring Boot is to provide a set of tools for quickly building Spring applications that are easy to configure.

Spring Integration

Lightweight messaging tool within Spring-based applications. Supports integration with external systems via declarative adapters, designed to take multiple systems and abstract away the details of converting messages from one format to another.


Spring MVC

The Spring Web MVC framework provides Model-View-Controller (MVC) architecture and ready components that can be used to develop flexible and loosely coupled web applications. The MVC pattern results in separating the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements.


Free MVC framework for creating elegant, modern Java web applications. It favors convention over configuration, is extensible using a plugin architecture, and ships with plugins to support REST, AJAX and JSON.
