Spring Essentials

Overview of this book

Spring is an open source Java application development framework to build and deploy systems and applications that run on the JVM. It is the industry standard and the most popular framework among Java developers with over two-thirds of developers using it. Spring Essentials makes learning Spring so much quicker and easier with the help of illustrations and practical examples. Starting from the core concepts of features such as inversion of Control Container and BeanFactory, we move on to a detailed look at aspect-oriented programming. We cover the breadth and depth of Spring MVC, the WebSocket technology, Spring Data, and Spring Security with various authentication and authorization mechanisms. Packed with real-world examples, you’ll get an insight into utilizing the power of Spring Expression Language in your applications for higher maintainability. You’ll also develop full-duplex real-time communication channels using WebSocket and integrate Spring with web technologies such as JSF, Struts 2, and Tapestry. At the tail end, you will build a modern SPA using EmberJS at the front end and a Spring MVC-based API at the back end.By the end of the book, you will be able to develop your own dull-fledged applications with Spring.

Your first Spring MVC application


Let's jump to creating a very simple Spring MVC web application. For the purpose of learning, we will develop the web version of Taskify, the task management system we started in Chapter 1, Getting Started with Spring Core. The samples in this chapter use Spring Tool Suite (STS) as the IDE, but you can use your favorite IDE, such as IntelliJ and NetBeans. Almost all Java IDEs support Spring development; most of them have plugins to manage Spring projects and artifacts.

To begin with, follow these steps; then, we will explore the code:

  1. Open STS or Eclipse → create a new project → type a project name → select a template, either Spring MVC Project or Simple Spring Web Maven → specify the top-level package name → finish. Your project structure will be generated.

  2. Make sure your pom.xml file contains Maven dependencies for the spring-context, spring-mvc, servlet-api, jsp-api, and jstl libraries. Note that jsp-api and jstl are required only if you are using JSP as...
