Introducing Spring Framework
Introducing Spring Framework Introducing Spring Framework
Chapter 1 Your First Spring Application Most books start with a very long explanation about the technology they are using, the history of it, and often a small example that you can’t run until you reach later chapters. In this book, I am going to take a different approach. I am going to start with some basic examples and I will explain in detail what they do and how to use them so that you get to know Spring quickly. The examples in this chapter will show you how easy it is to integrate the Spring Framework into any existing project or how to start one from scratch and modify it without any effort. Figure 1-1 shows the Spring Framework web site, http://spring.io. In this web site, you can find all of the Spring Extensions, guides, and documentation to help you understand better the Spring ecosystem. Figure 1-1. Spring I/O 3
Chapter 1 ■ Your First Spring Application Pre-Requirements In order to start with the first example you need to have some tools installed. • You need the Java JDK installed and configured. (The JVM must be accessible on the command line, either Windows or Unix). You can install the JDK 1.6 and above. Look for it at this link: www.oracle.com/technetwork/java/javase/downloads/index.html. • Because you are going to use the latest version of Spring Framework, version 4.0.5.RELEASE, you are going to use Gradle to build and run your examples. So far Gradle is one of the best building tools available today that runs using Groovy as a primary language; it is extensible and robust; contains a better library management that can be extended; and is now the preferred way by the Spring core team to build the Spring Framework and its Extensions. If you want to know more about Gradle, take a look at their web site at www.gradle.org (see Figure 1-2). Figure 1-2. Gradle Web Site 4
