The following is Spring-related Java code we need to write for our . Spring Web MVC Concepts : The world of Java has seen many MVC design pattern-based web frameworks crop up in the past few years (several are listed at the very end of this chapter). MVC was originally conceived at XEROX PARC around the 1978–79 time frame and was later implemented in the Small talk-80 class library (also at XEROX PARC). It is a relatively simple concept to grasp and provides for a clean separation of presentation and data, as I'll explain briefly here.  The Spring Web MVC Framework is a robust, flexible, and well-designed framework for rapidly developing web applications using the MVC design pattern.The benefits achieved from using this Spring module are similar to those you get from the rest of the Spring Framework. Let’s review a few of these. I will demonstrate some of these benefits later in this chapter. Easier testing : This is a common theme you will find across all the Spring classes. The fact that most of Spring's classes are designed as JavaBeans enables you to inject test data using the setter methods of these classes. Spring also provides mock classes to simulate Java HTTP objects (HttpServletRequest, for example), which makes unit testing of the web layer much simpler. Bind directly to business objects—Spring MVC does not require your business (model) classes to extend any special classes; this enables you to reuse your business objects by binding them directly to the HTML forms fields. In fact, your controller classes are the only ones that are required to extend Spring classes (or implement a Spring controller interface).
