4、ment to change the way programmers approach developing Java 2 Platform, Enterprise Edition (J2EE) Web applications. Our focus is how to create J2EE-compliant software without using Enterprise Java Beans (EJB). The one

5、 of the best alternative is the Spring framework, which provides less services but it is much less intrusive than EJB. The driving force behind this shift is the need for greater productivity and reduced complexity in

6、the area of Web application software development and implementation. In this paper, we briefly describe spring underlying architecture and present a case study using Spring web MVC Framework. Index Terma: MVC, Spring,

7、 XML I. INTRODUCTION Web is the very complex issues these days. Since the desire of the companies and organizations are increasing so the complexity and the performance of the web programming matters. Complexity with th

8、e different types of communication devices is increasing. The business is demanding applications using the web and many communication devices. So with the increase load of the data on the internet we have to take care

9、of the architecture issue. Let us discuss how it works fast using spring web mvc framework the rapid application development while maintaining the Model View Architecture of the application. Spring frameworks comes wit

10、h rich set of features, let us discuss these features in brief. 1 Inversion Of Control: Inversion of Control or IoC is one of the techniques used to wire services or components to an application program. The IoC is “

11、A software design pattern and set of associated programming techniques in which the flow of control of a system is inverted in comparison to the traditional interaction mode.” In IoC instead of an application calling t

12、he framework, it is the framework that calls the components specified by the application. The IoC can be explained as “Injection of required resources or dependency at run-time into the dependent resource“ which is als

13、o known as Dependency Injection. The org.springframework.beans.factory.BeanFactory is the actual representation of the Spring IoC container which is responsible for containing and managing the beans. The BeanFactory in

14、terface is the central IoC container interface in Spring. A bean is simply an object that is instantiated and managed by a Spring IoC container. These beans and the dependencies between them are reflected in the config

15、uration metadata used by a container. 2. Constructor Dependency Injection: we can use the java class constructor to load the bean values. A java Class is defined with a constructor of single field. Details.xml file pro

16、vides the value to be passes to the constructor. Now another java loads the xml file using the BeanFactory Method. This uses the xml file to load values in the constructor of the java file. This is used to pass values

17、to the constructor. 3. Setter Dependency Injection: With every bean we defined the getters and setters. We can also use setters method to set the values in the beans. setters method overrides the values loaded from th

19、the dispatcher Servlet is the entry point for the application. As soon the Dispatch Servlet get the request for the services and it will decides the handler. All handlers are mapped with the Servlet. Handler will come

20、in action and will call the respective controller and the pass the request parameters to it. Now controller comes in action, it contains business logic and a ModelAndView is associated with the controller. on executi

21、on it will return the ModelAndView to the Dispatch Servlet. This ModelAndView contains the data and view name. Dispatcher Servlet gets the ModelAndView from the controller. It contains the data and view name. Servlet w
