Spring MVC form handling tutorial


Spring mvc framework provides the facility to build flexible and loosely coupled web applications. MVC stands for Model-View-Controller design pattern which separates the business logic, presentation logic and navigation logic. Let us discuss spring mvc form handling example in eclipse.

Example Explanation:

Use http://localhost:8080/SpringMVCExample5/student url to start the application. A request for respective resource will generate. Request will be handled by DispatcherServlet. It delegates the request to the FormHandlingController controller. The LoginController controller resolve the request with help of RequestMapping annotation, executes the specific functionality and returns the ModelAndView object to the DispatcherServlet. The DispatcherServlet then take the help of InternalResourceViewResolver to get the actual view name. In our example it will return the “/WEB-INF/jsp/student.jsp. The DispatcherServlet then insert the model data into view and render response. Same request response cycle will execute when we click on submit button after entering the student details.

Example:

student.jsp
