Getting a submitted form value using a controller method argument
In this recipe, you will learn how to get the submitted form data using controller method arguments. This is convenient for simple forms that are not related to a domain object.
How to do it…

@RequestMapping("processForm")
public void processForm(@RequestParam("name") String userName) {

@RequestParam can also retrieve URL parameters, for example, http://localhost:8080/springwebapp/processForm?name=Merlin.

public void processForm(HttpServletRequest request) {
String name = request.getParameter("name");
