The following ways to read the data from the form are :
* HttpServletRequest interface : The HttpServletRequest is a java interface present in javax.servlet.http package. Like Servlets, you can use HttpServletRequest in Spring to read the HTML form data provided by the user.
* @RequestParam annotation : The @RequestParam annotation reads the form data and binds it automatically to the parameter present in the provided method.
* @ModelAttribute annotation : The @ModelAttribute annotation binds a method parameter or its return value to a named model attribute.
