SpringMVC : Throws 415 Unsupported Media Type while attempting POST request call for redirection

Question

Browser response like below:

The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.

Instead of redirecting to the home page ( home.jsp )

welcome.jsp file:

<form method ="POST" action = "<c:url value='/login'/>" >

       <input id="name" name="name" type="text">
       <input id="password" name="password" type="password">
       <input type="submit" id="loginNew" value="LoginNew"> 
  </form>

Controller class:

@RequestMapping( value="/login" , method = RequestMethod.POST )
    public ModelAndView authenticate ( @RequestBody User userObj ) throws Exception {
       ModelAndView modelAndView = new ModelAndView ();
        try {
            user = userService.authenticateUser ( userObj );
        } catch ( Exception e ) {
            e.printStackTrace();
         }
        modelAndView.setViewName("/home");
        return modelAndView;
    }

Answer 1

By adding @ModelAttribute instead of @RequestBody in the method param solved the issue and then redirected to the home.jsp page as expected.

@RequestMapping( value="/login" , method = RequestMethod.POST )
        public ModelAndView authenticate ( @ModelAttribute User userObj ) throws Exception {
           ModelAndView modelAndView = new ModelAndView ();
            try {
                user = userService.authenticateUser ( userObj );
            } catch ( Exception e ) {
                e.printStackTrace();
             }
            modelAndView.setViewName("/home");
            return modelAndView;
        }
