Hello Friends, we need the session object to maintain the session in the web applications. we have to get the session object in Spring MVC by the following method:-

1:- Put the Session object with the method parameter. Session Object is declared as method parameter inside the Controller's method.

@RequestMapping(value="/handleRequest",type=RequestMethod.POST)
 public ModelAndView handleRequest(HttpServletRequest request,HttServletResponse response ,HttpSession session)
{

session.setAttribute("message" , "It is simple to get access to HttpSession "); //to set the session attribute
 return new ModelAndView("success");
 }

2:- Get the Session Object with the help of HttpServletRequest object

@RequestMapping(value="/handleRequest",type=RequestMethod.POST)
     public ModelAndView handleRequest(HttpServletRequest request,HttServletResponse response )
    {
    HttpSession session=request.getSession();
    session.setAttribute("message" , "It is simple to get access to HttpSession "); //to set the session attribute
     return new ModelAndView("success");
     }
