Right now I am using

HttpSession objHttpSession = re

Answer 1

I usually declare a parameter of type HttpSession in my Spring MVC controller method when I need to access session details.

For example:

@RequestMapping("/myrequest")
public void handleMyRequest(HttpSession session, ...) {
   ...
}

I think it's the simplest way, but don't know if it fits your needs.

You can get the session in Spring MVC like this:

ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
HttpSession session = attr.getRequest().getSession();

The currentRequestAttributes method return the RequestAttributes currently bound to the thread in which there is a current request and from that request you can get the session. This is useful when you need to get hold of the session in non-spring class. Otherwise you can just use:

@RequestMapping(...)
public void myMethod(HttpSession session) {   
}

Spring will inject HttpSession instance into your controller's method.
