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.
