关于servlet监听器和过滤器的例子,大家如果有这方面的需求的话可以

public HttpSession getSession()
{
    Cookie[] cookies = request.getCookies();
    for(int i = 0; i < cookies.length; i++)
    {
        if(cookies[i].getName().equals("JSESSIONID"))
        {
            String sessionId = cookies[i].getValue();
            if(sessions.get(sessionId) == null)
            {
                sessionImpl = new SessionImpl();
                sessionImpl.setId(IDGenerator.radomId());
                sessions.put(SessionImpl.getId(), SessionImpl);
                Cookie c = new Cookie();
                c.setName("JSESSIONID");
                c.setValue(SessionImpl.getId());
                response.addCookie(c);
            }else
            {
                return sessions.get(sessionId);
            }
        }
    }
}
