spring 获取HttpSession ,HttpServletRequest ,HttpServletResponse

ServletRequestAttributes servletRequestAttributes =(ServletRequestAttributes)RequestContextHolder.currentRequestAttributes();
//获取session
   HttpSession s = servletRequestAttributes.getRequest().getSession();
   //请求
   HttpServletRequest request = servletRequestAttributes.getRequest();
   //应答
   HttpServletResponse response = servletRequestAttributes.getResponse();
  
   System.out.println("spring session= "+s.getCreationTime());
   System.out.println("id:"+s.getId());
   System.out.println("active:"+s.getMaxInactiveInterval());
   System.out.println("真实路径："+request.getRealPath("/"));
   System.out.println("response:"+response);


web.xml 中添加
<listener> 
        <listener-class> 
            org.springframework.web.context.request.RequestContextListener 
        </listener-class> 
</listener>
