Spring 获得httpServletRequest

首先，需要在web.xml中添加一个spring的监听

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

然后 这样就可以获得

ServletRequestAttributes request =(ServletRequestAttributes) RequestContextHolder.getRequestAttributes();  
               
        HttpSession session=request.getRequest().getSession();
