Struts2的request session

      1.   直接到ActionContext里找出来,Ps： 要把这个快速的获得方式放到方法体内，否则报空指针。。 原因有待考究

   

HttpServletRequest request = ServletActionContext.getRequest();

                       HttpSession session = ServletActionContext.getRequest().getSession(); 

 

        2.  还有另一种，IoC  依赖注入

                private Map<String,Object> request ;
	private Map<String,Object> session ;
	
	public void setSession(Map<String, Object> request) {
		// TODO Auto-generated method stub
			this.request = request;
	}

	public void setRequest(Map<String, Object> request) {
		// TODO Auto-generated method stub
		this.request = request;
	}
