在struts2的Action中使用request和response的技巧

ActionContext ctx = ActionContext.getContext(); HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST); HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE); //ServletActionContext.APPLICATION; //ServletActionContext.SESSION; //ServletActionContext.PAGE_CONTEXT;
