如何在struts2中响应http请求

Answer 1

ActionContext context=ActionContext.getContext(); --得到Action执行的上下文
Map request=(Map)context.get("request");--得到HttpServletRequest的Map对象
Map session=context.getSession();--得到HttpSession的Map对象
Map application=context.getApplication();--得到ServletContext的Map对象

Map session = ActionContext.getContext().getSession();//获取Session
ServletActionContext.getResponse().addCookies(key,valuue); //写入Cookie

HttpServletResponse response = (HttpServletResponse)ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_RESPONSE);
HttpServletRequest request = (HttpServletRequest)ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_REQUEST);
