Struts中怎么获取request和response对象

1. ActionContext ctx = ActionContext.getContext();           
2.           
3.   HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);           
4.           
5.   HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE); 

 

或者使用：

 

 ActionContext ctx = ActionContext.getContext();
  ctx.getApplication().put("app", "application value");   //Application对象
  ctx.getSession().put("session","session value");          //session对象
  ctx.put("req","request");                                 //request对象
  HttpServletRequest request = ServletActi onContext.getRequest();                 //request对象
  HttpServletResponse response = ServletActionContext.getResponse();            //response对象
  System.out.println(request.getRealPath("/img"));
