webwork中的action如何取HttpServletRequest和HttpServletResponse对象

方法一:

  ActionContext ctx=ActionContext.getContext();  

HttpServletRequest request=(HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);  

HttpServletResponse response=(HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);

方法二:

HttpServletRequest request=ServletActionContext.getRequest();
HttpServletResponse response=ServletActionContext.getResponse();

方法三:

实现ServletRequestAware接口,并实现 

public void setServletRequest(HttpServletRequest request) ;方法
