解决方案四：
我吧action里改成了这样，那位会的，帮我看看，急用，一万分的感谢//查询条件publicStringexecuteD(){HttpServletRequestrequest=ServletActionContext.getRequest();TopicDAOto=newTopicDAO();System.out.println("paperNo"+paperNo);Topictop=to.queryByPaperNo(paperNo);if(top!=null){//Map<String,Object>session=ActionContext.getContext().getSession();//session.put("top",top);request.getSession().setAttribute("top",top);System.out.println("查询成功");System.out.println(top.getA());return"have";}return"never";}
