public String execute() {Watch watch = new Watch();watch.setNum(1);watch.setOnLine("asdfasdf");JSONObject jo = JSONObject.fromObject(watch);String jsonStr = jo.toString();System.out.println(jsonStr);try {// 返回成功标识response.getWriter().println("{success:true}");response.getWriter().println("{watch:"+jsonStr+"}");response.getWriter().flush();} catch (IOException e) {e.printStackTrace();} finally {try {response.getWriter().close();} catch (IOException e) {e.printStackTrace();}}return null;}
