2）OrderService类

//更新订单public void updateOrder(Orders order){try {orderDao.updateOrder(order);} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

3）OrderServlet类

public void confirmSubmitOrder(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{Map<String,String[]> properties=  request.getParameterMap();Orders order=new Orders();try {BeanUtils.populate(order, properties);} catch (IllegalAccessException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (InvocationTargetException e) {// TODO Auto-generated catch blocke.printStackTrace();}orderService.updateOrder(order);

	}

2.使用易宝支付

1）导入merchantInfo.properties 放在src目录下
