Android网络编程之一个Android下菜单系统模块的实现(服务器端—添单功能)

public class OrderDetailServlet extends HttpServlet {

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html");
// 获取输出打印流
PrintWriter pw = new PrintWriter(resp.getOutputStream());

// 读取请求中的order数据
String orderId = req.getParameter("orderId");
String menuId = req.getParameter("menuId");
String dishNum = req.getParameter("dishNum");
String remark = req.getParameter("remark");

// 将数据添加到一个OrderDetail表对象实例
OrderDetail detail = new OrderDetail();
detail.setOrderId(Integer.parseInt(orderId));
detail.setMenuId(Integer.parseInt(menuId));
detail.setNum(Integer.parseInt(dishNum));
detail.setRemark(remark);

// 定单数据存入MySQL端，更新对应桌号是否有人的状态,并获得返回的订单号传回客户端
OrderDao orderDao = new OrderDaoImpl();
orderDao.saveOrderDetail(detail);
pw.print("Dishes added successfully");
pw.flush();
pw.close();
}

@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
doGet(req, resp);
}
