Java Web 網絡商城案例演示二十二
查詢訂單
步驟分析：
步驟實現：
1、準備工作：/admin/letf.jsp
d.add('0105','01','訂單管理');
d.add('010501','0105','訂單管理','${pageContext.request.contextPath}/AdminOrderServlet?method=findOrders','','mainFrame');
d.add('010502','0105','未付款的訂單','${pageContext.request.contextPath}/AdminOrderServlet?method=findOrders&state=1','','mainFrame');
d.add('010503','0105','已付款訂單','${pageContext.request.contextPath}/AdminOrderServlet?method=findOrders&state=2','','mainFrame');
d.add('010504','0105','已發貨的訂單','${pageContext.request.contextPath}/AdminOrderServlet?method=findOrders&state=3','','mainFrame');
d.add('010505','0105','已完成的訂單','${pageContext.request.contextPath}/AdminOrderServlet?method=findOrders&state=4','','mainFrame');
2、 AdminOrderServlet–》findOrders方法當中
獲取全部的訂單
public class AdminOrderServlet extends BaseServlet {
OrderService orderService = new OrderServiceImpl();
// findOrders
public String findOrders(HttpServletRequest request, HttpServletResponse response) throws Exception {
String st = request.getParameter("state");
List<Order> list = null;
if (null == st || "".equals(st)) {
// 獲取到全部的訂單
list = orderService.findAllOrders();
}else {
list = orderService.findAllOrders(st);
}
// 將全部的訂單放入到request
request.setAttribute("allOrders", list);
// 轉發到/admin/order/list.jsp
return "/admin/order/list.jsp";
}
}
OrderService
public interface OrderService {
List<Order> findAllOrders() throws Exception;
List<Order> findAllOrders(String st) throws Exception;
}
OrderServiceImpl
public class OrderServiceImpl implements OrderService {
OrderDao orderDao = new OrderDaoImpl();
@Override
public List<Order> findAllOrders() throws Exception {
return orderDao.findAllOrders();
}
@Override
public List<Order> findAllOrders(String st) throws Exception {
// TODO Auto-generated method stub
return orderDao.findAllOrders(st);
}
}
OrderDao
public interface OrderDao {
List<Order> findAllOrders() throws Exception;
List<Order> findAllOrders(String st) throws Exception;
}
OrderDaoImpl
public class OrderDaoImpl implements OrderDao {
@Override
public List<Order> findAllOrders() throws Exception {
String sql = "select * from orders";
QueryRunner qr = new QueryRunner(JDBCUtils.getDataSource());
return qr.query(sql, new BeanListHandler<Order>(Order.class));
}
@Override
public List<Order> findAllOrders(String st) throws Exception {
String sql = "select * from orders where state = ?";
QueryRunner qr = new QueryRunner(JDBCUtils.getDataSource());
return qr.query(sql, new BeanListHandler<Order>(Order.class),st);
}
}
3、在/admin/order/list.jsp下獲取全部的訂單信息完成響應
