数据后台管理（三）订单管理

1.查询所有订单信息

1.1查看显示订单的前端页面需要哪些订单信息

根据下面的orders-list.jsp页面的部分代码可以知道订单的信息表中不仅需要订单的id,orderNum,orderTimeStr,orderStatusStr，还需要的产品的productName,productPrice。因此在查询订单的信息时需要将该订单的产品信息也要查询出来并封装到Orders类中。

1.2在domain包下新建Orders类

该类中不仅包含orders表中基本的字段信息，还新增了orderTimeStr，orderStatusStr，product，travellers，member。

由于Date类型的无法在前端页面正常显示因此新增了orderTimeStr类，在get方法中将orderTime转换成字符串形式。由于orders表中orderStatus只是0或1，而前端页面需要具体的订单状态“关闭”或“开启”，因此在get方法中将orderStatus的0或1转换成orderStatusStr的“关闭”或开启。product是根据orders表中的productId从product表中查出的，并将其封装到该类的product中。
