大项目之网上书城（九）——订单Demo
主要改动
加了创建订单，为订单付款，删除订单。
1.OrderServiceImpl
代码
有添加、删除、付款、根据是否付款查找。还加了添加收货信息登记。
package cn.edu.bdu.mc.services.impls;
import java.sql.SQLException;

public class OrderServiceImpl implements OrderService {
private OrderDao orderDao = new OrderDaoImpl();
private OrderitemDao orderitemDao = new OrderitemDaoImpl();
private BookDao bookDao = new BookDaoImpl();
@Override
public boolean addOrder(String order_id, int user_id, String name, String address, String phone, String[] book_ids) throws SQLException {

List<Book>books = new ArrayList<Book>();
for (String book_id : book_ids) {
Book book = bookDao.findBookById(Integer.parseInt(book_id));
books.add(book);
//如果数量不够了就本次购买失败
if(book.getCount()==0) {
return false;
}
}
Order order = new Order();
order.setUser_id(user_id);
order.setReciver_name(name);
order.setReciver_phone(phone);

order.setOrder_id(order_id);
orderDao.addOrder(order);
for (Book book : books) {
Orderitem orderitem = new Orderitem();
orderitem.setBook_id(book.getBook_id());
orderitem.setOrder_id(order_id);
orderitem.setCount(1);
orderitem.setPrice(book.getPrice());
book.setCount(book.getCount()-1);
bookDao.update(book);
orderitemDao.addOrderitem(orderitem);
}
return true;
}
@Override
public void AfterPay(String order_id) throws SQLException {
Order order = orderDao.findOrderById(order_id);
order.setPaystate(1);
orderDao.update(order);
}

}
@Override
public List<Order> findAreadyPayByUser_id(int user_id) throws SQLException {
// TODO Auto-generated method stub
return orderDao.findOrderByUser_id(user_id, 1);
}
}
2.OrderDaoImpl
代码
目前有添加、删除、根据order_id查找和根据user_id查找
package cn.edu.bdu.mc.daos.impls;
import java.sql.SQLException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import javax.sql.DataSource;
import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;
import org.apache.commons.dbutils.handlers.BeanListHandler;
import cn.edu.bdu.mc.beans.Order;
import cn.edu.bdu.mc.daos.OrderDao;
import cn.edu.bdu.mc.utils.JDBCUtil;
public class OrderDaoImpl implements OrderDao {
private DataSource dataSource = JDBCUtil.getDataSource();
private QueryRunner queryRunner = new QueryRunner(dataSource);
@Override
public void addOrder(Order order) throws SQLException {
// TODO Auto-generated method stub
String sql = "insert into `order`(user_id,order_id,reciver_name,reciver_phone,reciver_address,paystate,money,order_time) values(?,?,?,?,?,0,0,?)";
Date date = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss");
String date1 = dateFormat.format(date);
queryRunner.update(sql,order.getUser_id(),order.getOrder_id(),order.getReciver_name(),order.getReciver_phone(),order.getReciver_address(),date1);
}
@Override
public void update(Order order) throws SQLException {
// TODO Auto-generated method stub
String sql = "update `order` set user_id = ?,reciver_name = ?,reciver_phone = ?,reciver_address = ?,paystate = ?,money = ?,order_time = ?";
queryRunner.update(sql,order.getUser_id(),order.getReciver_name(),order.getReciver_phone(),order.getReciver_address(),order.getPaystate(),order.getMoney(),order.getOrder_time());
}
@Override
public Order findOrderById(String order_id) throws SQLException {
// TODO Auto-generated method stub
String sql = "select * from `order` where order_id = ?";
return queryRunner.query(sql, new BeanHandler<Order>(Order.class), order_id);
}
@Override
public Order delById(String order_id) throws SQLException {
Order order = findOrderById(order_id);
String sql = "delete from `order` where order_id = ?";
queryRunner.update(sql, order_id);
return order;
}
@Override
public List<Order> findOrderByUser_id(int user_id, int paystate) throws SQLException {
// TODO Auto-generated method stub
String sql = "select * from `order` where user_id = ? and paystate = ?";
return queryRunner.query(sql, new BeanListHandler<Order>(Order.class), user_id, paystate);
}
}
3.OrderitemDaoImpl
代码
目前有添加和删除
package cn.edu.bdu.mc.daos.impls;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.apache.commons.dbutils.QueryRunner;
import cn.edu.bdu.mc.beans.Orderitem;
import cn.edu.bdu.mc.daos.OrderitemDao;
import cn.edu.bdu.mc.utils.JDBCUtil;
public class OrderitemDaoImpl implements OrderitemDao {
private DataSource dataSource = JDBCUtil.getDataSource();
private QueryRunner queryRunner = new QueryRunner(dataSource);
@Override
public void addOrderitem(Orderitem orderitem) throws SQLException {
// TODO Auto-generated method stub
String sql = "insert into orderitem values (?,?,?,?)";
queryRunner.update(sql,orderitem.getOrder_id(),orderitem.getBook_id(),orderitem.getCount(),orderitem.getPrice());
}
@Override
public void delById(String order_id) throws SQLException {
// TODO Auto-generated method stub
String sql = "delete from `order` where order_id = ?";
queryRunner.update(sql, order_id);
}
}
4.orderitem_insert触发器
代码
orderitem中每增加一项，将他对应的order_id的订单的钱增加上他的书的价格乘以数量。
DROP TRIGGER IF EXISTS `orderitem_insert`;
DELIMITER ;;
CREATE TRIGGER `orderitem_insert` AFTER INSERT ON `orderitem` FOR EACH ROW begin
update `order` set money = money + new.price * new.count where order_id = new.order_id;
end
;;
DELIMITER ;5.DelOrderServlet
