大项目之网上书城（九）——订单Demo

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;

import java.util.ArrayList;

import java.util.List;

import java.util.UUID;

import cn.edu.bdu.mc.beans.Book;

import cn.edu.bdu.mc.daos.impls.OrderDaoImpl;

import cn.edu.bdu.mc.daos.impls.OrderitemDaoImpl;

import cn.edu.bdu.mc.services.OrderService;

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 {

		// TODO Auto-generated method stub

		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.setReciver_address(address);

		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 Order delById(String order_id) throws SQLException {

		// TODO Auto-generated method stub

		Order order = orderDao.delById(order_id);

		orderitemDao.delById(order_id);

		return order;

	}

	@Override

	public List<Order> findNotPayByUser_id(int user_id) throws SQLException {

		// TODO Auto-generated method stub

		return orderDao.findOrderByUser_id(user_id, 0);

	}

	@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 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 ;
