    大项目之网上书城（九）——订单Demo

    目录

    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.beans.Order;
import cn.edu.bdu.mc.beans.Orderitem;
import cn.edu.bdu.mc.daos.BookDao;
import cn.edu.bdu.mc.daos.OrderDao;
import cn.edu.bdu.mc.daos.OrderitemDao;
import cn.edu.bdu.mc.daos.impls.BookDaoImpl;
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 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 ;
