小说网站订单管理ssm代码

这里提供一个基于SSM框架的小说网站订单管理的代码示例，供参考：

1. 创建订单实体类Order：

public class Order {
    private int orderId; // 订单ID
    private int userId; // 用户ID
    private int bookId; // 图书ID
    private String status; // 订单状态

    // 省略getter和setter方法
}

2. 创建订单管理的Service接口和实现类：

public interface OrderService {
    void addOrder(Order order); // 添加订单
    void approveOrder(int orderId); // 审核订单
    void deliverOrder(int orderId); // 发货
    void returnOrder(int orderId); // 退货
    Order queryOrder(int orderId); // 查询订单
}

@Service
public class OrderServiceImpl implements OrderService {

    @Autowired
    private OrderMapper orderMapper;

    @Override
    public void addOrder(Order order) {
        orderMapper.addOrder(order);
    }

    @Override
    public void approveOrder(int orderId) {
        Order order = orderMapper.queryOrder(orderId);
        if (order != null) {
            order.setStatus("已审核");
            orderMapper.updateOrder(order);
        }
    }

    @Override
    public void deliverOrder(int orderId) {
        Order order = orderMapper.queryOrder(orderId);
        if (order != null && order.getStatus().equals("已审核")) {
            order.setStatus("已发货");
            orderMapper.updateOrder(order);
        }
    }

    @Override
    public void returnOrder(int orderId) {
        Order order = orderMapper.queryOrder(orderId);
        if (order != null && order.getStatus().equals("已发货")) {
            order.setStatus("已退货");
            orderMapper.updateOrder(order);
        }
    }

    @Override
    public Order queryOrder(int orderId) {
        return orderMapper.queryOrder(orderId);
    }
}

3. 创建订单管理的Mapper接口和XML文件：

public interface OrderMapper {
    void addOrder(Order order); // 添加订单
    void updateOrder(Order order); // 更新订单
    Order queryOrder(int orderId); // 查询订单
}

<!-- OrderMapper.xml -->
<mapper namespace="com.example.mapper.OrderMapper">
    <insert id="addOrder" parameterType="com.example.entity.Order">
        insert into orders(user_id,book_id,status) values(#{userId},#{bookId},#{status})
    </insert>

    <update id="updateOrder" parameterType="com.example.entity.Order">
        update orders set status=#{status} where order_id=#{orderId}
    </update>

    <select id="queryOrder" parameterType="int" resultType="com.example.entity.Order">
        select * from orders where order_id=#{orderId}
    </select>
</mapper>

4. 创建订单管理的Controller：

@Controller
@RequestMapping("/order")
public class OrderController {

    @Autowired
    private OrderService orderService;

    // 添加订单
    @RequestMapping("/add")
    public String addOrder(Order order) {
        orderService.addOrder(order);
        return "redirect:/book/detail/" + order.getBookId();
    }

    // 审核订单
    @RequestMapping("/approve/{orderId}")
    public String approveOrder(@PathVariable int orderId) {
        orderService.approveOrder(orderId);
        return "redirect:/admin/order/list";
    }

    // 发货
    @RequestMapping("/deliver/{orderId}")
    public String deliverOrder(@PathVariable int orderId) {
        orderService.deliverOrder(orderId);
        return "redirect:/admin/order/list";
    }

    // 退货
    @RequestMapping("/return/{orderId}")
    public String returnOrder(@PathVariable int orderId) {
        orderService.returnOrder(orderId);
        return "redirect:/admin/order/list";
    }

    // 查询订单
    @RequestMapping("/detail/{orderId}")
    public String queryOrder(@PathVariable int orderId, Model model) {
        Order order = orderService.queryOrder(orderId);
        model.addAttribute("order", order);
        return "orderDetail";
    }
}

以上代码实现了订单的添加、审核、发货、退货和查询功能。可以根据具体项目需求进行修改和扩展。
