创建OrderController并提供用户下单方法

public class OrderController {@Autowiredprivate Orderservice orderservice;/*** 用户下单* @param ordersSubmitDTO* @return*/@PostMapping("/submit")@ApiOperation("用户下单")public Result<OrderSubmitVO> submit(@RequestBody OrdersSubmitDTO ordersSubmitDTO){log.info("用户下单,参数为：{}", ordersSubmitDTO);OrderSubmitVO orderSubmitVO = orderservice.submitOrder(ordersSubmitDTO);return Result.success(orderSubmitVO);}
}
创建OrderService接口
package com.sky.service;import com.sky.dto.OrdersSubmitDTO;
import com.sky.vo.OrderSubmitVO;public interface Orderservice {/*** 用户下单* @param ordersSubmitDTO* @return*/OrderSubmitVO submitOrder(OrdersSubmitDTO ordersSubmitDTO);
}创建OrderServiceImpl实现OrderService接口

}
创建OrderMapper接口和对应的xml映射文件
package com.sky.mapper;import com.sky.entity.Orders;
import org.apache.ibatis.annotations.Mapper;@Mapper
public interface OrderMapper {/*** 插入订单数据* @param orders*/void insert(Orders orders);
}
<?xml version="1.0" encoding="UTF-8" ?>

</mapper>
创建OrderDetailMapper接口和对应的xml映射文件
package com.sky.mapper;import com.sky.entity.OrderDetail;
import org.apache.ibatis.annotations.Mapper;import java.util.List;@Mapper
public interface OrderDetailMapper {/*** 批量插入订单明细数据* @param orderDetailList*/void insertBatch(List<OrderDetail> orderDetailList);

连接账户
在软件安装目录下打开命令行
启动服务获取IP
导入功能代码
没有营业执照无法真正支付，所以绕过支付，直接支付成功。
在微信小程序里的pay包下的index.js中将如下的代码注释掉
把原先注释掉的重定向解除
把OrderServiceImpl中的如下代码注释掉
在OrderServiceImpl中，写入如下代码
在OrderMapper中写入如下代码
@Update("update sky_take_out.orders set status = #{orderStatus},pay_status = #{orderPaidStatus} ,checkout_time = #{check_out_time} where id = #{id}")void updateStatus(Integer orderStatus, Integer orderPaidStatus, LocalDateTime check_out_time, Long id);在OrderServiceImp中的如下位置给全局变量赋值
