需求分析以及接口设计

技术细节

1.Controller层:

/**
     * 接单
     * @param orderConfirmDTO
     * @return
     */
    @ApiOperation("接单")
    @PutMapping("/confirm")
    public Result confirm(@RequestBody OrdersConfirmDTO orderConfirmDTO){
        log.info("接单,{}",orderConfirmDTO);
        orderService.confirm(orderConfirmDTO);
        return Result.success();
    }

2.Service层:

public void confirm(OrdersConfirmDTO orderConfirmDTO) {
        Orders orders = new Orders();
        orders.setId(orderConfirmDTO.getId());
        orders.setStatus(Orders.CONFIRMED);
        //更新此订单
        orderMapper.update(orders);
    }

3.Mapper层:

<update id="update" parameterType="com.sky.entity.Orders">
        update orders
        <set>
            <if test="cancelReason != null and cancelReason!='' ">
                cancel_reason=#{cancelReason},
            </if>
            <if test="rejectionReason != null and rejectionReason!='' ">
                rejection_reason=#{rejectionReason},
            </if>
            <if test="cancelTime != null">
                cancel_time=#{cancelTime},
            </if>
            <if test="payStatus != null">
                pay_status=#{payStatus},
            </if>
            <if test="payMethod != null">
                pay_method=#{payMethod},
            </if>
            <if test="checkoutTime != null">
                checkout_time=#{checkoutTime},
            </if>
            <if test="status != null">
                status = #{status},
            </if>
            <if test="deliveryTime != null">
                delivery_time = #{deliveryTime}
            </if>
        </set>
        where id = #{id}
    </update>
