课程名称：多端全栈项目实战：商业级代驾全流程落地
课程章节： 华夏代驾全栈小程序实战
课程讲师： 神思者
课程内容：
创建代驾订单，保存到mysql
课程收获：
接下来需要编写 insertOrder service类
int rows = orderDao.insert(orderEntity);
将传入的数据进行插入
之后判断rows的长度 如果是1则表示插入成功
这时候就要调用第二个sql 去查找刚才插入的订单的uuid
String id = orderDao.searchOrderIdByUUID(orderEntity.getUuid());
之后插入账单数据 （同时 需要把刚才订单的id一同传入）
billEntity.setOrderId(Long.parseLong(id));
rows = orderBillDao.insert(billEntity);
同样也是判断rows 长度为1 表示成功
之后只需要往redis里面插入缓存，配合redis事务用于司机抢单，避免多个司机同时抢单成功（也可以降低数据库的读写压力）
在redis 缓存 未接单的订单id 当订单有司机抢到后 就把司机id写入
如果没有人抢就用none
抢完订单后 需要把缓存销毁 同时更新sql 缓存设置超时15分钟 如果超过15分钟 订单则销毁
防止早上下单 司机晚上才抢（人都走了 hhh~~）
public String insertOrder(OrderEntity orderEntity, OrderBillEntity billEntity) {
//插入订单记录
int rows = orderDao.insert(orderEntity);
if (rows == 1) {
String id = orderDao.searchOrderIdByUUID(orderEntity.getUuid());
//插入订单费用记录
billEntity.setOrderId(Long.parseLong(id));
rows = orderBillDao.insert(billEntity);
if (rows == 1) {
//往Redis里面插入缓存，配合Redis事务用于司机抢单，避免多个司机同时抢单成功
redisTemplate.opsForValue().set("order#" + id, "none");
redisTemplate.expire("order#" + id, 15, TimeUnit.MINUTES); //缓存15分钟
return id;
} else {
throw new HxdsException("保存新订单费用失败");
}
} else {
throw new HxdsException("保存新订单失败");
}
}附上刚才说的代码
接下来需要编写form类 因为三个sql要传ing多参数的

@Schema(description = "超出基础返程里程的价格")
private String exceedReturnPrice;}经纬度在数据库里面是string
需要进行转换
JSONObject json = new JSONObject();
json.set("latitude", form.getStartPlaceLatitude());
json.set("longitude", form.getStartPlaceLongitude());
orderEntity.setStartPlaceLocation(json.toString());java里面浮点数不够精确所以也需要进行处理
orderEntity.setExpectsMileage(new BigDecimal(form.getExpectsMileage())); orderEntity.setExpectsFee(new BigDecimal(form.getExpectsFee())); orderEntity.setFavourFee(new BigDecimal(form.getFavourFee()));
接下来 就可以进行测试拉~~
