没人会帮你写代码，你永远记住。多问一下业务而不是技术问题。

Today Dinner

1. bug：JSON parse error: Numeric value (693513511371800577) out of range of int (-2147483648 - 2147483647);：
   原因：List<UserDO> getUserByIds(Integer<Long> ids);中Integer范围太小了。
   

2. bug:Field orderFaceSheetBalanceQueryService in com.yida.controller.WarehouseSetupController required a bean of type 'com.yida.service.OrderFaceSheetBalanceQueryService' that could not be found.
原因：service层没有加注解问题：@Service。

3. mybatis中CASE...THEN的坑：有一次
   

4. 自己编写SQL的能力太差了。！！！
