查询数据时发现一个bug，前端传了2021-12-28这个日期，转成String类型居然变成了2022-12-28.
经过各种排查，锁定问题可能出现在一个时间转换代码上
DateFormat formatter = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss");
经过百度发现YYYY代表的含义，和yyyy是不一样的
简单来说，一年有52周，超过52周的，年份+1，2021年有52个周，28号属于第53周，所以会出现年份+1
Java's DateTimeFormatter pattern "YYYY" gives you the week-based-year, (by default, ISO-8601 standard) the year of the Thursday of that week.
The unit that represents week-based-years for the purpose of addition and subtraction.
This allows a number of week-based-years to be added to, or subtracted from, a date. The unit is equal to either 52 or 53 weeks. The estimated duration of a week-based-year is the same as that of a standard ISO year at . 365.2425 Days
The rules for addition add the number of week-based-years to the existing value for the week-based-year field. If the resulting week-based-year only has 52 weeks, then the date will be in week 1 of the following week-based-year.
