将日历添加到数据库后更改日期

Question

When I try to add new time entry to my db application first days was changed and destroy hierarchy. First two days of my week was changed.

I try to change time zone from CET to UTC and CEST

When I Post days from 25 - 31 days in DB return:

2019-03-25
2019-03-25
2019-03-27
2019-03-28
2019-03-29
2019-03-30
2019-03-31

But next when I use postman to get this week it's return:

{

    "day": "SUNDAY",
    "date": "2019-03-24",
    "hours": 0,
    "status": "SAVED",
    "comment": ""
},
{
    "day": "SUNDAY",
    "date": "2019-03-24",
    "hours": 5,
    "status": "REJECTED",
    "comment": ""
},
{
    "day": "MONDAY",
    "date": "2019-03-25",
    "hours": 9,
    "status": "REJECTED",
    "comment": ""
},
{
    "day": "TUESDAY",
    "date": "2019-03-26",
    "hours": 9,
    "status": "SAVED",
    "comment": ""
},
{
    "day": "WEDNESDAY",
    "date": "2019-03-27",
    "hours": 9,
    "status": "SAVED",
    "comment": ""
},
{
    "day": "THURSDAY",
    "date": "2019-03-28",
    "hours": 9,
    "status": "SAVED",
    "comment": ""
},
{
    "day": "FRIDAY",
    "date": "2019-03-29",
    "hours": 9,
    "status": "SAVED",
    "comment": ""
}

My DB driver is :

DATABASE_URL=jdbc:mysql://localhost:3306/restdb?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=CET

Answer 1

Use the correct data types.

DATE

In MySQL, your table column should be of type DATE .

This type is akin to the SQL-standard type DATE for date-only values without time-of-day and without time zone.

LocalDate

Retrieve your date string value as a LocalDate , as shown on Stack Overflow many many times already.

The LocalDate class has no time zone, so you should see no adjustments.

LocalDate.parse( "2019-01-23" )

Or:

LocalDate ld = myResultSet.getObject( date_col , LocalDate.class ) ;
