How to I map DATETIME to Spring Boot?

[Stefan Jankovic]

So far I used MySQL's DATE data type, which I mapped like:

@Temporal(TemporalType.DATE)
private Date date = new Date();

I hoped that changing temporal's value from DATE to TIME would work. Unfortunately, it throws an exception. What can be done now? Is there an alternative?

P.S. Why I must keep part: new Date();? Shouldn't it be mapped to the current Date if I omit that field from Postman? If I omit it, I get null.

Why would it be set to current date?

Then what does @Temporal even do? Just formats Date object?

@Temporal tells JPA how to map generic date/time types like java.util.Date and I believe also java.util.Calendar to date, time or datetime columns. Other types like java.sql.Date, java.sql.Time, java.sql.Timestamp and classes from java.time already contain information to auto-guess the database type, but java.util.Date is so generic that it can be mapped to any of the three.

Stefan, you said you changed the value in @Temporal. Did you also change the actual database column type? Because the two must match. And if you want the date and time, you should use TIMESTAMP, not TIME. DATE is only the date part, TIME is only the time part, TIMESTAMP is both combined.
