How to Properly Store Java Date and Time in MySQL's datetime Column Using JPA?

Storing Java Date with Time in MySQL datetime Using JPA

In JPA, mapping Java Date to MySQL datetime requires consideration of time information. While date information is typically stored correctly, time often remains as 00:00:00 due to a mismatch in date formats.

To rectify this issue, it is recommended to convert the Java Date to a String representation in the desired MySQL datetime format. This can be achieved using the SimpleDateFormat class. An example code snippet demonstrating this conversion is:

import java.text.SimpleDateFormat;
import java.util.Date;

Date dt = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String currentTime = sdf.format(dt);

By converting the Java Date to the String 'currentTime' in the correct datetime format, it can be inserted into the MySQL datetime column.

This solution ensures that both date and time information are stored accurately in the database. It is important to note that the database column type must be set as DATETIME to accommodate both date and time values.
