Is there any way for solving the known problem in Spring Boot when connection to a MySQL database with middle-european time zone?

Question

In Spring Boot, when connecting to a Database from MySQL , i get the following Error:

2021-02-11 20:50:56.204 ERROR 22892 --- [           main] com.zaxxer.hikari.pool.HikariPool        : HikariPool-1 - Exception during pool initialization.

java.sql.SQLException: The server time zone value 'Mitteleurop�ische Zeit' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specific time zone value if you want to utilize time zone support.

Well, the error occurs, because I live in the european timezome, and it seems like, that there is a not supported character inside the name of this one. Is there any way for changing it? Or maybe any solution, so that I can still be in my actual timezone?

Answer 1

I think there are two solutions:

• set timezone for connection: in connection url set wanted timezone (like this jdbc:mysql://localhost:64356/test?serverTimezone=UTC )
• fix timezone in mysql config SET GLOBAL time_zone = 'UTC';

I preferer to always use UTC timezone between database and application.

Answer 2

In my case it works using jdbc:mysql://localhost:3306/test?useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=Europe/Berlin

But it depends on your OS. This solution applies to Ubuntu.

Answer 3

Problem solved:

I just entered in the MySQL-Terminal the following Query:

SELECT NOW();

SET GLOBAL time_zone = '-6:00';

This changes the time zone from System to user-defined.
