Exception in thread "main" java.sql.SQLException: The server time zone value '��������� - ����� ������ ����' 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 specifc time zone value if you want to utilize time zone support.

【问题讨论】：

你的 MySQL Spring Boot 是什么版本？

【参考方案1】：

我认为您需要明确设置服务器时区。可以通过JDBC URL设置。

例如-

jdbc:mysql://HOST:DB_PORT:/DB?serverTimezone=UTC
