spring boot The server time zone value 'PDT' is unrecognized or represents more than one time zone.

spring boot啟動專案時,發現數據庫拋如下錯誤

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'PDT' 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.
