1、解決方法：

報錯信息為:

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'ÖÐ¹ú±ê×¼Ê±¼ä' 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.

此問題為時區問題,在 JDBC 的連接 url 部分加上 serverTimezone=UTC 即可。
