Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone....解决方法

调用mysql时报错

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value '�й���׼ʱ��' 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.

解决办法: JDBC 的连接 url 部分加上 serverTimezone=UTC
