使用MySQL时出现The server time zone value '�й���׼ʱ��' is unrecogni的解决方法

问题：

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：
在mysql配置的url后面加上：&serverTimezone=UTC，例如
jdbc:mysql://127.0.0.1:3306/face?autoReconnect=true&useSSL=false&useUnicode=true&characterEncoding=UTF8&serverTimezone=UTC
