The server time zone value ‘�й���׼ʱ��‘ is unrecognized or represents more than one time zone.

报错原因是因为数据库时区问题

Mysql Connector/J 6.x以上的版本，就报了时区的错误

 

在数据库连接后面拼接下面的语句即可

&serverTimezone=UTC

 

url: jdbc:mysql://localhost:3306/oneself?useUnicode=true&characterEncoding=UTF8&useSSL=false&serverTimezone=UTC
