Cause: java.sql.SQLException: The server time zone value ‘???ú±ê×??±??’ 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.
弄ibatis的时候报了个错，主要报错是上面的样子。
猜测是时区问题server time zone value，毕竟直接提示了。
然后百度–》csdn，找到了解决方法 ?serverTimezone=UTC
问题解决。
ps：mysql的驱动问题在8点几的版本后需要将驱动写为com.mysql.cj.jdbc.Driver
