mysql出现The server time zone value '�й���׼ʱ��' is unrecognized 记录

java.sql.SQLException: 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：

url后面增加：

jdbc.url=jdbc:mysql://localhost:3306/choosecourse?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false

试了很多次这个方法都不管用后来直接修改了时区。
修改数据库时区：

set global time_zone = '+8:00'; ##修改mysql全局时区为北京时间，即我们所在的东8区
set time_zone = '+8:00'; ##修改当前会话时区
flush privileges; #立即生效
