打开CMD
将工作目录切换到MySQL的bin下
cd F:\mysql-5.7.21-winx64\bin
mysql -u root -p
输入密码即可登陆MySQL
select now(); 查看mysql系统时间。和当前时间做对比
set global time_zone = '+8:00'; 设置时区更改为东八区
flush privileges; 刷新权限
如果不设置默认时区,会出现以下异常:
Caused by: 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.
