java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.
解决方案一:
url: jdbc:mysql://localhost:3306/demo?serverTimezone=GMT
解决方案二:
在MySQL安装目录中修改my.ini配置文件
添加 default-time-zone='+08:00'
重启MySQL服务
解决方案三:
mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name | Value |
+------------------+--------+
| system_time_zone | |
| time_zone | SYSTEM |
+------------------+--------+
mysql> set global time_zone = '+8:00';
