The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone.

MySql运行报The server time zone value ‘Öйú±ê׼ʱ¼ä’ is unrecognized or represents more than one time zone.的解决方法.
如果你的MySql没有配置环境变量的话可以先配置环境变量
计算机(我的电脑)----右键----属性----高级系统设置----环境变量

复制你的MySql的bin目录的路径,例如:E:\develop\MySql\bin

打开黑窗口
输入命令:mysql -uroot -p123456

输入命令:show variables like ‘%time_zone%’;

输入命令:set global time_zone=’+8:00’;

如果是SpringBoot中运行报错的:

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: 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.

可以将数据库中的连接信息:
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8修改为:
spring.datasource.url=jdbc:mysql://localhost:3306/test?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf-8 也可.
