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

启动SpringBoot报：

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.

说明：

1.使用的驱动是8.0但是你的数据库是5.0的就报出这样的了

解决：

1.加入：?serverTimezone=GMT%2B8

url: jdbc:mysql://localhost:3306/base_system?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8

2.或者修改数据库：

 vi /etc/mysql/my.cnf
 然后在mysqld下边的配置中添加一行：
 default-time_zone = '+8:00'
 然后重启mysql
 service mysql restart`
