# 错误信息 #

应用在启动过程中，在连接数据库阶段报错，关键错误信息如下：

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.

# 原因分析 #

如果你的数据库驱动（mysql-connector-java）版本过高（如：8.0.21），而数据库版本较低（如：5.7.12），就会出现这种情况。

# 解决方法 #

在jdbc连接后面加上`serverTimezone=UTC`， UTC是统一标准世界时间  
url: jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC

You must configure either the server or JDBC driver(via the ‘serverTimezone‘ configuration property)
