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01：
登录数据库，执行下面这2条命令：
show variables like '%time_zone%';
set global time_zone='+8:00';
解决方案02：
在数据库名后拼接如下设置：
?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL
例如：
spring:datasource:hikari:driver-class-name: com.mysql.cj.jdbc.Driverjdbc-url: jdbc:mysql://localhost:3306/数据库名?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8username: rootpassword: root
