MyBatis连接MySQL错误

MySQL数据库版本8.0

参考网上例子连接数据库总是失败，错误提示千奇百怪。。。

Exception in thread "main" 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.

最后解决方法。。。

在jdbc.properties中配置如下

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=Hongkong&useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

注意url中新增的参数。。。

一个是useSSL=false

一个是serverTimezone=Hongkong
