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.
解决如下:
添加时区:&serverTimezone=UTC
url: jdbc:mysql://localhost:3306/orderingsystem?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
