报错：

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

serverTimezone=UTC”不然会因为时区问题报错，这里用了CTT中国*时区避免产生8小时时差

解决方案：

 url: jdbc:mysql://localhost:3306/person?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true
