报的错误信息:ava.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.

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver 本来用的 com.mysql.jdbc.Driver报了警告,因此更改。
原因:
连接数据中时区错误原因
解决:
加上 serverTimezone=UTC
这里用了CTT中国台湾时区避免产生8小时时差
