在使用spring JDBC 连接数据库时出现的错误：
Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value ‘?й???????‘ 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.

解决办法：在setUrl 数据库后面添加：
?serverTimezone=UTC
【坑】The server time zone value '?й???????' is unrecognized or represents more than one time zone.
