java.sql.SQLException: The server time zone value '?й???????'

描述：

Error querying database.  Cause: java.sql.SQLException: 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：在连接数据库的url后增加serverTimezone=UTC字段，即：

dbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
