Error (jet lag) occurs when connecting MySQL Java

Error contents:

Exception in thread "main" 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.

Solution:
In DriverManager.getConnection ( "jdbc: mysql: // ip address (domain name) port number / database")
after the table name plus ?serverTimezone=UTC
such as: DriverManager.getConnection ( "jdbc: mysql: // localhost:? 3306 / database serverTimezone = UTC "," username "," password ");
