Exception in thread “main“ java.sql.SQLException: The server time zone value ‘�й���׼ʱ��‘ is unrecogn

在java练习JDBC时，连接数据库发现

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.

经过冲浪，发现是系统时间错误。
需要在访问数据库的url中加上下面语句

?serverTimezone=GMT%2B8

拿我个人的例子来说
初始代码：

 String url = "jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=utf8&useSSL=true";

改正之后的代码

 String url = "jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=utf8&useSSL=true&serverTimezone=GMT%2B8";

即加上了&serverTimezone=GMT%2B8。
