mysql连接报错：The server time zone value '�й���׼ʱ��'

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.


解决方法：
在连接字符串后面加上时区设置：?serverTimezone=UTC，其中UTC是统一标准世界时间。
示例：
url: jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC
