当Jdbc链接出现如下错误时：

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.

这个乱码了，jdbc无法解析：通过以下方式

1： 在链接字符串后面加上?serverTimezone=UTC，表示标准时间格式
2：?useUnicode=true&characterEncoding=UTF-8，采用utf8格式，解决乱码
