The server time zone value ‘�й���׼ʱ��‘ is unrecognized or represents more than one time zone......

spark写入mysql报错如下

Caused by :com.mysql.cj.exceptions.InvalidConnectionAttributeException: 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.

问题原因

时区问题（高版本的MySQL在连接时需要设置时区）

解决方法

在url中添加 serverTimezone=GMT%2B8，如下

"jdbc:mysql://localhost:3306/database?serverTimezone=GMT%2B8"
