MySQL報錯：The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

二、緣由：數據庫和系統時區差別形成的

三、解決方法

3.1 鏈接url（jdbc:mysql://localhost:3306/scaffold?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true&failOverReadOnly=false）後面加serverTimezone=GMT便可解決問題，若是須要使用gmt+8時區，須要寫成GMT%2B8，不然會被解析爲空。

3.2 使用低版本的MySQL jdbc驅動，5.1.28不會存在時區的問題
