使用MySQL的jdbc驅動關於時區引發的問題

連線資料庫異常如下：
### Cause: java.sql.SQLException: 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. at

原因是：
在使用mysql的jdbc驅動最新版（6.0+）時，遇到資料庫和系統時區差異引起的問題。
使用的資料庫是MySQL，驅動是8.0.12，這是由於資料庫和系統時區差異所造成的，在jdbc連線的url後面加上serverTimezone=GMT即可解決問題，如果需要使用gmt+8時區，需要寫成GMT%2B8，否則會被解析為空。再一個解決辦法就是使用低版本的MySQL jdbc驅動，5.1.28不會存在時區的問題。
