jdbc連接MySQL報以下錯誤處理方案

連接MySQL數據庫時報以下更改驅動包位置
Loading class `com.mysql.jdbc.Driver'. 
This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. 
The driver is automatically registered via the SPI and manual loading of the driver class is generally 
unnecessary.

com.mysql.jdbc.Driver改為com.mysql.cj.jdbc.Driver繼續報下面的錯誤
連接MySQL數據庫時報以下時區錯誤信息：
Exception in thread "main" java.sql.SQLException: 
The server time zone value '?й???????' 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.

 解決方案：
為URL添加參數serverTimezone=UTC即可，這里的時區可以根據自己數據庫的設定來設置（GMT/UTC ）。
jdbc:mysql://localhost:3306/dbname?useUnicode=true&characterEncoding=UTF-8&useJDBCComp
liantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
