對於使用JDBC連接mysql數據時The server time zone value '¤¤°ê¼Ð·Ç®É¶¡'...的異常問題解決。

相信很多小伙伴和我一樣遇到了這類問題，在使用JDBC連接mysql資料庫的時候發生SQLException如下所示的異常情況！

java.sql.SQLException: The server time zone value '¤¤°ê¼Ð·Ç®É¶¡' 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.

這其實是由於在安裝的時候沒有選擇使用位置，mysql預設使用美國時間，所以得改成我們東八區的時間。

所以應該怎麼做呢？

首先網上有很多方法是更改資料庫中的 time_zone，如下圖：

這個方法只能是解決這一次問題，重啟之後依然會報錯，還需要再次更改。

最好的方法就是在jdbc配置中添加?serverTimezone=UTC到末尾。

如下圖所示：
