在連接字符串后面加上?serverTimezone=UTC

其中UTC是統一標准世界時間。

完整的連接字符串示例：jdbc:mysql://localhost:3306/test?serverTimezone=UTC

或者還有另一種選擇：jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8，這個是解決中文亂碼輸入問題，當然也可以和上面的一起結合：jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
