从云端运行应用程序时遇到以下错误，但从本地运行时不会出现此错误。

也尝试过以下设置，但它仍然采用 CST 时区。 浏览了下面提到的多篇文章，但主要讨论的配置仅与 postgre 相关。

为 jdbc 连接字符串设置 serverTimezone，如下所示。

jdbc:mysql://localhost:3306/test?serverTimezone=UTC

postgre 的当前时区也是 UTC。 以下是用于在 postgre 上显示和设置时区的命令

SHOW TIMEZONE
SET TIMEZONE 'UTC'

Answer 1

没有

serverTimezone

参数，因此驱动程序正在使用为 JVM 配置的时区。如果您不想更改它，可以尝试为服务器进程设置

timezone

参数：

jdbc:mysql://localhost:3306/test?options=-ctimezone=UTC
