Spring Cron表达式“ * * / 1 * * *?”的含义

标签: java spring cron

我是Spring和cron的新手,在我的代码中使用了以下表达式:“ * * / 1 * * *?”。我不知道这意味着什么。我已经在Google上搜索过,并在一些网站上尝试过此表达式:

它告诉我,这意味着“关闭 每分钟从小时后的00:00开始的第二分钟”,第二个站点告诉我“每小时的每一分钟。”但是与Bug的日志相关联,我不知道实际上是什么时候触发的。

以下是日志摘录:

如何运行“关闭 每分钟从小时后的00分钟开始”或“在每小时之后的每分钟开始。”我听不懂。您能帮我理解吗?

Spring cron expressionUnix cron expression之间有区别

春季cron:

second, minute, hour, day (of month), month, day (of week)

Unix-Cron:

minute, hour, day (of month), month, day (of week)

如果您每天都在寻找Spring表达式,请尝试以下操作:

"0 0 * * * *"
