> hello > According to your screenshot, the short time you choose is 2020-04-27 23:56:00 to 2020-04-27 23:56:02 > cron expression is 0 0 * * *? *, It can be judged that the cron expression is executed once every hour. Then, according to your start time, the next execution time should be 2020-04-28 00:00:00, and your end time period is 2020-04-27 23:56:02, which is less than the next execution time . So adding Quartz job will fail. That is, the online failed. > > **Solution** > 1 You can adjust the end time period. Just include the next execution time of cron within the start and end time period. > > 2 When modifying the timing, set the "execution time" button to calculate the next five execution times. If there is data, the timing setting is correct, otherwise there is a problem with the timing setting. > > 根据你的截图，你选的时间短是2020-04-27 23:56:00 到 2020-04-27 23:56:02 > cron 表达式为 0 0 * * * ? *,可以判断cron表达式是一小时执行一次。如果按照你的的开始时间，下一次执行执行时间应该是2020-04-28 00:00:00，而你的结束时间段是 2020-04-27 23:56:02 ，小于下一次执行时间。所以添加Quartz job就会失败。也就是上线失败。 > > **解决办法** > 1 你可以调整结束时间段。只要要包含cron下一次执行时间在起止时间段内。 > > 2 在修改定时，单击“执行时间”按钮，可以计算接下来五次执行时间，如果有数据那么定时设置正确，否则定时设置就有问题。 > >  I'm not sure if this is a bug and will be updated in a later release to address this issue. If I only want to do it once at a certain point in time, this setup is a bit repetitive（不确定这是否属于bug，后续版本是否会针对这个问题进行更新。 如果我只想在某一时间点执行一次，这设置就有点重复了） ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
