我正在每分钟使用Quartz插件进行Grails同步工作，但是我无法使用0 * * * * *定义，并且抛出了一些异常:

Error loading plugin manager: Unable to locate constructor with Class parameter for class grails.plugins.quartz.DefaultGrailsJobClass (NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

Caused by: java.lang.IllegalArgumentException: Cron expression '0 * * * * *' in the job class cl.ionix.softoken.jobs.SendRefreshStatusByMinuteJob is not a valid cron expression

最佳答案

您可以使用此:

0 0/1 * * * ?

Either Day-of-Week or Day-of-Month must be "?", or you will get an error since support by the underlying library is not complete. So you can't specify both fields, nor leave both as the all values wildcard "*"; this is a departure from the unix crontab specification.
