红帽全球峰会269.8. 使用 Cron Triggers
Quartz 支持类似于 Cron 的表达式，以方便的格式指定计时器。您可以在 cron URI 参数中使用这些表达式；尽管保留有效的 URI 编码，我们允许使用 + 而不是空格。Quartz 提供了一些关于 如何使用 cron 表达式的教程。
例如，以下命令将每五分钟每五分钟执行一次从 12pm （下午）到下午 6pm 到下午 6pm 的消息：
from("quartz://myGroup/myTimerName?cron=0+0/5+12-18+?+*+MON-FRI").to("activemq:Totally.Rocks");
from("quartz://myGroup/myTimerName?cron=0+0/5+12-18+?+*+MON-FRI").to("activemq:Totally.Rocks");等同于使用 cron 表达式
0 0/5 12-18 ? * MON-FRI
0 0/5 12-18 ? * MON-FRI下表显示了我们用来保留有效 URI 语法的 URI 字符编码：
| URI Character | Cron 字符 |
|---|---|
|
| 空格 |
