Quartz 简单触发器 vs cron 触发器
Quartz simple trigger vs cron trigger
对于我的企业应用程序，我需要按时间间隔进行批处理操作。
在提到石英调度器时，有两种类型。一种是简单触发器，另一种是 cron 触发器。
我对这些概念感到困惑。请用简单的例子解释一下。
请参考文档中给出的示例。
CronTrigger
CronTrigger is often more useful than SimpleTrigger, if you need a job-firing schedule that recurs based on calendar-like notions, rather than on the exactly specified intervals of SimpleTrigger.
一些例子
“every Friday at noon” or “every weekday and 9:30 am”, or even “every 5 minutes between 9:00 am and 10:00 am on every Monday, Wednesday and Friday during January”,.
CronTrigger Example 1 - an expression to create a trigger that simply fires every 5 minutes
“0 0/5 * * * ?”
CronTrigger Example 2 - an expression to create a trigger that fires every 5 minutes, at 10 seconds after the minute (i.e. 10:00:10 am, 10:05:10 am, etc.).
“10 0/5 * * * ?”
CronTrigger Example 3 - an expression to create a trigger that fires at 10:30, 11:30, 12:30, and 13:30, on every Wednesday and Friday.
“0 30 10-13 ? * WED,FRI”
CronTrigger Example 4 - an expression to create a trigger that fires every half hour between the hours of 8 am and 10 am on the 5th and 20th of every month. Note that the trigger will NOT fire at 10:00 am, just at 8:00, 8:30, 9:00 and 9:30
“0 0/30 8-9 5,20 * ?”
