Quartz provides a little tutorial on how to use cron expressions. If no cron expression is provided, the component uses a simple trigger. In cron expressions with an interval of /N, all values in the specified range that are intervals of N are used. However, if you want to launch the script every 10 minutes on the clock, no matter how long the last instance was running (or whether it still is running), you must execute the script in background and sleep in parallel by replacing the ; with an &:. CronTrigger Example 1 - an expression to create a trigger that simply fires every 5 minutes. Some examples of cron schedules: */5 * * * * * - runs every 5 seconds */10 * * * * - runs every 10 minutes; 0 6-20/2 * * 1-5 - runs every second hour between 6AM and 8PM on weekdays (Monday through Friday) 5 4 * * SUN - runs at 4:05 on every Sunday; Library testing.
