Question

Spring’s internal scheduling capability as of Spring 3, includes support for cron-type expressions, and this is very similar to Quartz’s cron trigger.

Is there any reason why one would want to integrate Quartz with Spring?

Answer 1

Yes, you will need quarz for example:

• if you need to add new jobs at runtime, or
• if you need to change the interval (cron expression) at runtime,
• if you need statistics about the jobs,
• …

in general: if you need more than simply runing a method at fixed time.
