In a java web application (servlets/spring mvc), using tomcat, is it possible to run a cron job type service?
e.g. every 15 minutes, purge the log database.
Can you do this in a way that is container independent, or it has to be run using tomcat or some other container?
Please specify if the method is guaranteed to run at a specific time or one that runs every 15 minutes, but may be reset etc. if the application recycles (that’s how it is in .net if you use timers)
As documented in Chapter 23. Scheduling and Thread Pooling, Spring has scheduling support through integration classes for the
Timerand the Quartz Scheduler (http://www.quartz-scheduler.org/). For simple needs, I’d recommend to go with the JDKTimer.Note that Java schedulers are usually used to trigger Java business oriented jobs. For sysadmin tasks (like the example you gave), you should really prefer cron and traditional admin tools (bash, etc).
