如何在Grails中从控制器设置cron作业的cron表达式

Question

I want to get a cron expression from a user through .gsp and want to set it as new cron expression of Dynamic Job from controller. Intially my cron expression was like "0 1 0 * * ?" but now want to change it to.. say

String cronExpression="0 2 0 * * ?"  // in the controller

// creates cron trigger;

DynamicJob.schedule(String cronExpression, Map params?)

but it doesn't work.

Answer 1

Something like this maybe:

trigger.cronExpression = params.cronexpression
quartzScheduler.rescheduleJob(new TriggerKey(params.triggerName, params.triggerGroup), trigger)

For more context see this controller in Quartz Monitor plugin or just use the plugin itself .
