Grails - 停止或重新安排工作

问题描述

我以这种方式动态调度作业：
$ b

JobClass.schedule（Long interval，Integer repeatCount，Map params） $ b $ p

稍后，我想停止运行作业，然后根据用户操作重新启动它们。

我怎么能阻止这个触发器？

确实停止它的唯一方法是 JobClass.removeJob（） $ b

谢谢！

class =h2_lin>解决方案

您可以使用具有方法unscheduleJob的Scheduler类，它只删除所有与作业绑定的触发器。对于调度程序类对象：



服务中注入



  def jobManagerService 
  

使用代码取消计划作业



 jobManagerService.getQuartzScheduler（）。unscheduleJob（TriggerKey triggerkey）
  

开始作业调度：只需为同一作业创建一个新的触发器并安排它。

 触发器触发器= TriggerBuilder.newTrigger（） 
 .withIdentity（triggerName，triggerGroupName）
 .withSchedule（SimpleScheduleBuilder.simpleSchedule（）
 .withIntervalInSeconds（））
 .forJob（JobKey.jobKey（jobName，groupName））
 .build（）
 
 jobManagerService.getQuartzScheduler（）。scheduleJob（trigger）; 
  

I am dynamically scheduling jobs, at this way:

JobClass.schedule(Long interval, Integer repeatCount, Map params )

Later I want to stop the job from running, and then restart them again according to the users actions.

How could I stop this trigger?

The only way that did actually stop it was JobClass.removeJob(), but I wasn;t able to start it again later, so I need something else.

Thanks!

解决方案

you can use Scheduler class having methods unscheduleJob which just delete all the triggers bind with the job. For scheduler class object:

Inject in service

def jobManagerService

use the code to unschedule the job

jobManagerService.getQuartzScheduler().unscheduleJob(TriggerKey triggerkey)

to start the job scheduling: just create a new trigger for the same job and schedule it.

Trigger trigger = TriggerBuilder.newTrigger()
                .withIdentity(triggerName, triggerGroupName)
                .withSchedule(SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds())
                .forJob(JobKey.jobKey(jobName, groupName))
                .build()

        jobManagerService.getQuartzScheduler().scheduleJob(trigger);
