如何在石英调度程序中暂停工作？

Question

Hi i am creating an application that executes the method of a class based on a cron expression. For that i am using spring quartz in which i have to configure all these stuffs in my spring-file it works fine and jobs are executing based on the cron expression, But now i want to suspend the next execution of particular job in java class based on the choice of a user from UI. Then is there any way to do this ??

can i get the details of all running job it the context ? if so then i can filter the jobs and try to suspend that job for next execution.

Answer 1

Inject your SchedulerFactoryBean . Use it's getScheduler method to obtain a quartz Scheduler and use rescheduleJob or other methods from quartz API to perform your task.

Answer 2

I got it work by use of following code

stdScheduler is a scheduleFactoryBean

 String groupnames[] = stdScheduler.getJobGroupNames();
 for (String groupName : groupnames) {
     String[] jobNames = stdScheduler.getJobNames(groupName);
     for (String jobName : jobNames) {
            if (jobName.equals("jobName")) {
                    stdScheduler.pauseJob(jobName, groupName);
            }
     }
 }          

Answer 3

我们可以使用stdScheduler.pauseJob（JobKey jobKey）方法来减少上面代码中提到的循环数

Answer 4

If you got hold of the SchedulerFactoryBean by injection or somehow else there are the convenience methods:

schedulerFactoryBean.getScheduler().standby();
schedulerFactoryBean.getScheduler().start();

When using Quartz directly also this works:

@Autowired
private Scheduler scheduler;

...
scheduler.standby();
...
scheduler.start();
