how to suspend job in quartz scheduler?
提问by Hemant Metalia
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 ??
嗨，我正在创建一个基于 cron 表达式执行类方法的应用程序。为此，我正在使用 spring 石英，其中我必须在我的 spring 文件中配置所有这些东西，它工作正常，并且作业正在根据 cron 表达式执行，但现在我想在基于 java 类的特定作业中暂停下一次执行关于用户从 UI 中的选择。那有没有办法做到这一点？？
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.
我可以在上下文中获取所有正在运行的作业的详细信息吗？如果是这样，那么我可以过滤作业并尝试暂停该作业以供下次执行。

Inject your SchedulerFactoryBean. Use it's getSchedulermethod to obtain a quartz Schedulerand use rescheduleJobor other methods from quartz API to perform your task.
注入您的SchedulerFactoryBean。使用它的getScheduler方法来获取一个quartz Scheduler并使用rescheduleJob或来自quartz API 的其他方法来执行您的任务。

I got it work by use of following code
我使用以下代码让它工作
stdScheduler is a scheduleFactoryBean
stdScheduler 是一个 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);
}
}
}

We can use the stdScheduler.pauseJob(JobKey jobKey) method to reduce the number of loops mentioned in the code above
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次数

If you got hold of the SchedulerFactoryBean by injection or somehow else there are the convenience methods:
如果您通过注入或其他方式获得了 SchedulerFactoryBean，则有一些方便的方法：
schedulerFactoryBean.getScheduler().standby();
schedulerFactoryBean.getScheduler().start();
When using Quartz directly also this works:
当直接使用 Quartz 时，这也有效：
@Autowired
private Scheduler scheduler;
...
scheduler.standby();
...
scheduler.start();
