如何从 Quartz 调度器中查询调度的作业? [英] How to query the scheduled jobs from Quartz scheduler?

问题描述

我的应用程序中有一个 Scheduler 对象，我使用 scheduleJob 方法向其中添加了 Job 对象.

I have a Scheduler object in my application and I add Jobs to it using the scheduleJob method.

在我的代码中，我使用即时Trigger来安排Job:

In my code I schedule Jobs with an instant Trigger:

TriggerBuilder.newTrigger().startNow().build();

我的问题是如何知道哪些 Job 被安排到我的 Scheduler 中?目前只有一个 getCurrentlyExecutingJobs 方法似乎不可靠.

My question is how to tell which Jobs are scheduled into my Scheduler? There is only a getCurrentlyExecutingJobs method which seems unreliable so far.

推荐答案

下面的代码列出了与调度器 (Quartz 2.x.x) 关联的所有 Quartz 作业

The below code list all Quartz job associated to a scheduler (Quartz 2.x.x)

for (String groupName : scheduler.getJobGroupNames()) {

 for (JobKey jobKey : scheduler.getJobKeys(GroupMatcher.jobGroupEquals(groupName))) {

  String jobName = jobKey.getName();
  String jobGroup = jobKey.getGroup();

  //get job's trigger
  List<Trigger> triggers = (List<Trigger>) scheduler.getTriggersOfJob(jobKey);
  Date nextFireTime = triggers.get(0).getNextFireTime(); 

    System.out.println("[jobName] : " + jobName + " [groupName] : "
        + jobGroup + " - " + nextFireTime);

  }

}
