Quartz Scheduler检查当前正在执行的作业

Question

我没有JobExecutionContext。如果我使用getCurrentlyExecutingJobs但不过滤getFireTime会怎样？就像下面的方法一样。

我正在寻找How to check whether Quartz cron job is running?的灵感。

    /**
     * 
     * @param jk JobKey
     * @return
     * @throws SchedulerException
     */
    public boolean isJobRunning(JobKey jk)
            throws SchedulerException {
        List<JobExecutionContext> currentJobs = this.getJobScheduler().getCurrentlyExecutingJobs();

        for (JobExecutionContext jobCtx : currentJobs) {
            String thisJobName = jobCtx.getJobDetail().getKey().getName();
            String thisGroupName = jobCtx.getJobDetail().getKey().getGroup();
            if (jk.getName().equalsIgnoreCase(thisJobName) && jk.getGroup().equalsIgnoreCase(thisGroupName)
                    //&& !jobCtx.getFireTime().equals(this.getJobScheduler().getContext().getFireTime())
                ) {
                return true;
            }
        }
        return false;
    }   
}
