Quartz如何实现判断某个任务是否正在运行--SpringCloud工作笔记181

1.通过代码动态获取所有的任务,然后获取任务来判断,这种方法,在集群环境下是不好使的,

因为获取到的任务都是某个实例上的任务:

public static boolean isJobRunning(JobExecutionContext ctx, String jobName, String groupName)
        throws SchedulerException {
    List<JobExecutionContext> currentJobs = ctx.getScheduler().getCurrentlyExecutingJobs();
 
    for (JobExecutionContext jobCtx : currentJobs) {
        String thisJobName = jobCtx.getJobDetail().getKey().getName();
        String thisGroupName = jobCtx.getJobDetail().getKey().getGroup();
        if (jobName.equalsIgnoreCase(thisJobName) && groupName.equalsIgnoreCase(thisGroupName)
                && !jobCtx.getFireTime().equals(ctx.getFireTime())) {
            return true;
        }
    }
    return false;
}

//1.这里你还可以使用factory获取scheduler,如果没有groupName的话,只用jobName这一个参数就可以了.

2.判断某个定时任务是否是暂停的状态.

private Boolean isJobPaused(String jobName) throws SchedulerException {
 
    JobKey jobKey = ne
