仕事のスケジュールにクォーツスケジューラを使用しています。CronTrigger を使用しました。しかし問題は、トリガーが複数回起動されることです。これがcronスケジューラをセットアップするための私のコードです..

SchedulerFactory schFactory = new StdSchedulerFactory();
        Scheduler sched = null;
        CronTrigger cronTrigger = null;
        try {
            sched = schFactory.getScheduler();
            JobDetail jobDetail = new JobDetail("job1", "group1",SchedulerPBGC.class);

            String cronTimerStr = "* 16 15 * * ? *";

            LOG.warn("CRON TRIGGER FORMAT  FOR PROCESSING PB GC DATA:"+cronTimerStr);

            cronTrigger = new CronTrigger("SchedTrigger", "Group1", cronTimerStr);


            sched.scheduleJob(jobDetail, cronTrigger);          
            sched.start();

            LOG.warn("SCHEDULER REGISTERED FOR PROCESSING PB GC DATA :  TIME :"+cronTimerStr);          

        } catch (SchedulerException se) {
            LOG.error("SchedulerException Message::"+se.getLocalizedMessage());     
        }

ここで私のスケジューラーはジョブを 10 回実行します...ここでログを見ることができます..

CronTimer イテレータを 1 に設定するにはどうすればよいですか? またはスケジューラを停止してジョブを複数回実行するにはどうすればよいですか。

なにか提案を ？ありがとう、グンジャン・シャー。

私は解決策を得ました..

私が使用した cron 構文は次のとおりです。 String cronTimerStr = "* 16 15 * * ? *";

ここで 15:16 の時間に、Quartz はすべての可能なワーカーを毎秒初期化します。したがって、その 1 分 (@ 16 分 60 秒) 以内に、最大 60 のスレッドを初期化するとします。

2 番目のパラメーターをゼロに設定しました。したがって、新しい構文は「0 16 15 * * ? *」です。

今では正常に動作します。

ありがとう、グンジャン・シャー。
