初めてジョブを保存し、以下のコードでcrontriggerを使用してスケジュールしました。
package com.generalsentiment.test.quartz;

System.out.println("------- Initializing -------------------");

.withSchedule(cronSchedule("00 15 15 * *

Date ft = sched.scheduleJob(job, trigger);
System.out.println(sched.getSchedulerName());
System.out.println(job.getKey() + " has been scheduled to run at: " + ft
+ " and repeat based on expression: "
+ trigger.getCronExpression());
System.out.println("------- Starting Scheduler ----------------");
/*

*/
sched.start();
System.out.println("------- Started Scheduler -----------------");
System.out.println("------- Waiting five minutes... ------------");
try {
// wait five minutes to show jobs
Thread.sleep(300L * 1000L);

SchedulerMetaData metaData = sched.getMetaData();
System.out.println("Executed " + metaData.getNumberOfJobsExecuted() + " jobs.");
}
public static void main(String[] args) throws Exception {
CronTriggerExample example = new CronTriggerExample();
example.run();
}
}
そして、詳細はテーブルに保存されます- QRTZ_CRON_TRIGGERS
、QRTZ_JOB_DETAILS
&QRTZ_TRIGGERS
私の疑問は、DBに保存されているジョブをどのようにスケジュールするかです。jspページにジョブのリストを表示する方法とそれらを自動的にトリガーする方法。私たちのものは、Hibernate3ORMを使用したstruts2アプリケーションです。アプリケーションのロード時にクォーツスケジューラを初期化しようとしています。しかし、できません。
