我在 jboss 4.0.5 上使用当前最新的quartz 1.8.3。
石英作业是持久的并保存到本地数据库中。
当我在执行的石英调度程序对象上调用 shutdown 或standby 方法时
作业仍然由调度程序继续执行,只是作业状态为空并且执行失败。
我希望(至少根据quartz API文档)当我关闭或使调度程序处于待机状态时,先前调度到数据库中的作业将不会被执行。
如果在调度程序上调用 shutdown 或standby 不是实现这一目标的方法,那么什么是呢?
这些作业不仅完成了执行,而且还继续触发计划的作业。
以下是所询问的附加信息:
public class QuartzNotificationsSchedulerBean implements NotificationsScheduler, ServletContextAware {
...
public String scheduleNotification(Notification notification) {
// Schedule the job with the trigger
try {
// Define job instance
String groupName = this.createNotificationGroupName(notification);
String triggerName = this.createNoficationTriggerName(notification);
String jobName = this.createNoficationJobName(notification);
JobDetail job = new JobDetail(jobName, groupName , ScheduledNotificationJob.class);
JobDataMap jobDataMap = new JobDataMap();
jobDataMap.putAll(notification.getContext());
job.setJobDataMap(jobDataMap);
Calendar notificationTime = notification.getTime();
Trigger trigger = new SimpleTrigger(triggerName, groupName , notificationTime.getTime());
scheduler.scheduleJob(job, trigger);
return trigger.getName();
} catch (SchedulerException e) {
throw new NotificationScheduleException(e, notification);
}
return null;
}
public void setServletContext(ServletContext servletContext) {
this.sf = (SchedulerFactory) servletContext.getAttribute(QuartzInitializerListener.QUARTZ_FACTORY_KEY);
try {
scheduler = sf.getScheduler();
if(scheduler.isStarted() == false) {
scheduler.start();
}
} catch (SchedulerException e) {
logger.error("Failed to load Quartz scheduler ", e);
}
}
}
以下是quartz配置属性的副本:

以下是 web.xml 中的一个片段,其中quartz 被初始化:
