Quartz Scheduler在关机后没有停止

Question

我在jboss 4.0.5上使用目前最新的石英1.8.3.quartz作业是持久的并保存到本地数据库中.当我在执行石英调度程序对象上调用shutdown或standby方法时,调度程序仍继续执行作业,只有作业状态为空且执行失败.

我希望(至少根据石英API文档)当我关闭或使调度程序处于待机状态时,之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不是实现它的方法,那是什么？

这些工作不只是完成执行,而是继续触发计划工作.

以下是其他信息:

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:

#============================================================================
# Configure Main Scheduler Properties  
#============================================================================

org.quartz.scheduler.instanceName = scheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.wrapJobExecutionInUserTransaction = true

#============================================================================
# Configure ThreadPool  
#============================================================================

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 45
org.quartz.threadPool.threadPriority = 5

#============================================================================
# Configure JobStore  
#============================================================================

org.quartz.jobStore.misfireThreshold = 60000
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#org.quartz.jobStore.useProperties = false
org.quartz.jobStore.dataSource = FOR_QUARTZ
org.quartz.jobStore.isClustered = true
org.quartz.jobStore.clusterCheckinInterval = 20000


#============================================================================
# Configure Datasources  
#============================================================================

org.quartz.dataSource.FOR_QUARTZ.jndiURL = java:jdbc/live-quartz

这是一个来自web.xml的片段,其中初始化了quartz:

 <!--  START NOTIFICATION SERVICE -->
    <context-param>
        <param-name>config-file</param-name>
        <param-value>wm_quartz.properties</param-value>
    </context-param>
    <context-param>
        <param-name>shutdown-on-unload</param-name>
        <param-value>true</param-value>
    </context-param>
    <context-param>
        <param-name>start-scheduler-on-load</param-name>
        <param-value>true</param-value>
    </context-param>    

    <listener>
        <listener-class>org.quartz.ee.servlet.QuartzInitializerListener</listener-class>
    </listener> 

谢谢

Answer 1

如果在调用shutdown时有任何作业正在执行,是否中断这些作业取决于属性org.quartz.scheduler.interruptJobsOnShutdown.

请参阅http://jira.terracotta.org/jira/browse/QTZ-41?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel.我无法找到更多关于此的文档.

另一个属性是org.quartz.scheduler.makeSchedulerThreadDaemon=true,一旦调用线程关闭,它将关闭quartz调度程序.我不知道工作状况会发生什么.

如评论中所述,发布一些代码和配置以获得明确的答案.

Answer 2

请尝试在初始化调度程序时应用这些配置

org.quartz.threadPool.makeThreadsDaemons=true
org.quartz.scheduler.makeSchedulerThreadDaemon=true
org.quartz.scheduler.interruptJobsOnShutdown=true
org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true
