在弹簧关闭时从DB中移除石英触发器

我目前使用下面的配置在spring下运行Quartz。使用数据库作为调度程序后端的原因是启用集群模式。

这一切都运行正常,但如果我想删除InitialAbstractPublicationJob我有问题。让我们说删除下面的所有配置,除了调度程序本身。 DB表QRTZ_TRIGGERS中仍存在一行。

  TRIGGER_NAME: initialAbstractTrigger
 TRIGGER_GROUP: DEFAULT
      JOB_NAME: initialAbstractDataAccessDelegator
     JOB_GROUP: DEFAULT
   IS_VOLATILE: 0
   DESCRIPTION: NULL
NEXT_FIRE_TIME: 1330953433511
PREV_FIRE_TIME: 1330953432511
 TRIGGER_STATE: WAITING
  TRIGGER_TYPE: SIMPLE
    START_TIME: 1330953336511
      END_TIME: 0
 CALENDAR_NAME: NULL
 MISFIRE_INSTR: 0
      JOB_DATA: NULL
1 row in set (0.00 sec)

这一行导致quartz尝试加载SpringPublicationJobBean,它在Spring中不再存在,并且异常比比皆是。所以我的问题是:是否可以配置调度程序在关闭或启动spring时从数据库刷新触发器,并从spring applicationContext.xml重新创建触发器

<bean id="initialAbstractPublicationJob" class="bbc.forge.ibroadcast.snowball.InitialAbstractPublicationJob" />
<bean id="initialAbstractDataAccessDelegator" class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass" value="bbc.forge.ibroadcast.snowball.DelegatingJobBean"/>
    <property name="durability" value="false" />
    <property name="jobDataAsMap">
        <map>
            <entry key="job.bean.name" value="initialAbstractPublicationJob" >
            </entry>
            <entry key="sdtl.file.prefix" value="sdtl_" >
            </entry>
        </map>
    </property>
</bean>
<bean id="initialAbstractTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
     see the example of method invoking job above 
    <property name="jobDetail" ref="initialAbstractDataAccessDelegator" />
     10 seconds 
    <property name="startDelay" value="0" />
     repeat every n milliseconds 
    <property name="repeatInterval" value="1000" />
</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="initialAbstractTrigger" />
        </list>
    </property>
    <property name="dataSource">
        <ref bean="dataSource" />
    </property>
    <property name="applicationContextSchedulerContextKey">
        <value>applicationContext</value>
    </property>
    <property name="quartzProperties">
        <props>
            <prop key="org.quartz.jobStore.isClustered">true</prop>
            <prop key="org.quartz.scheduler.instanceId">AUTO</prop>


        </props>
    </property>

</bean>

您可以使用XMLSchedulingDataProcessorPlugin在单独的XML文件中存储作业并触发配置。此文件可以在启动时覆盖现有作业

<?xml version="1.0" encoding="UTF-8"?>
<job-scheduling-data xmlns="http://www.quartz-scheduler.org/xml/JobSchedulingData"
                     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                     xsi:schemaLocation=" http://www.quartz-scheduler.org/xml/JobSchedulingData http://www.quartz-scheduler.org/xml/job_scheduling_data_2_0.xsd ">

    <processing-directives>
        <overwrite-existing-data>true</overwrite-existing-data>
        <ignore-duplicates>true</ignore-duplicates>
    </processing-directives>

</job-scheduling-data>

重复的问题:delete-trigger-in-quartz

如果你想在春季关机时更新触发器,只需在@PreDestroy方法中执行这些操作。
