我在Spring中使用Quartz Scheduler。 Quartz的版本是2.1.6,Spring的版本是3.1.3。
以下是配置:
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="autoStartup" value="true" />
<property name="applicationContextSchedulerContextKey" value="applicationContext" />
<property name="waitForJobsToCompleteOnShutdown" value="true" />
<property name="overwriteExistingJobs" value="true" />
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="quartzProperties">
<props>
<prop key="org.quartz.jobStore.driverDelegateClass">org.quartz.impl.jdbcjobstore.StdJDBCDelegate</prop>
</props>
</property>
<property name="triggers">
<list>
<ref bean="ldapSynchJob" />
</list>
</property>
</bean>
<bean id="ldapSynchJob" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="ldapSynch" />
<property name="cronExpression" value="0 45 0 * * ?" />
<property name="misfireInstructionName" value="MISFIRE_INSTRUCTION_FIRE_ONCE_NOW" />
</bean>
<bean id="ldapSynch" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<property name="jobClass" value="com.edfx.adb.ldap.scheduler.LDAPSynchronizer" />
</bean>
我希望如果服务器停止并重新启动,并且如果调度程序错过了一个作业,那么一旦服务器启动它就会执行错过的作业。所以我使用了持久存储,数据库。但它似乎无法正常工作。
当我第一次启动我的服务器时,我在数据库中看到,在qrtz_triggers表中,列NEXT_FIRE_TIME的值为1356808500000,这意味着Sun Dec 30 00:45:00 IST 2012.执行调度程序后,它更改为1356894900000,即Sun Dec 31 00:45:00 IST 2012.然后我停止了我的服务器并更改了系统时间并将系统时间设置为12月31日12:47 AM。然后我再次启动我的服务器。我期待一旦服务器启动它就会在错过工作时执行调度程序。但是NEXT_FIRE_TIME值改为1356981300000而不是解雇作业,即IST 2013年1月1日00:45:00。
显然这不是我们想要的,我无法找到为什么会发生这种情况。任何建议都对我很有帮助。
我使用的SessionFactory
为org.springframework.orm.hibernate4.LocalSessionFactoryBean
,hibernate.hbm2ddl.auto
已设为update
。
这是扩展QuartzJobBean
public class LDAPSynchronizer extends QuartzJobBean {
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
List<Attributes> currentUsersAttributes = LDAPManager.getManager().getCurrentUsersAttributes();
List<Attributes> pastUsersAttributes = LDAPManager.getManager().getPastUsersAttributes();
getLDAPSynchService(context).synchronizeUser(currentUsersAttributes, pastUsersAttributes);
}
private ILDAPSynchService getLDAPSynchService(JobExecutionContext context) {
ApplicationContext applicationContext = null;
try {
applicationContext = (ApplicationContext) context.getScheduler().getContext().get("applicationContext");
} catch (Exception e) {
}
if(applicationContext == null) {
applicationContext = ContextLoader.getCurrentWebApplicationContext();
}
return (ILDAPSynchService) applicationContext.getBean("ldapSynchService");
}
}
每次服务器在控制台中启动时,我都会收到此日志:

之后我看到QUARTZ_TRIGGERS`表的PREV_FIRE_TIME
设置为-1。并且行数永远不会超过1.我不知道它是否正常。
答案 0 :(得分:1)
经过两天的学习和搜索网,最后我能够解决问题。这是正确的代码:
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="autoStartup" value="true" />
<property name="applicationContextSchedulerContextKey" value="applicationContext" />
<property name="waitForJobsToCompleteOnShutdown" value="true" />
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="quartzProperties">
<props>
<prop key="org.quartz.jobStore.driverDelegateClass">org.quartz.impl.jdbcjobstore.StdJDBCDelegate</prop>
</props>
</property>
<property name="triggers">
<list>
<ref bean="ldapSynchJob" />
</list>
</property>
</bean>
<bean id="ldapSynchJob" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
<property name="jobDetail" ref="ldapSynch" />
<property name="misfireInstructionName" value="MISFIRE_INSTRUCTION_FIRE_ONCE_NOW" />
<property name="cronExpression" value="0 17 12 * * ?" />
</bean>
<bean id="ldapSynch" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<property name="jobClass" value="com.edfx.adb.ldap.scheduler.LDAPSynchronizer" />
</bean>
<property name="overwriteExistingJobs" value="true" />
导致了这个问题。它覆盖了NEXT_FIRE_TIME
表的QRTZ_TRIGGERS
值。
