Question

我在使用主题中的配置实现故障转移时遇到问题。我有一个在石英（2.1.7）集群中配置的弹簧批处理作业。在配置文件中，我设置了requestsRecovery = true，我的石英配置文件是：

org.quartz.scheduler.instanceId=AUTO 
org.quartz.scheduler.instanceName = quartzScheduler 
org.quartz.scheduler.rmi.export = false 
org.quartz.scheduler.rmi.proxy = false 
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool 
org.quartz.threadPool.threadCount = 10 
org.quartz.threadPool.threadPriority = 5 
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true 

org.quartz.jobStore.useProperties=true 
org.quartz.jobStore.isClustered = true 

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX 

org.quartz.jobStore.tablePrefix = QRPC_ 

org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate 
org.quartz.scheduler.jmx.export=true 
org.quartz.jobStore.clusterCheckinInterval = 20000

我的弹簧配置如下：

<context:component-scan base-package="it.myproject.scheduler" /> 

<bean name="myJob" class="it.myproject.scheduler.CustomJobDetailFactoryBean"> 
    <property name="jobClass" value="it.myproject.scheduler.SellJob" /> 
    <property name="requestsRecovery" value="true" /> 
    <property name="durability" value="true"/> 
</bean> 

<bean id="cronTrigger" class="it.myproject.scheduler.CustomCronTriggerFactoryBean"> 
    <property name="jobDetail" ref="myJob"/> 
    <property name="cronExpression" value="${sched.expression}"/> 
</bean> 

<bean id="quartzScheduler" 
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 
    <property name="jobDetails"> 
        <list> 
            <ref bean="myJob" /> 
        </list> 
    </property> 
    <property name="triggers"> 
        <list> 
            <ref bean="cronTrigger" /> 
        </list> 
    </property> 
    <property name="dataSource" ref="myDataSource" /> 
    <property name="transactionManager" ref="transactionManager" /> 
    <property name="schedulerName" value="quartzScheduler"/> 
    <property name="configLocation" value="file:///quartz.properties" /> 
    <property name="applicationContextSchedulerContextKey" value="applicationContext" /> 
    <property name="overwriteExistingJobs" value="true"/> 
    <property name="autoStartup" value="true" /> 
    <property name="jobFactory"> 
        <bean class="it.myproject.scheduler.AutowiringSpringBeanJobFactory"/> 
    </property> 
</bean>

工作代码：

import org.springframework.scheduling.quartz.CronTriggerFactoryBean; 
import org.springframework.scheduling.quartz.JobDetailAwareTrigger; 

public class CustomCronTriggerFactoryBean extends CronTriggerFactoryBean { 

    @Override 
    public void afterPropertiesSet() { 
        super.afterPropertiesSet(); 
        // Remove the JobDetail element 
        getJobDataMap().remove(JobDetailAwareTrigger.JOB_DETAIL_KEY); 
    } 
} 

public class CustomJobDetailFactoryBean extends JobDetailFactoryBean { 
    private boolean requestsRecovery; 

    public CustomJobDetailFactoryBean() { 
        super(); 
    } 

    @Override 
    public void afterPropertiesSet() { 
        super.afterPropertiesSet(); 
        JobDetailImpl jobDetail = (JobDetailImpl) getObject(); 
        jobDetail.setRequestsRecovery(isRequestsRecovery()); 
    } 

    public boolean isRequestsRecovery() { 
        return requestsRecovery; 
    } 

    public void setRequestsRecovery(boolean requestsRecovery) { 
        this.requestsRecovery = requestsRecovery; 
    } 
} 

public class myJob extends QuartzJobBean {
    @Autowired 
    private MyScheduler task; 

    @Override 
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException { 
        task.runJob(); 
    } 
}

我已经在tomcat上的2个独立机器中部署了我的应用程序。并发工作正常，当我启动服务器时，只有1个实例获取锁并且正常工作，但如果我停止已获得锁的机器，则第二台机器不会进行故障转移。如果我只使用一台服务器，则会观察到相同的结果，停止此操作并重新启动不会进行故障转移。在表job detail中，requests_recovery列设置为1.有人可以帮我吗？

我有同样的问题。我正在做的是，在实例启动时擦除表。特别是，具有自动生成的实例ID的表。但是必须有其他解决方案。

使用spring配置石英故障转移
