Question

类似的问题似乎已经被问过很多次了，但是我仍然找不到确切的答案。我使用org.quartz.StatefulJob来设置一个排定的作业，通过模拟Exception和Spring cron来重试5次。触发它，但发生了一些异常，详细信息如下：

@Service(value = "cronJobRetryImpl")
public class DuMiSynchronizationRetryRest implements StatefulJob {
    private Logger logger = Logger.getLogger(getClass());

    @Override
    public void execute(JobExecutionContext context) throws 
JobExecutionException {
        logger.info("enter execute ...");
        JobDataMap dataMap = context.getJobDetail().getJobDataMap();
        long count = 
            NumberUtils.toLong(String.valueOf(dataMap.get("count")));

        if (count >= 5) {
            logger.info("Retries exceeded...");
            JobExecutionException e = new JobExecutionException("Retries 
                exceeded");
            e.setUnscheduleAllTriggers(true);
            throw e;
        }

        try {
            logger.info("business begin...");
            dataMap.put("count", 0);
            int n = 10 / 0;
        } catch (Exception e) {
            count++;
            dataMap.putAsString("count", count);
            JobExecutionException e2 = new JobExecutionException(e);
            try {
                logger.info("Thread begin to sleep for 3 seconds...");
                Thread.sleep(3000);
            } catch (InterruptedException e1) {
                logger.info("interrupted exception",e1);
            }
            e2.refireImmediately();
            logger.info("job refired ...");
            throw e2;
        }

    }
}

这是Spring xml：

<!-- retry test start -->
<bean id="cronJobRetryImplTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" lazy-init="true">
    <property name="targetObject">
        <ref bean="cronJobRetryImpl" />
    </property>
    <property name="targetMethod">
        <value>execute</value>
    </property>
    <property name="concurrent" value="false" />
</bean>
<bean id="cronJobRetryTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail">
        <ref bean="cronJobRetryImplTask" />
    </property>
    <property name="cronExpression">
        <value>20 30 9 * * ?</value>
    </property>
</bean>
<!-- retry test end -->
<bean id="startQuertz" lazy-init="false" autowire="no"     
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
            <ref bean="cronJobRetryTime" />
        </list>
    </property>

我计划在每9:30:20 AM触发一次，结果是：

是的，是的，samabcde的重播是有效的，感谢samabcde的耐心和努力，但是代码本身似乎存在问题。我尝试运行这些代码，但是在发生模拟异常时无法再次执行该作业：

日志显示了一个异常，没有更多线索。我如何实现我的目标？

Answer 1

Spring Quartz BeanCreationException问题

从Spring xml

<bean id="cronJobRetryImplTask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" lazy-init="true">
    <property name="targetObject">
        <ref bean="cronJobRetryImpl" />
    </property>
    <property name="targetMethod">
        <value>execute</value>
    </property>
    <property name="concurrent" value="false" />
</bean>

未指定MethodInvoker（MethodInvokingJobDetailFactoryBean扩展）的参数，因此它假定没有参数。结果是例外

由以下原因引起：org.springframework.beans.factory.BeanCreationException：在类路径资源[applicationContext-job.xml]中定义名称为'cronJobRetryImplTask'的bean创建时出错：调用init方法失败；嵌套的异常是java.lang.NoSuchMethodException：tv.huan.cms.services.rest.DuMiSynchronizationRetryRest。 execute（）

抛出

，因为在execute类中没有方法DuMiSynchronizationRetryRest没有参数。

要解决此问题，请使用JobDetailFactoryBean代替Java Doc of MethodInvokingJobDetailFactoryBean

中所说的MethodInvokingJobDetailFactoryBean

避免了实现仅在Spring管理的目标bean上调用现有服务方法的单行Quartz Job 。

但是，DuMiSynchronizationRetryRest被实现为Quartz Job，并使用execute的Job方法JobExecutionContext。在这种情况下，JobDetailFactoryBean应该是适当的工厂bean。要更改工厂bean，只需将 cronJobRetryImplTask 的bean定义更新为

<bean id="cronJobRetryImplTask"
    class="org.springframework.scheduling.quartz.JobDetailFactoryBean"
    lazy-init="true">
    <property name="jobClass">
        <value>gov.housingauthority.pass.app.DuMiSynchronizationRetryRest
        </value>
    </property>
</bean>

由于更改了cronJobRetryImpl注释后不需要@Service bean 也可以删除。

最后，由于Java Doc of StatefulJob中的建议，StatefulJob已过时，

使用DisallowConcurrentExecution和/或PersistJobDataAfterExecution 注释。

作业不立即重试问题

对于作业不能立即重试的问题，这是由于使用 e2.refireImmediately();，这只是一个吸气剂。要设置重发射标志：

对于版本1.5.2或之前的石英，我们可以使用new JobExecutionException(e, true)，其中第二个参数会将refireImmediately设置为true。

在1.7.2版之后，提供了setter方法setRefireImmediately(boolean refireImmediately);。

无法在Spring cron中执行Quartz作业
