在石英調度程序中多次調用作業

[英]Job is getting called multiple times in quartz scheduler

 原文  2015-02-06 06:30:23  4   2    java/ spring/ spring-mvc/ quartz-scheduler/ spring-batch

問題描述

我正在使用石英調度程序和cron表達式運行批處理作業，但是該作業在一個循環中被多次調用。

這是配置 

public static void main(String[] args) {            
        String[] springConfig  = 
            {   
                "classpath:/execs/execJob.xml" 
            };

        ApplicationContext context = new ClassPathXmlApplicationContext(springConfig);       

}

在execJob.xml- 

<import resource="classpath:/schedulers/BatchLaunch.xml" />

在BatchLaunch.xml中 

<import resource="classpath:/environment/springBatchDbContext.xml" />
<import resource="classpath:/environment/simpleJobEnvironment.xml" />

<import resource="classpath:/jobs/Job.xml" />


<bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" >
    <property name="triggers">

            <ref bean="JobTrigger" />

    </property>
    <property name="jobFactory">
        <bean class="org.springframework.scheduling.quartz.SpringBeanJobFactory" />
    </property>
    <property name="schedulerContextAsMap">
        <map>
            <entry key="job" value-ref="job" />
            <entry key="jobLauncher" value-ref="jobLauncher"/>
            <entry key="jobLocator" value-ref="jobRegistry"/>
        </map>
    </property>
</bean>

 <bean id="JobTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="JobDetail" />
    <property name="cronExpression" value="JobSchedule!{receive.recon.file.schedule}" />
</bean>



  <bean id="JobDetail" class="org.springframework.scheduling.quartz.JobDetailBean">
    <property name="jobClass" value="com.abc.scheduler.JobLauncherDetails" />
     <property name="group" value="quartz-batch" />
    <property name="jobDataAsMap">
        <map>
            <entry key="jobName" value="Job"/>
             <entry key="reconTimestamp" value="JobSchedule!{receive.recon.file.schedule.timestamp}"/>

        </map>
    </property>
</bean>




<bean id="quartzPlaceholderProperties"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="ignoreUnresolvablePlaceholders" value="true" />
    <property name="location" value="classpath:reconCronSchedule.properties" />
    <property name="placeholderPrefix" value="JobSchedule!{" />
    <property name="placeholderSuffix" value="}" />
</bean>

這是cron 

receive.recon.file.schedule=* */10 * * * ?
receive.recon.file.schedule.timestamp=2014-03-01 00:00:00

在這里，反復調用小任務。 有人可以建議這里發生了什么嗎？ 我缺少任何配置或做錯了什么嗎？

2 個解決方案

解決方案1
 3 已采納  2015-02-06 12:40:29

哎呀！ 我當時在做愚蠢的事情。 一切都在cron表達式中，我每秒都在計划它。

解決方案2

我們遇到了這個問題。 我們的情況是我們在applicationContext.xml中配置了一個bean，但我們也使用了： 

ApplicationContext context = new ClassPathXmlApplicationContext("/config/applicationContext.xml");

因此，總共有兩個bean。所以我們的任務執行兩次。 最近，我們對此進行了更改： 

MyBean myBean = (MyBean) BeanUtils.getBean("beanName", MyBean.class);

一切都好。

這是BeanUtils： 

public final class BeanUtils implements ApplicationContextAware {

private static ApplicationContext applicationContext;

public static Object getBean(String beanName) {
    return applicationContext.getBean(beanName);
}

public static <T> T getBean(String beanName, Class<T> clazs) {
    return clazs.cast(getBean(beanName));
}

public void setApplicationContext(ApplicationContext applicationContext)
        throws BeansException {
    BeanUtils.applicationContext = applicationContext;
}

public static ApplicationContext getApplicationContext() {
    return applicationContext;
}

}

希望這可以幫助。
