问题描述
我正在尝试使用 Spring Batch &石英在一个项目中.目标是使用 Quartz 安排 spring-batch 作业.我有以下豆子 -
I am trying to use spring batch & quartz in a project. The objective is to schedule a spring-batch job using Quartz. I have the following beans -
bean id="updateDataFeedJob" class="package.UpdateDataFeedJob" />
<bean id="UpdaterOnScheduleJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="updateDataFeedJob"/>
<!-- the method to call inside of com.siemens.scr.schedule.UpdateDataFeedJob -->
<property name="targetMethod" value="execute"/>
</bean>
<bean id="cronTriggerId" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="UpdaterOnScheduleJobDetail" />
<!-- run every morning at 3AM -->
<!-- <property name="cronExpression" value="0 0 3 * * ?" /> -->
<!-- Fires every five minutes -->
<property name="cronExpression" value="0 0/5 * * * ?" />
</bean>
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="cronTriggerId" />
</list>
</property>
</bean>
UpdateDataFeedJob 是 -
The UpdateDataFeedJob is -
public class UpdateDataFeedJob {
public void execute() throws Exception {
System.out.println("Hello World. Running the job");
CommandLineJobRunner.main(new String[]{"GetFleetUpdatesJob.xml", "getFleetUpdatesJob"});
}
}
样本调用是 -
public class Client {
public static void main(String[] args){
//CommandLineJobRunner.main(new String[]{"GetFleetUpdatesJob.xml", "getFleetUpdatesJob"});
new ClassPathXmlApplicationContext("GetFleetUpdatesJob.xml");
}
}
我不断收到以下异常 -
I keep getting the following exception -
ERROR - Job Terminated in error: A job execution for this job is already running: JobInstance: id=0, JobParameters=[{}], Job=[getFleetUpdatesJob]
org.springframework.batch.core.repository.JobExecutionAlreadyRunningException: A job execution for this job is already running: JobInstance: id=0, JobParameters=[{}], Job=[getFleetUpdatesJob]

推荐答案
我成功了.我不知道确切的原因 &如果有人可以发表评论将不胜感激 -
I got this working. I am not aware of the exact reason & will appreciate if someone can comment -
我在 applicationContext.xml
<bean id="transactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager"/>
现在我没有得到那个例外 &石英能够调用弹簧批处理作业
Now i dont get that exception & quartz is able to call the spring batch job
