Running a batch

[Jay Abrahm]

I have got another thread running but I think thats got too much data Forum link

I was trying to run the example in the Spring batch documentation but I can't seem to autowire the right classes. Couldn't correlate it to any sample in the spring samples also. Could someone guide me.

@Autowired
org.springframework.batch.core.launch.JobLauncher jobLauncher;

@Autowired
org.springframework.batch.core.repository.JobRepository jobRepository;

@Autowired
org.springframework.batch.core.Job job;

JobParameters jobParameters = new JobParameters();
JobExecution firstExecution = jobRepository.createJobExecution(job.getName(),jobParameters);
jobRepository.saveOrUpdate(firstExecution);
try {
	jobRepository.createJobExecution(job, jobParameters);
	fail();
} catch (JobRestartException e) {
	// expected
}

My configuration

<bean id="jobRepository"
	class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
	<property name="isolationLevelForCreate" value="ISOLATION_DEFAULT" />
	<property name="dataSource" ref="dataSource" />
	<property name="transactionManager" ref="transactionManager" />
</bean>


<bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
	<property name="jobRepository" ref="jobRepository" />
	<property name="taskExecutor">
		<bean class="org.springframework.core.task.SimpleAsyncTaskExecutor" />
	</property>
</bean>	

<job id="ordinaryJob" restartable="false">
	<step id="step1">
		<tasklet>
			<chunk reader="reader" writer="writer" commit-interval="3"/>
		</tasklet>
	</step>
</job>	


<!-- From the Spring samples -->
<bean id="reader" class="com.jci.hrob.batch.InfiniteLoopReader" />
<bean id="writer" class="com.jci.hrob.batch.InfiniteLoopWriter" />

Is that the actual code, or are you missing method name?

Thanks

Just the method name ;-) I thought it was insignificant. Was trying to make it as readable as possible. I even got the package names in.

This is straight out of the Spring documentation. Haven't changed anything. All three methods seem to be syntactically wrong.
createJobExecution
saveOrUpdate
createJobExecution

Got some success kick-starting the batch with quartz.SchedulerFactoryBean so was trying my luck with that but please do let me know if you can find something amiss here.

And Mark, you had mentioned in the previous post that the Spring Batch documentation it good. I woudln't disagree but a quick-start guide or a 3-step guide (whatever) would have helped.

Ok its not clear what the problem you facing is - but if your trying to run the job then the commandLineJobRunner does all the hardwork,

bash$ java CommandLineJobRunner endOfDayJob.xml endOfDay schedule.date(date)=2007/05/05

If your just tetsing (Say Junit) the @SpringRunner all with JobLauncherTestUtils takes care of all the plumbing code.
End To End Testing

In all the Batch Jobs I have written I never reference JobRepository - There enough help to do all the plumbing!

As for a 3-4 page guide to Spring Batch - I agree its a good idea. So why don't you start one? You already seem to have a 'nice' start up guide post here where you kind of gone through the steps!
I do suggest giving the whole Spring Batch documentation a read, it does cover everything.
