Question:

I want to be able to stop a job when a timing threshold is met. There are 2 approaches I was thinking about. First was to stop the job in the afterStep. However, I do not want it to have a Stopped status if it is at the completion of the last step. Therefore, I am going with stopping it in the beforeStep. I tried experimenting with

public void beforeStep(StepExecution stepExecution) { stepExecution.setStatus(BatchStatus.STOPPED); return; }

and

public void beforeStep(StepExecution stepExecution) { stepExecution.setExitStatus(ExitStatus.STOPPED); return; }

Neither of these worked. Any suggestions?

The problem with the above code is that stops the currently running step, not the entire job. Perhaps if you add and adjust the following code in the job-current-step configuration will terminate the job when the ExitStatus of the step is STOPPED and when runned again the job will start from the next step.<br />(Taken from <a href="http://docs.spring.io/spring-batch/reference/html/configureStep.html#configuringForStop" rel="nofollow">here</a>)

<step id="step1" parent="s1"> <stop on="STOPPED" restart="step2"/> </step>

<br /><a href="http://docs.spring.io/spring-batch/reference/html/configureStep.html#batchStatusVsExitStatus" rel="nofollow">This</a> might also help solve the confusion between ExitStatus/BatchStatus.

About the timing threshold... As I understand so far you plan to measure time of the <strong>current step only</strong> (beforestep - afterstep), no matter how long previous steps were running. To calculate and the previous steps try adding a timestamp in JobParameters and check when that threshold is passed.

In my case a needed to stop job from afterStep. So I returned ExitStatus.Unknown and catch from job like that:

step().on("UNKNOWN").end()

So the job finish without error and I can restart the entire job when i want, whitout "restartable" option.

Hope this can help you.

i suggest looking at <a href="http://docs.spring.io/spring-batch/reference/html/repeat.html#completionPolicies" rel="nofollow">CompletionPolicies</a> especially the <a href="http://docs.spring.io/spring-batch/apidocs/org/springframework/batch/repeat/policy/TimeoutTerminationPolicy.html" rel="nofollow">TimeoutTerminationPolicy</a>

You can set a timer (or something similar) and when receive time-limit notitication stop the job as described in <a href="http://docs.spring.io/spring-batch/reference/html-single/index.html#stoppingAJob" rel="nofollow">Stopping a job</a>.<br /> If you want the job is completed normally even if a time-alarm were broadcasted during last step, you can do check (using <a href="http://docs.spring.io/spring-batch/reference/html-single/index.html#JobOperator" rel="nofollow">JobOperator</a>) to query job progress.
