spring batch| Graceful job termination within the job

Question

After launching a job, in the before job - there are certain occasions where we want to gracefully terminate the job (i.e. dont run the job at all but neither complain i.e .no exception). The current way of doing this looks like invoking jobExecution.stop - However, this results in JobInteruptedException which further results in logger.error invocation.

Is there any other better programmatic alternative (without manual intervention)?

Answer 1

You may read :

• Section 5.3.3 Configuring for Stop and
• section 5.3.4. Programmatic Flow Decisions.

Just introduce an end element for your first step based on condition:

The 'end' element instructs a Job to stop with a BatchStatus of COMPLETED.

Answer 2

I solved the problem adding a flag boolean executeTheJob in my "before job" listener that I set to false when I don't want to execute the job.

Then I handle that in my firstStep with this configuration:

<step id="firstStep" >
    <tasklet ref="myFirstTasklet"/>
    <stop on="STOPPED" restart="firstStep" />
    <next on="COMPLETED" to="nextStep"/>
</step>

And at the beginning of my first tasklet I have this:

if (executeTheJob == false) {
    contribution.setExitStatus(ExitStatus.STOPPED);
}
