Configuring Spring Batch Unexpected Error Conditions

[mchenryed]

I was wondering if there was a way to have Spring Batch do the following:

Say I have 3 steps A, B and C and I have a file clean up task on Step D.

I process step A, and start on B and I get a totally unexpected exception -- say a null pointer exception or class cast exception -- something totally unexpected.

I want to completely stop task B (or A or C) and go to my file clean up task on Step D and then complete my job.

Thanks

For what it is worth, I seemed to have figured it out. For future reference (I didn't find many crystal clear examples out on the web) here is what I did:

On each step's afterStep method, I added the following:

if ( stepExecution.getStatus().equals(BatchStatus.FAILE D)) {
logTheError(stepExecution.getExitStatus().getExitD escription());
stepExecution.setStatus(BatchStatus.COMPLETED);
exitStatus = new ExitStatus("CLEANUP", "Cleanup");
}

Then in my spring xml configuration I did the following for each step:

<batch:step id="CSVA">
<batch:tasklet transaction-manager="transactionManager">
<batch:chunk reader="CSVAReader" processor="CSVAProcessor" writer="CSVAWriter" commit-interval="1"/>
</batch:tasklet>
<batch:next on="CLEANUP" to="FileCleanup"/>
<batch:next on="*" to="CSVB"/>
</batch:step>

If anyone sees any problems with that, please let me know, but it appears to work.
