问题
I have a Spring job that reads data from a flat file resource. When the job can't find the resource file (it works with a quartz) it throws an ItemStreamException that causes the job overfills my app's log.
org.springframework.batch.core.step.AbstractStep: Encountered an error executing the step
org.springframework.batch.item.ItemStreamException: Failed to initialize the reader

I just want to catch this runtime exception and produce a reduced log message without stacktrace but I can't figure out how to do it. I've tried it by defining some CustomItemReadListener and CustomErrorSkipListener. But I'm stuck.
This is a part of my job.xml file
<job id="readJob" xmlns="http://www.springframework.org/schema/batch" job-repository="jobRepository" restartable="false">
<!-- Steps -->
<step id="readStep" next="renameAndMoveFileSourceStep">
<tasklet transaction-manager="transactionManager">
<chunk reader="itemReader" processor="itemProcessor" writer="itemWriter" commit-interval="250" skip-limit="100000">
<skippable-exception-classes>
<include class="java.lang.Exception"/>
</skippable-exception-classes>
</chunk>
<listeners>
<listener ref="customErrorSkipListener"/>
<listener ref="customReadListener"/>
<listener ref="customStepListener"/>
</listeners>
</tasklet>
</step>
<step id="renameAndMoveFileSourceStep">
<tasklet ref="moveAndRenameTasklet"/>
</step>
<listeners>
<listener ref="jobListener"/>
</listeners>
</job>
I'd appreciate your help!
回答1:
What about a JobExecutionDecider which checks for file presence and let it decide to log reduced (custom) error message or go ahead for readStep step?
IMO is a more clear solution and show you the real job flow without hide it behind exception management.
回答2:
If you don't care about is resource not present then just set strict mode off for reader then it will not throw exception.
