Spring Batch: How retrieve the skipped exceptions for Testing purposes - spring-batch

Question

I am working with Spring Batch 3.0.7.RELEASE version
About Skip I have the following:
<batch:chunk reader="personErrorSkipFileItemReader"
processor="personErrorSkipItemProcessor"
writer="personErrorSkipFileItemWriter"
commit-interval="100"
skip-limit="11">
<batch:skippable-exception-classes>
<batch:include class="org.springframework.batch.item.file.FlatFileParseException"/>
<batch:include class="com.manuel.jordan.batch.exception.PersonBatchException"/>
</batch:skippable-exception-classes>
</batch:chunk>
It works how is expected.
For logging and test purposes I need retrieve the following data:
skipped elements (for example 8 of 11) showing the amount such as:
By FlatFileParseException 5
By PersonBatchException 3
Even better if can show in what step and area (reader, processor, writer) was thrown each skipped item.
Working through JobExecution, I have the following
List<Throwable> exceptions = jobExecution.getAllFailureExceptions();
logger.info("exceptions size: {}", exceptions.size());
for(Throwable throwable : exceptions){
logger.error("Throwable Class: {}", throwable.getClass().getSimpleName());
logger.error("{}", throwable.getMessage());
}
List<Throwable> exceptions_ = jobExecution.getFailureExceptions();
logger.info("exceptions_ size: {}", exceptions_.size());
for(Throwable throwable : exceptions_){
logger.error("Throwable Class: {}", throwable.getClass().getSimpleName());
logger.error("{}", throwable.getMessage());
}
But the size of both collections are higher than 1 and show the exceptions just when the Job completes how FAILED.
Because 8 < 11, the Job completes how COMPLETED and the lists sizes returns 0.

Answer 1

implement SkipListener , It has three callback methods
1 :onSkipInProcess
2 :onSkipInWrite
3: onSkipInRead
