I am using Spring Batch and my step configuration is as below:
@Bean
public Step testStep(
JdbcCursorItemReader<TestStep> testStageDataReader,
TestStepProcessor testStepProcessor,
CompositeItemWriter<Writer> testWriter,
PlatformTransactionManager transactionManager,
JobRepository jobRepository) {
return stepBuilderFactory
.get("TESTING")
.<>chunk(100)
.reader(testStageDataReader)
.processor(testStepProcessor)
.writer(testWriter)
.transactionManager(transactionManager)
.repository(jobRepository)
.build();
}
And in my writer:
void write(List<? extends TestEntity> items) {
try {
testRepository.saveAll(items);
} catch (Exception exp) {
log.error("Exception while writing the batch", Exp);
//If there is an exception try individual items and skip filed ones
items.forEach(eachTask -> {
try {
testRepository.save(eachTask);
} catch (Exception exp) {
logException(exp, eachTask.getId());
}
});
}
With the code, I expected that if something goes wrong with the batch then I will try individual items and skip the failed ones.
However, it is not happening. Seems transaction is lost and Is not recovered.

The expectation is incorrect. Chunk scanning is triggered when a skippable exception is thrown from the item writer. This does not seem the case from your configuration: you did not configure any skippable exception and your writer does not throw one. Your step definition should be something like:
return stepBuilderFactory
.get("TESTING")
// other properties
.skip(MySkippableException.class)
.skipLimit(10)
.build()
And your writer should throw MySkippableException
at some point.
