I need to store Job ExecutionId as one of the fields of Entity. (I am using JpaItemWriter) One of topic here explains from StepExcecution, I can get StepContext -> JobExecution. In that case how to get StepExecution? (I have no need to pass any data from one step to another, all I need is JobExecuionId) Thanks for help, Muneer Ahmed We can set the scope as job using @Scope("job") of Itemprocessor and can easly get JobExecution using @Value("#{jobExecution}") expression as below. @Service @Scope("job") public class XsltTransformer implements ItemProcessor<Record, Record> { @Value("#

I am using Spring Batch and Partition to do parallel processing. Hibernate and Spring Data Jpa for db. For the partition step, the reader, processor and writer have stepscope and so I can inject partition key and range(from-to) to them. Now in processor, I have one synchronized method and expected this method to be ran once at time, but it is not the case. I set it to have 10 partitions , all 10 Item reader read the right partitioned range. The problem comes with item processor. Blow code has the same logic I use. public class accountProcessor implementes ItemProcessor{ @override public Custom

The issue is this: I have a Spring Batch job with a single step. This step is called multiple times. If every time it's called everything works ok (no Exceptions) the Job status is "COMPLETED". If something bad happends at least in one of the executions of the Step (an exception is thrown) I've configured a StepListener that changes the exit code to FAILED: public class SkipCheckingListener extends StepExecutionListenerSupport { public ExitStatus afterStep(StepExecution stepExecution) { String exitCode = stepExecution.getExitStatus().getExitCode(); if (stepExecution.getProcessorSkipCount() > 0

Whats the relationship/difference between Spring-Batch Reader 'pageSize' property and Writer 'commit-interval'. I may be wrong but I see a pattern in my application that for every pageSize exceeded I get see one commit being made. Is this true.? Thanks The commit-interval defines how many items are processed within a single chunk. That number of items are read, processed, then written within the scope of a single transaction (skip/retry semantics not withstanding). The page-size attribute on the paging ItemReader implementations ( JdbcPagingItemReader for example) defines how many records are

Could anybody help me figure out the solution to the following exception, I guess I just don't quite understand the Transaction Propagation mechanism, which hinder me from understanding the true meaning of the exception message shown below, so please, help me understanding the whole thing, thank you so much indeed! java.lang.IllegalStateException: Existing transaction detected in JobRepository. Please fix this and try again (e.g. remove @Transactional annotations from client). at org.springframework.batch.core.repository.support.AbstractJobRepositoryFactoryBean$1.invoke
