Getting batch job id nside ItemProcessListener in spring batch 5

Question

My listener is as given below :

@Component
@Slf4j
public class ProcessorExecutionListener implements ItemProcessListener<OriginDAO, DestinationDAO> {


    @Override
    public void onProcessError(OriginDAO originADAO, Exception e) {
        log.error("Want to display batch job id here in the logs. Is it possible?");
    }

}

I want to display batch job id in my logs on err. Any idea? ty.

Answer 1

You can do that by making the listener step-scoped and inject the step execution in it. Here is an example:

@Component
@StepScope
@Slf4j
public class ProcessorExecutionListener implements ItemProcessListener< OriginDAO, DestinationDAO> {

    @Value("#{stepExecution}")
    private StepExecution stepExecution;

    @Override
    public void onProcessError(OriginDAO item, Exception e) {
        Long jobId = stepExecution.getJobExecution().getJobId();
        log.error("batch job id = {}", jobId);
    }
    
}

This listener should be registered in the step as a listener as well.
