How do I get Spring Batch Job ContextId in ItemProcessor or ItemWriter?

Question

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.

Answer 1

I had a similar issue when I wanted to get the JobInstanceID. Below is how I got StepExecution and then retreived JobExecution. I hope this helps.

public class FoobarItemProcessor implements ItemProcessor {

private JobExecution jobExecution;

@BeforeStep
public void beforeStep(StepExecution stepExecution) {
    jobExecution = stepExecution.getJobExecution();
}
