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

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 {

@Value("#{jobExecution}")
private JobExecution jobExecution;

}
