Add parameter to job context from tasklet step and use in later steps in Spring Batch

Question

For now, I\'m using jobParameters to get the filenames for both my FlatFileItemReader and FlatFileItemWriter. It\'s okay for testing my batch, but my goal is to read a file in s

Answer 1

In tasklet you have ChunkContext at your disposal so you do not need @BeforeStep, you can remove it (in my configuration it is not invoked at all, and when you think of it as one action step does not make much sense but I do not see NPE so guess that part work). We solved it with one of two approaches:

1. You can put any parameter from tasklet to job ExecutionContext directly using chunkContext.getStepContext().getStepExecution().getJobExecution().getExecutionContext().put("inputFile", inputFilename);

2. You can add ExecutionContextPromotionListener to your tasklet step and then do chunkContext.getStepContext().getStepExecution().getExecutionContext().put("inputFile", inputFilename);
