Spring GS - Creating a Batch Service missing output from db query

Question:

Tag: spring-batch

I have run the complete source for Getting Started - Creating a Batch Service

Knowing that the sample uses the memory-based database provided by the @EnableBatchProcessing, is the db query result expected or it will only be available if data will be persisted permanently?

After adding some debug lines, it seems that the DB query is executed first before the job gets executed. Was this the expected behavior?

Is there anything I'm missing here.

Thanks Alex


Answer:

You aren't missing anything. This is related to issue number 8 for that guide (https://github.com/spring-guides/gs-batch-processing/issues/8). I just created a pull request to address this issue. You can view the PR here (https://github.com/spring-guides/gs-batch-processing/pull/9) until it's merged.

UPDATE
The PR has been merged and the guid has been updated. The new version should no longer have this issue.
