itemProcessor in Composite Item Writer model

[marwan simaan]

Hello,

I spring batch 1.1.x version, we could define a CompositeItemWriter with several item writers executed in sequence. These item writers can be an implementation of an ItemTransformerItemWriter allowing to have several processing/writing for the same chunk.

Did we lose this capability in 2.0.0? I cannot seem to find a way to couple an ItemProcessor with an ItemWriter.

The work-around that I found is injecting an ItemProcessor in my custom ItemWriter (following the old ItemTransformerItemWriter) model.

Do you agree? or is there a better way?

Thanks,
Marwan

I'm not sure there's much reason for injecting an ItemProcessor into a custom ItemWriter. It probably makes more sense to just do the "processing" in the ItemWriter before writing the item out.

Something like ItemTransformerItemWriter can be helpful for chunk transforming. The ItemProcessor in Spring Batch 2.0 doesn't support chunk processing. Only one item per call.
