title: Produce several items in Spring Batch chunk-tasklet
body: <p>I'm new to SpringBatch. I'm configuring a <code>&lt;chunk&gt;</code> tasklet with reader/writer/processors. I want to produce -for each read item- zero or more command-items that the writer executes.</p>
  
  <p>AFAIK the ProcessorItem interface only let me produce one item for each read item or null. Of course I can produce List but I would like a cleaner approach.</p>
  
  <p>Maybe I'm not using the right tool and there's another thing for not one-to-one-related readers/producers vs. writer/consumers... but I don't know.</p>
  
  <p>Can someone lead me in the right direction?</p>
  
  <p>Thanks!</p>
