Question

I need to pass data related to processing an item in between item processors, I don’t need to persist the data, what is the best approach (Note I’m currently using StepSynchronizationManager to access the stepExecution and store the data in ExecutionContext).

Answer 1

What makes you think, that your way – storing the data in StepExecutionContext – is a bad or not the best way ?

You could try it without saving the data in the StepExecution and instead change the items between the processors

public class FirstProcessor implements ItemProcessor<String, String> {...}


public class SecondProcessor implements ItemProcessor<String, OtherClass> {

  public OtherClass process(String item) throws Exception {

     return otherClassObjectWithDataForNextProcessor;

  }
}

public class ThirdProcessor implements ItemProcessor<OtherClass, TargetClass> {...}

public class CustomItemWriter implements ItemWriter<TargetClass> {...}
