Answer 1

I couldn't find a way to make Luca's solution to work, so I extended MultiResourceItemWriter this way:

public class MyMultipleItemWriter extends MultiResourceItemWriter
{
    @Override
    public void write(List items) throws Exception
    {
        this.setResourceSuffixCreator(new MySuffixCreator(items.get(0).getField()));
        super.write(items);
    }
}
