title: Reading multiple files in a folder and parsing it and writing to another folder
body: <p>I am new to spring batch. My requirement is, I have a folder say D:\xyzfolder\source which is having 25 flat files. Using spring batch I need to read and implement some business logic and write all 25 files with the same name into a different folder say D:\xyzfolder\destination</p>
  
  <p>Currently, I am using <code>MultiResourceItemReader</code> and reading all the 25 files from the source folder and I am able to write into a single file using <code>FlatFileItemWriter with  setResource(outputResource)</code> but my requirement is to write as 25 different files. Please suggest how to achieve the above requirement</p>
