Spring Batch 2.0 – Part III – From Database to Flat File
In Part-II of this series on Spring Batch, I went through an example of reading from a flat file and persisting into the database. In this article I will go through the reverse. Read 200,000 rows from the database and export it into a comma separated flat file. Continue reading
