Spring Batch read different csv files and xml output

Question

I have a requirement where I need to read 4 different csv files. These have to be read line by line. All files have different number of columns and values.

After processing, I have to generate the output in XML.

If someone can please throw some light, that how to achieve this?

Thanks

Spring Batch has a reader interface. You can write your own reader class which can have 4 individual FlatFileItemReaders and read them until all are done.

The writer is also an interface that you can implement yourself. You'd override the write method and do whatever you needed to do.
