How to get line number while using FlatFileItemReader

[Chandra_Sivaraman]

Hi

I am using FlatFileItemReader to read a delimited flat file. While reading a particular line as input, I would like to get the corresponding line number in my Mapper class. How shall I do this?

Request your suggestions.

Regards
Chandra

Hi All!!! I don't think Spring Batch supports such a One-To-Many approach out of the box, so my guess is you will have to create a custom ItemWriter<List<YourOutObject>> that delegates the individual objects to FlatFileItemWriter<YourOutObject> You can find examples of delegating writers in the link below...

take a look at the documentation for linemapper, so if you create an own mapper class which implements the linemapper interface you have the linenumber access
