Spring批处理组验证来自FlatFileItemReader的输入行

Question

I have a spring batch job where in I use FlatFileItemReader and populate it to Pojo objects (items). My file has a footer line that gives me the number of records in the file. I need to validate that my List has that many objects.

I cannot do it through ItemProcessor as it gives me only one item at a time. Is there any other way to do such a validation in spring batch?

Thanks Paddy

Spring's FlatFileItemReader provides a feature to skip the number of line at the top and end. This issue got solved using them. Don't have a postable code, but was led to the answer from the the reader writer documentation.
