java - Parse multi-section file with Spring Batch -


i'd use spring batch parse following multi-section file.

  1. the headers listed vertically
  2. the number of headers changes 1 file next
  3. there multiple, distinct "begin/end" tokens
  4. each section (meta, head, data, footer) requires different mappers/tokenizers

any ideas?

start-of-file programname=getdata dateformat=yyyymmdd  start-of-fields id name end-of-fields  timestarted=tue may  6 16:17:15 edt 2014 start-of-data 0|craig| 1|john| 2|tim| 3|| end-of-data datarecords=4 timefinished=tue may  6 16:49:38 edt 2014 end-of-file

the way write custom itemreader<> parse every section , return custom bean: 1 bean header , 1 bean start-of-fields section preparation (store data step execution context).
start-of-data/end-of-data section: data can parsed custom flatfileitemreader (custom because need stop on end-of-data , not on classic eof) using header bean gathered before row mapping.
hope can start.
