FlatFileItemReader ignoring line starts with #

[tirtawn]

Bug description
FlatFileIteamReader skip any lines if the line starts with #
Example:
email
hello
#hello2 --> this will be skipped
hello3
hello4

Environment
Spring Batch 2.7.10
Java 17
H2 Mem / Postgres/SQL Server

Steps to reproduce
I have attached 2 files
import.txt
springdemo2.zip

compile and run the jar. The program will import the import.txt and print the data to the console. (it will skip line #2) .

Expected behavior
All the lines inside the file will be read.

Minimal Complete Reproducible example
springdemo2.zip and import.txt is attached
just compile into jar file and put the import.txt inside the target directory.
Running the jar file should skip the line with the #
as shown below:

Email: ExceptionUserEntity(email=hello3)
Email: ExceptionUserEntity(email=hello4)

--> Notice: hello2 is skipped

Hi @tirtawn, this is actually a feature as comments usually start with #.

If this doesn't work for you, you can use FlatFileItemReader#setComments to set different comment prefixes. To disable this feature completely, you can pass an empty array to that method.

Got it. Thanks for the confirmation.
