How to set delimiter value in spring package FlatFileReader?

Question

I am new to spring package. My task is to develop code that reads a flat file, where the values ​​are separated by a pipe "|". I found that I can do this with FlatFileReader. But I don’t understand how to set the delimiter value while reading and how to map each column to my POJO member variables.

The following are sample values ​​in a flat file.

3345|742|0|N

3346|743|1|A

3347|742|0|N

3348|742|1|C

3345|743|0|K

Thanks in advance.
