Spring Batch DelimitedLineTokenizer class quoteCharacter property behavior

Question

I have a item reader as below:

Answer 1

A string is intended to be quoted if it starts/ends with quote char. In your example:

oneColumn|twoColumn|~three|Column~|fourColumn

and you'll get three|Column You have to quote string if it contains a separator, space, newline or the quoting char itself; quoting char must be doubled if part of value(see here)
