ValueConverter
that converts CSV values to List of Strings. A null
or empty value (once
trimmed) will be returned as an empty list (behaviour which can be overridden via the convertMissingValue(java.lang.String, java.lang.String, java.lang.Object...)
method). The message keys and default values used are:
The patterns are also optionally injectable via Properties
in the constructor and take precedence over
the ones configured in the messages resources.
