This discussion is about representing comma separated lists for String[],
int[] and long[]. An example representing String[] as comma separated list
would be,
{
"StringArr": "item1,item2,item3"
}
To represent this comma separated format, we will use @JsonFormat
annotation with a pattern of something like "\w+(,\w)*". The pattern
represented here is a regex pattern which can be applied on a string to get
the list of values while deserialization, but while serialization we cannot
use this regex pattern to serialize an array into a string separated by a
delimiter.
One suggestion would be to use a static pattern for representing the comma
separated values like "\w,\w" which we can use to serialize and deserialize
the comma separated scalars and strings.
Let me know your thoughts.
Thanks,
Lokesh
