Read comma separated properties with configuration2 in java -

-

i have property: 

move.patternfile.include = *1a.txt,*2a.txt

and i'm trying put in list, using apache commons configuration2.

the code have :

configurations configs = new configurations(); abstractconfiguration config = configs.properties(new file(filename)); config.setlistdelimiterhandler(new defaultlistdelimiterhandler(','));

i can read others properties, 1 want still 1 size list.

this command retrieve values :

list<string> linclude = configuration.getlist(string.class, "patternfile.include");

can please?

based on this appears delimiter has set before properties read file. code below works when run it, generates warning.

parameters params = new parameters(); filebasedconfigurationbuilder<propertiesconfiguration> builder =      new filebasedconfigurationbuilder<propertiesconfiguration>(              propertiesconfiguration.class).configure(params.filebased()              .setlistdelimiterhandler(new defaultlistdelimiterhandler(','))              .setfile(new file("test.properties"))); propertiesconfiguration config = builder.getconfiguration();  list<string> linclude = config.getlist(string.class, "patternfile.include");  system.out.println(linclude.size()); for(string item: linclude){     system.out.println(item); }

test.properties

patternfile.include = *1a.txt,*2a.txt

output

2

*1a.txt

*2a.txt

here warning see when run it:
