Description

This will configure a nomals-scoped bean class used to lookup a CDI bean used as converter for the configuration:

    @Inject
    @ConfigProperty(name = "urlListFromProperties", converter = UrlList.class)
    private List<URL> urlListFromProperties;

assuming we have:

    public class UrlList implements ConfigResolver.Converter<List<URL>>
    {
        @Override
        public List<URL> convert(final String value)
        {
            final List<URL> urls = new ArrayList<URL>();
            if (value != null)
            {
                for (final String segment : value.split(","))
                {
                    try
                    {
                        urls.add(new URL(segment));
                    }
                    catch (final MalformedURLException e)
                    {
                        throw new IllegalArgumentException(e);
                    }
                }
            }
            return urls;
        }
    }
