here is my actual implementatipn of UserAuthHeaderParamValueFactoryProvider class

import javax.inject.Inject;
import javax.inject.Singleton;

import org.glassfish.hk2.api.Factory;
import org.glassfish.hk2.api.ServiceLocator;
import org.glassfish.jersey.server.internal.inject.AbstractContainerRequestValueFactory;
import org.glassfish.jersey.server.internal.inject.AbstractValueFactoryProvider;
import org.glassfish.jersey.server.internal.inject.MultivaluedParameterExtractorProvider;

    import org.glassfish.jersey.server.model.Parameter;

    @Singleton
    public class UserAuthHeaderParamValueFactoryProvider extends AbstractValueFactoryProvider {

        @Inject
        protected UserAuthHeaderParamValueFactoryProvider(MultivaluedParameterExtractorProvider mpep, ServiceLocator locator) {
            super(mpep, locator, Parameter.Source.UNKNOWN);
        }

        @Override
        protected Factory createValueFactory(Parameter parameter) {
            Class classType = parameter.getRawType();

            if (classType == null || (!classType.equals(String.class))) {
                return null;
            }

            return new AbstractContainerRequestValueFactory() {
                @Override
                public String provide() {
                    //you can use get any header value.
                    return getContainerRequest().getHeaderString("Authorization");
                }

            };
        }
