WebResource resource = client.resource(urlStr); 
resource.accept(MediaType.APPLICATION_JSON_TYPE, MediaType.APPLICATION_XML_TYPE);
GenericType<List<EMailInformations>> genericType = new GenericType<List<EMailInformations>>() {};
List<EMailInformations> response = null; 
try{ 
    response = resource.get(genericType); 
} catch (UniformInterfaceException ue) { 
    ClientResponse clientResponse = ue.getResponse(); 
}

类EMailInformations

@XmlRootElement
public class EMailInformations {
    private long id;

    public EMailInformations(){

    }

    public EMailInformations(long id) {
        super();
        this.id = id;
    }
        //getters & setters ...
}
