    NumericAttribute numeric = new NumericAttribute("numeric");

    List<Attribute> attributes = Arrays.<Attribute>asList(categorical, numeric);

    Map<String, String> properties = new HashMap<>();
    properties.put("p1", "value1");
    properties.put("p2", "value2");

    ModelConfig config = new ModelConfig(attributes, properties);

    ObjectMapper mapper = new ObjectMapper();
    Assert.assertTrue(mapper.canSerialize(config.getClass()));
    String json = mapper.writeValueAsString(config);

    System.out.println(json);//from  w ww . j a  v  a 2s.c om
    System.out.println(config);

    ModelConfig deserialized = mapper.readValue(json, config.getClass());
    assertEquals(config, deserialized);
