title: How to convert not all attributes from a java object to json using jackson object mapper
body: <p>I'm searching for a way to convert just a partial object (not all attrbiutes of it) via jackson to json. At the moment I'm using this solution:</p>
  
  <pre><code>User userServed = User.find.byId(id);
  ObjectMapper mapper = new ObjectMapper();
  JsonNode node = null;
  node = mapper.convertValue(userServed, JsonNode.class);
  </code></pre>
  
  <p>It works fine so far.</p>
  
  <p>My Problem is that I have a lot of attributes in the Object I don't want to expose to the json node like lists. Is there a way maybe to select just the needed attributes?</p>
