title: Neo4j with spring data - expose field marked with @GraphId
body: <p>I try to use neo4j with spring data @RepositoryRestResource, but in returned json there is no "id" field. How to change this behaviour?</p>
  
  <p>Example output:</p>
  
  <pre><code>{
    "_embedded" : {
      "movies" : [ {
        "name" : "movie1",
       },
     ...
  }
  </code></pre>
  
  <p>My entity:</p>
  
  <pre><code>@NodeEntity
  public class Movie {
  
      @GraphId
      Long id;
  
      String name;
  
      // getters and setters omitted for brevity
  }
  </code></pre>
  
  <p>My repo:</p>
  
  <pre><code>@RepositoryRestResource(collectionResourceRel = "movies", path = "movies")
  public interface MovieRepo extends GraphRepository&lt;Movie&gt; { }
  </code></pre>
