Answer 1

I went with the annotation below in the end

@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")

Thanks for your help guys

Answer 2

if you are using Jackson HttpMessageConverter, you should check their documentation - http://wiki.fasterxml.com/JacksonFeatureBiDirReferences

You should add annotations shown here:

public class NodeList
{
    @JsonManagedReference
    public List<NodeForList> nodes;
}

public class NodeForList
{
    public String name;

    @JsonBackReference public NodeList parent;

    public NodeForList() { this(null); }
    public NodeForList(String n) { name = n; }
}
