For those asking, an alternative approach would be to use fasterxml's JsonIdentityInfo and to annotate your class with:

import com.fasterxml.jackson.annotation.JsonIdentityInfo;
import com.fasterxml.jackson.annotation.ObjectIdGenerators;
@JsonIdentityInfo(generator=ObjectIdGenerators.PropertyGenerator.class, property="id")
public class Account implements java.io.Serializable {
....
private Long id;
}
