Jackson with Spring MVC duplicate nested objects not deserializing

Question

I am trying to Convert following POJO to a JSON in @RestController:

@Entity
@Table(name=\"user_location\")
@NamedQuery(name=\"UserLocation.findA         


        

Answer 1

First remove that annotations from your State.java and City.java

@JsonIdentityInfo(generator = ObjectIdGenerators.IntSequenceGenerator.class, property="@id", scope = State.class)

@JsonIdentityInfo(generator = ObjectIdGenerators.IntSequenceGenerator.class, property="@id", scope = City.class)

No need of these annotations and in RestController add return type as @ResponseBody UserLocation . It will give you json of that class.
