@JsonIdentityInfo causing Unsupported Media Type

[Nathan Milota]

Here is my class.  

package com.km.theatretix.entity;

import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;

import com.fasterxml.jackson.annotation.JsonBackReference;
import com.fasterxml.jackson.annotation.JsonIdentityInfo;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.ObjectIdGenerators;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Entity
public class Seat {
	
	@Id
	@GeneratedValue
	private long id;
	
	@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property="id", scope=Long.class)
	@ManyToOne(fetch=FetchType.EAGER)
	@JoinColumn(name="venue_id", referencedColumnName="id", nullable=false)
	private Venue venue;
	
	
	private String section;
	private String row;
	private long seatNumber;
	public long getId() {
		return id;
	}
	public void setId(long id) {
		this.id = id;
	}
	public Venue getVenue() {
		return venue;
	}
	public void setVenue(Venue venue) {
		this.venue = venue;
	}
	public String getSection() {
		return section;
	}
	public void setSection(String section) {
		this.section = section;
	}
	public String getRow() {
		return row;
	}
	public void setRow(String row) {
		this.row = row;
	}
	public long getSeatNumber() {
		return seatNumber;
	}
	public void setSeatNumber(long seatNumber) {
		this.seatNumber = seatNumber;
	}
	
	
	

The problem is, without the annotation, I can't get it to work properly on a GET request.   Is there any workaround?

I guess the objects cannot be serialized into JSON and that causes unsupported media type.
