I am trying to create onetoone mapping between two tables where the parent key primary key acts as the primary key for child as well. While trying to save parent I am getting the following error.

Please find the below console log, model classes and service class used for the same. Can someone pls help to resolve the error.

Basically want to transfer the order id from order class to order id under compensation using crud repo.

Parent class:

    package com.newModel;

import java.io.Serializable;



import javax.persistence.CascadeType;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.FetchType;

import javax.persistence.Id;

import javax.persistence.OneToOne;

import javax.persistence.Table;



@Entity

@Table(name="ORDERS")

public class Order implements Serializable {

    private static final long serialVersionUID = 1L;



    @Id

    @Column(name="ORDER_ID")

    private String orderId;



    @Column(name="ACCESS_ID")

    private String accessId;



    @OneToOne(cascade=CascadeType.ALL,mappedBy="order",fetch=FetchType.EAGER)

    private Compensation compensation;



//getters & setters 

    }

Child Class:

package com.newModel;



import java.io.Serializable;



import javax.persistence.CascadeType;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.Id;

import javax.persistence.JoinColumn;

import javax.persistence.MapsId;

import javax.persistence.NamedQuery;

import javax.persistence.OneToOne;

import javax.persistence.Table;







@Entity

@Table(name="COMPENSATION")

@NamedQuery(name="Compensation.findAll", query="SELECT o FROM Compensation o")

public class Compensation implements Serializable {

    private static final long serialVersionUID = 1L;



    /*@Id

    @Column(name="ORDER_ID")

    private String orderId;*/



    @Column(name="CHANNEL_DEALER_CODE")

    private String channelDealerCode;



    //bi-directional one-to-one association to Order



    @Id

    @OneToOne(cascade=CascadeType.ALL)

    @JoinColumn(name="ORDER_ID")

    private Order order;





}

Service class:

package com.sample.service;



import javax.ws.rs.core.Response;



import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;



import com.newModel.Order;





@Component

public class MobilityServiceImpl implements MobilityService {





    @Autowired

    private MobilityRepository mobilityRepo;



    @Override

    public Response getOrderDetails(String orderId) {



        Order orderDetails=mobilityRepo.findByOrderId(orderId);



        return Response.ok(orderDetails).build();

    }



    @Override

    public Response saveOrderDetails(Order orderDetails) {



        orderDetails.getCompensation().setOrder(orderDetails);



        Order orderResponse =mobilityRepo.save(orderDetails);

        String resp=orderResponse.getOrderId()+" is Success";

        return Response.ok(resp).build();

    }



    }

  "compensation": {

                }

}

In yout Compensation entity you still need to have id and Order in separate properties and use MapsId to have the same id

@Entity

@Table(name="COMPENSATION")

@NamedQuery(name="Compensation.findAll", query="SELECT o FROM Compensation o")

public class Compensation implements Serializable {

    private static final long serialVersionUID = 1L;



    @Id

    private String id;



    @Column(name="CHANNEL_DEALER_CODE")

    private String channelDealerCode;



    @OneToOne(fetch = FetchType.LAZY)

    @MapsId

    private Order order;

}
