复合主键和外键映射问题

Question

我有两个实体Employee和Phone。在具有相同复合主键的情况下，并且对于电话实体，主键充当外键。当尝试创建OneTONe关系时，我在下面面临的问题得到了解释。建议我尽快解决此问题

        //Employee 
        @Entity(name = "Employee")
        @Table(name = "employee")
        @IdClass(EId.class)
        public class Employee {

            @Id
            @GeneratedValue(strategy = GenerationType.AUTO)
            @Column(name = "c_id")
            private int id;

            @Id
            @GeneratedValue(strategy = GenerationType.AUTO)
            @Column(name = "uuid")
            private int uuid;

            private String name;

            @OneToOne(cascade = CascadeType.ALL, mappedBy = "employee")
            private Phone phone;

//Getters and Setters }
        //Phone
        @Entity(name = "Phone")
        @Table(name = "phone")
        @IdClass(PId.class)
        public class Phone {

            @Id
            @Column(name = "num")
            private int id;

            @Id
            @Column(name = "uuid")
            private int uuid;

            private String name;

            @OneToOne
            @MapsId
            @JoinColumns({ @JoinColumn(name = "num", referencedColumnName = "c_id"),
                    @JoinColumn(name = "uuid", referencedColumnName = "uuid") })
            private Employee employee;
        //Getters and Setters }
        //Repo

        @Repository
        @Transactional
        public class Repo {
            @Autowired
            EntityManager em;

            public void insert() {

                Employee employee = new Employee();
                employee.setName("Azum");

                Phone phone = new Phone();
                phone.setName("Nokia 6.1 plus");

                employee.setPhone(phone);
                phone.setEmployee(employee);

                em.persist(employee);
            }
        }

我正在共享主键。.当插入数据时，由于此应用程序未共享给Phone的员工主键数据引发Integarty问题
