Java 为什么Hibernate manytone不能正确持久化？

我有两个实体用户和愿望：

@Entity
@Table(name = "T_USER")
public class User implements Serializable {

    @Column(length = 50)
    private String lastname;

    @Column(length = 50)
    private String firstname;

    @OneToMany(mappedBy = "user",cascade = CascadeType.ALL,fetch = FetchType.EAGER)
    @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
    private Set<Wish> wishes = new HashSet<Wish>();

    // getters and setters

}

@Entity
@Table(name = "T_WISH")
public class Wish implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "title")
    private String title;


    @Column(name = "description")
    private String description;

    @ManyToOne
    private User user;

    // getters and setters

    }

为什么没有设置招聘人员id。

您的用户类没有@id附加字段。

什么招聘人员id？我在你发布的代码中没有看到这些。

Wish wish = wishRepository.save(wish);
        user.getWishes.add(wish);
    User userSaved =    userRepository.save(user);
