我的服务将http方法放入Spring Boot控制器

//url=http://localhost:8090/SpringMVC/user/modify-user
@PutMapping("modify-user")
   @ResponseBody
   public User modifyUser(@RequestBody User u){
       return userService.updateUser(u);
   }

我的服务将http方法放入Spring Boot服务

public User updateUser(User u) {
        userRepository.save(u);
        return u;
    }

我的用户类Spring Boot实体

@Entity
@Table
@Setter
@Getter
@NoArgsConstructor
@ToString
public class User implements Serializable {
    public User(String nom, String prenom, Date dateNaissance, String email, String password, CategorieUser categorieUser, Profession profession) {
        this.nom = nom;
        this.prenom = prenom;
        this.dateNaissance = dateNaissance;
        this.email = email;
        this.password = password;
        CategorieUser = categorieUser;
        Profession = profession;
    }

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name="idUser")
    private Long idUser;
    private String nom;
    private String prenom;
    @Temporal(TemporalType.DATE)
    private Date dateNaissance;
    private String email;
    private String password;
    private CategorieUser CategorieUser;
    private Profession Profession;

    private String picture;
    private Integer phoneNumber;
    private String adresse;//test

    @ManyToMany(cascade = CascadeType.PERSIST,fetch = FetchType.EAGER)
    private Set<Role> role;

    @OneToMany(mappedBy = "user",cascade = CascadeType.ALL)
    private Set<Facture> facture;

    @OneToMany(mappedBy = "user_avis",cascade = CascadeType.ALL)
    private Set<AvisUser> avisUser;



}

问题是由与我相关的类中的注释@JsonManagedReference引起的，我删除了它，一切正常
