我一直在构建一个应用程序，我终于得到了前端，并返回到communicate.in我的springboot控制器我得到了一个新的错误。从我的研究发生的一个问题，从有多到一的关系，一个解决方案是json忽略。但问题是，json信息显然是ignored.how我可以从我的控制器保存多个用户的一个示例。没有得到这个错误

我的用户类

@JsonIdentityInfo(
        generator = ObjectIdGenerators.PropertyGenerator.class,
        property = "id")
    @Getter
    @Setter
    @Builder
    @AllArgsConstructor
    @NoArgsConstructor
    @Entity
    @Table(name = "user", uniqueConstraints = @UniqueConstraint(columnNames = "email"))
public class User {


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

    @Column(name = "first_name", nullable = false)
    private String firstName;
    @Column(name = "middle_name")
    private String middleName;
    @Column(name = "last_name", nullable = false)
    private String lastName;
    @Column(nullable = false)
    private Date dob;
    @Column(name = "phone_number", nullable = false)
    private String phoneNumber;

    @Column(nullable = false)
    private String email;

    @Column(nullable = false)
    private String password;
    @Column(nullable = false)
    private Boolean isActive;

    @Column(name = "email_config")
    private String emailConfig;

    @OneToOne(mappedBy = "user")
    private Employee employee;

    @ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinTable(

            joinColumns = @JoinColumn(
                    name = "user_id", referencedColumnName = "id"),
            inverseJoinColumns = @JoinColumn(
                    name = "role_id", referencedColumnName = "id"))

    private Collection < Role > roles;

    @OneToMany(fetch=FetchType.LAZY, mappedBy="user")

    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "gender_id", nullable = false)
    private Gender gender;

    @ManyToOne(fetch = FetchType.LAZY, optional = false)
    @JoinColumn(name = "account_privilege_id")
    private AccountPrivilege accountPrivilege;

    @ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    @JoinTable(
            name = "user_offer",
            joinColumns = @JoinColumn(
                    name = "user_id", referencedColumnName = "id"),

    private Collection < PropertyOffer> propertyOffers;

    @OneToMany(fetch=FetchType.LAZY, mappedBy="user")
    private Set<Building> buildings;

    @OneToMany(fetch=FetchType.LAZY, mappedBy="user")

    public User(String firstName, String lastName, Date dob, String phoneNumber, String email,
                String password, Collection < Role > roles, Gender gender, AccountPrivilege accountPrivilege)
    {
        super();
        this.firstName = firstName;
        this.lastName = lastName;
        this.dob = dob;
        this.phoneNumber=phoneNumber;
        this.email = email;
        this.password = password;
        this.roles = roles;
        this.gender=gender;
        this.accountPrivilege= accountPrivilege;
    }

}

与之具有多对多关系的两个类。

@JsonIdentityInfo(
        generator = ObjectIdGenerators.PropertyGenerator.class,
        property = "id")
    @Getter
    @Setter
    @Builder
    @AllArgsConstructor
    @NoArgsConstructor
    @Entity
    @Table(name = "gender")

public class Gender {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @Column(nullable = false)
    private String gender;
    @OneToMany(fetch=FetchType.LAZY, mappedBy="gender")
    private Set<User> users;

}

@JsonIdentityInfo(
        generator = ObjectIdGenerators.PropertyGenerator.class,
        property = "id")
@Getter
@Setter
@Builder
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(name = "account_privilege")
public class AccountPrivilege {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    @Column(name = "enable_slideshow", nullable = false)
    private Boolean enableSlideshow;
    @Column(name = "privilege_name", nullable = false)
    private String privilegeName;
    @Column(nullable = false)
    private float priority;
    @Column(name = "privilege_price", nullable = false)
    private float privilegePrice;
    @OneToMany(fetch=FetchType.LAZY, mappedBy="accountPrivilege")
    private Set<User> users;
}

使用Jackson的托管引用。
https://www.baeldung.com/jackson-bidirectional-relationships-and-infinite-recursion
此外，最佳实践是将JPA实体Map到控制器的一组单独的pojo。由于这个原因，像MapStruct这样的Map框架可以消除所有的样板文件。走这条路可以同时避免这个问题，并使pojo不那么混乱。
