有一個(gè)奇怪的問(wèn)題，無(wú)法弄清楚如何處理。有簡(jiǎn)單的POJO：@Entity@Table(name = "persons")public class Person {    @Id    @GeneratedValue    private Long id;    @Column(name = "first_name")    private String firstName;    @Column(name = "middle_name")    private String middleName;    @Column(name = "last_name")    private String lastName;    @Column(name = "comment")    private String comment;    @Column(name = "created")    private Date created;    @Column(name = "updated")    private Date updated;    @PrePersist    protected void onCreate() {        created = new Date();    }    @PreUpdate    protected void onUpdate() {        updated = new Date();    }    @Valid    @OrderBy("id")    @OneToMany(mappedBy = "person", fetch = FetchType.EAGER, cascade = CascadeType.ALL, orphanRemoval = true)    private List<PhoneNumber> phoneNumbers = new ArrayList<>();    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    public String getFirstName() {        return firstName;    }    public void setFirstName(String firstName) {        this.firstName = firstName;    }    public String getMiddleName() {        return middleName;    }    public void setMiddleName(String middleName) {        this.middleName = middleName;    }    public String getLastName() {        return lastName;    }    public void setLastName(String lastName) {        this.lastName = lastName;    }    public String getComment() {        return comment;    }其余端點(diǎn)：@ResponseBody@RequestMapping(method = RequestMethod.GET)public List<Person> listPersons() {    return personService.findAll();}在json響應(yīng)中，除了Id之外，還有其他所有字段，我需要在前端編輯/刪除人員。如何配置Spring Boot來(lái)序列化ID？這就是現(xiàn)在的響應(yīng)：[{  "firstName": "Just",  "middleName": "Test",  "lastName": "Name",  "comment": "Just a comment",  "created": 1405774380410,  "updated": null,  "phoneNumbers": [{    "phoneNumber": "74575754757"  }, {    "phoneNumber": "575757547"  }, {    "phoneNumber": "57547547547"  }]}]UPD具有雙向休眠映射，可能與問(wèn)題有關(guān)。
