我正在尝试运行以下简单示例，但出现错误。

我正在使用@CreatedDate。但是，当我使用Rest端点保存Student对象时，它不会创建日期并抛出给定的异常。

在我的休息终点，我有

 @PostMapping("/students")
 public Student createStudent(@Valid @RequestBody Student student){
    return studentRepository.save(student);
 }

这是我的实体...

@Entity
@Table(name = "students")
@EntityListeners(AuditingEntityListener.class)
@JsonIgnoreProperties(value = {"createdAt", "updatedAt"}, allowGetters = true)
public class Student implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @NotBlank
    private String name;
    @NotBlank
    private String surname;

    @Column(nullable = false, updatable = false)
    @Temporal(TemporalType.TIMESTAMP)
    @CreatedDate
    private Date createdAt;

    @Column(nullable = false)
    @Temporal(TemporalType.TIMESTAMP)
    @LastModifiedDate
    private Date updatedAt;

错误：
