The problem of creating tables in JPA - Codes Helper

entity 1 inherits another entity 2. Entity 2 is a public entity with id,createDate and other common attributes, so entity 1 does not need to write these fields, but the table cannot be built, and an error is reported:

Error starting ApplicationContext. To display the conditions report re-run your application with "debug" enabled.

entity 2:

public class BaseDto implements Serializable {
    private static final long serialVersionUID = -8224576499560872755L;

    /**
     * id
     */
    @Id
    @Column(name = "ID", nullable = false, length = 20, unique = true)
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    /**
     * 
     */
    @Column(name = "CREATE_DATE", nullable = false)
    private Date createDate;

    /**
     * 
     */
    @Column(name = "MODIFIED_DATE", nullable = false)
    private Date modifiedDate;

entity 1:

@Entity
@Table(name = "USER")
public class User extends BaseDto {
    private static final long serialVersionUID = 7196020041376158025L;

    /**
     * 
     */
    @Column(name = "USER_NAME", nullable = false, length = 20)
    private String userName;

    /**
     * 
     */
    @Column(name = "USER_AGE", length = 3)
    private Integer userAge;

    /**
     * : 1 , 2 
     */
    @Column(name = "USER_SEX", length = 1)
    private Integer userSex;

is there no way to create a table? Can only id,createDate repeat attributes be written in each entity?
