import lombok.NoArgsConstructor;

import javax.persistence.*;
import java.time.LocalDateTime;

@AllArgsConstructor
@NoArgsConstructor
@Builder
@Data
@Entity
public class User {

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

    @Column
    private String email;

    @Column
    private String name;

    @Column
    private String password;

    @Column
    private String phone;

    @Column
    private LocalDateTime regDate;
